114 guides published. Each one answers a single operational question and shows the arithmetic behind the answer.
7 minAmazon is removing the seller-eligibility gate on the Featured Offer. The price gate stays.
Amazon's July 6, 2026 announcement removes the first step in Featured Offer selection — the seller-performance screen — in every store by the end of 2026. The ranking step, and the pricing rules that suppress offers, are unchanged. What the announcement says, what it does not say, and what to check in your account.
One of two steps removed; selection criteria unchanged
10 minPricing Health: the two tabs, the three offer states, and the order to fix them when the Featured Offer disappears
Every price-driven Featured Offer loss lands in one of three Pricing Health rows: deactivated for a suspected pricing error, ineligible against the Competitive External Price, or eligible within 5% and not winning. What each row means in Amazon's words, the fix that clears it, and the margin check to run first.
Eligible-and-close band: within 5% of the Featured Offer price — Amazon
5 minAmazon's first $200 billion quarter — and the 26% number that matters more to sellers
Q2 2026: net sales up 20% to $200.6 billion, advertising up 26% to $19.8 billion. Demand is accelerating — and so is the pay-to-play pressure on organic visibility. The seller read, plus what to watch at Accelerate on 22-September 24.
5 mineBay closes the $1.4B Depop deal — and Etsy cuts 200 jobs six days after banking it
The Depop acquisition completed with eBay pledging to run the resale platform intact; Etsy announced 200 layoffs days after receiving the cash. What the reshuffle signals for sellers on both platforms — and why fee structures are the thing to watch next.
6 minLabor Day week: the short-week trap in your inbound plan
September 7 removes a working day from carriers, ports and receiving docks in the same week your Q4 freight is supposed to move. What a holiday week actually does to transit and check-in times, and the two adjustments that cost nothing this week and save a scramble next week.
5 minNew rule: AI-generated people in your images must now carry a metadata tag
Amazon now requires product images and A+ Content featuring photorealistic AI-generated people to include 'contains-synthetic-performer' in the image file's XMP metadata before upload — with real people, AI-edited real people and non-photorealistic figures reported exempt.
8 minThe free Rufus research most brands never open
Two data sources already inside Seller Central tell you what Amazon's AI wants to know about your product: the Search Query Performance dashboard and the questions Rufus itself displays on your listing. How to read both, and turn them into listing edits — without buying a single tool.
5 minTikTok Shop is testing a Prime of its own: Shop Plus at $6, $10 and $15 a month
TikTok Shop is testing a paid membership bundling free shipping, discounts and coupons at three monthly tiers — a deliberate shift from impulse buying toward repeat purchasing. What a loyalty layer would mean for sellers still digesting the 8% fee.
8 minFrom day 181 to month 15: the sell-down, liquidate or remove decision at every step of the aged-inventory ladder
The storage guide explains the aged-inventory surcharge. This one decides. At each band from day 181 to the new 15-month tier, here is the monthly cost of holding one unit, the cost of removing it, and the discount at which selling it down beats both.
Decision points: day 150, day 240, day 330, month 12
7 minFBT's fixed-dollar problem: why cheap products lose on TikTok Shop
Fulfilled by TikTok prices per unit in dollars while every other cost scales in percentages — at roughly $2.86-$4.28 per unit, that flat fee is ~9% of a $40 sale and about a quarter of a $15 one. The SKU-selection rule that falls out of the arithmetic, sharpened by August's move to 8%.
~$2.86–$4.28 per unit (seller-tool estimate)
6 min984 million titles later: the 75-character era is fully here
Amazon's August 13 FAQ reports more than 984 million product titles updated since the June announcement. The 75-character cap has been in force since July 27; over-limit titles are being rewritten by AI on Amazon's schedule — and only brand-registered sellers get a review window.
9 minEtsy's Offsite Ads: the fee you can refuse exactly once
Under $10,000 in trailing sales the program is optional at 15%; cross the threshold once and it is mandatory for the life of the shop at 12% — Etsy's own policy says so. The economics at handmade price points, the $100 cap, and the decision to make before the threshold makes it for you.
12-15% on attributed orders
7 minAmazon now caps referral fees on your first 200 units of a new FBA product — if you inbounded on or after July 30
The 2026 FBA New Selection Program replaced the old rebate with an instant referral-fee cap: 10% on the first 100 units of a new branded parent ASIN, 5% on the next 100, plus 120 days of free storage, returns and liquidations. The enrollment window closes October 31, 2026. Earlier coverage — including ours — quoted a $25,000 threshold that belongs to a different program.
10% cap on units 1–100, 5% on 101–200, per new parent ASIN
6 minQ4 unit cost worksheet: what one unit costs to fulfil from October 15, tier by tier, 2025 versus 2026
The peak fee guide explains the rule. This page is the arithmetic: base 2026 fee, plus the peak uplift, times 1.035, for six representative size tiers — against what the same unit cost last peak. Copy the sheet, replace the fees with yours.
Q4 unit cost = (base + peak uplift) × 1.035
5 minYour Amazon contract changed on Sunday: no more pledging future revenue
Effective August 24, 2026, the Business Solutions Agreement bars sellers from transferring rights under the agreement and from pledging future Amazon sales revenue as collateral — a quiet clause with loud consequences for anyone using revenue-based financing.
5 minThe Q4 deal clock is running: Prime Big Deal Days submissions close September 8
Deal-submission windows for the holiday season: Prime Big Deal Days closes September 8, Black Friday/Cyber Monday closes October 20 — with a $50-per-deal early-submission discount for BF/CM until September 5. The dates, and the math to run before opting in.
Deal deadlines: Sep 8 / Oct 20
8 minThe Q4 freight window: counting backwards from October 15
Peak fulfillment fees start October 15 and Q4 storage steps up October 1 — which means your freight booking date is already decided by arithmetic, not preference. The backwards count from selling window to PO date, mode by mode.
10 minRufus answers 250 million shoppers now. Here is what that does to a fee-focused listing.
Amazon's AI assistant is at 250M+ users and 38% of Black Friday 2025 sessions — yet classic search still drives 80-85% of discovery. What to change in a listing, in priority order, without burning money on the hype: backend attributes, Rufus's own prompted questions, image alt text, and the partial attribution data in Brand Analytics.
9 minWalmart is paying new sellers to show up: what the $75K New-Seller Savings actually contains
Walmart's New-Seller Savings 2026 runs to January 31, 2027: 20-40% off base referral fees by GMV tier, $2,000 in WFS credits, $1,500 in ad credits — and an opt-in step most sellers will miss. What the discounts are really worth at normal volumes, per Walmart's own terms.
20-40% off referral fees, first year
9 minEvery recurring deadline on this site, on one calendar
Ninety guides produce about thirty recurring dates: daily checks, monthly reviews, quarterly rebuilds, and a handful of fixed calendar deadlines that decide a whole quarter. This is the assembled version.
Two minutes daily · one hour monthly
8 minAmazon reads every message you send a customer, and 'we're a family business' can get it blocked
Messaging policy divides into necessary and proactive permitted messages. AI scanning every message and blocking persuasive language, external links, emojis, incentives and even the buyer's first name.
If unsure, use Request a Review instead
9 minA card in the box asking customers to contact you before leaving a negative review is a policy violation
Inserts are allowed. Review gating is not, incentives are not, and redirecting shoppers off Amazon is not. The distinction is narrower than most templates assume — and the safest version removes review language entirely.
Inserts allowed · review gating is not
9 minAmazon's system flags patterns, not proven violations — and it does not tell you which pattern
A review manipulation notice names no reviews, no messages and no service. You identify the trigger yourself, on an account that may already be suspended. false positives as documented and common in 2026.
Patterns flagged · triggers not disclosed
8 minOn July 1, 2027 the de minimis exemption stops being suspended and starts being repealed
The 2025 suspension was an executive action, reversible by another one. The One Big Beautiful Bill Act repeals Section 321 for commercial shipments by statute — which removes the possibility that any of this reverts.
Statutory repeal, not a suspension
9 minTikTok Shop quietly moved its US referral fee to 8%. Your first full settlement under it lands this month.
Trade coverage dates the increase from 6% to 8% on most non-food US categories to August 4, 2026 — months after the promotional 1.8% rate ended in January. Two points reads small; on a thin-margin unit it is a fifth of the profit. The math, the conflicting sources, and the three checks to run in Seller Center this week.
US referral: 6% → 8% on most non-food categories (August 4, 2026, trade reports)
9 minAmazon Renewed asks for $50,000 of invoices before it lets you sell one refurbished unit
The program is invoice-gated, defect-rate-gated and warranty-backed. For Apple items the invoice threshold is $2.5 million. It is not a route for clearing your own returns — it is a business you either already run or do not.
Entry: $50,000 in invoices, ODR ≤ 0.8%
10 minPackaging is the only decision that changes six fees at once, and it is fixed before you order
Cubic feet multiply every storage layer. Dimensions set the size tier. Weight sets the fulfillment fee. Durability decides SIPP eligibility. Prep complexity sets a per-unit rate. And all of it is decided at tooling.
Decided at tooling, charged for years
10 minAn inspection costs $150 to $300 a day. A rejected container costs the container.
Pre-shipment inspection is the last moment you can refuse goods while the supplier still holds them and you still hold the balance payment. After that you are arguing about a refund from another jurisdiction.
PSI: $149–$400 per man-day
10 minA sourcing agent who selects the factory and inspects it is checking their own work
Agents solve real problems — language, verification, coordination, consolidation. The structural question is whether the party choosing your supplier is also the party telling you the goods are acceptable, and how they are paid.
Ask how they are paid before what they charge
9 minThe balance payment is your last piece of use. Most sellers give it up before the inspection.
Deposit, production, inspection, balance, shipment — in that order. Reverse any two steps and you are negotiating a refund instead of a rework, from a jurisdiction where you have no practical recourse.
Inspect, then pay, then ship
9 minSome products carry a duty that has nothing to do with your tariff code, your origin, or anything you can plan for
Antidumping and countervailing duties are imposed on specific products from specific countries, at rates set case by case, and an expanding docket. They also force formal entry regardless of shipment value.
Case-by-case rates · formal entry regardless of value
8 minThe de minimis suspension made most sellers importers of record. Importers of record need a bond.
A customs bond is a guarantee to CBP that your duties will be paid. It is mandatory on almost all formal entries, may be required on informal ones, and its size scales with duty — which rose sharply.
Continuous bond: greater of $50,000 or 10% of prior-year duties (CBP)
9 minIf you export any of what you import, you may be owed up to 99% of the duty back
Duty drawback refunds duty paid on imported goods that are subsequently exported — in the same form or after manufacturing. it as underutilised by importers who export part of their production.
Refund of up to 99% of duty paid
10 minIf a trading company sits between you and the factory, you may be paying duty on their margin
First sale valuation lets qualifying importers declare duty on the manufacturer's price rather than the intermediary's. Reported savings of 15% to 25% of the dutiable base — and a bill introduced in February 2026 would end it.
Reported: 15–25% off the dutiable base
9 minChanging the product to change the duty rate is legal. Changing the paperwork is fraud.
Tariff engineering means designing a product so it classifies under a lower-duty heading. The line between it and evasion is clear and worth understanding precisely — and the tariff schedule changed twice in the first two months of 2026.
HTS 2026 Basic Edition, then Revision 4 by February 25
11 minShipping Chinese goods through Vietnam does not make them Vietnamese
Country of origin is where a product was substantially transformed, not where it was shipped from. Repackaging, relabeling and simple final assembly do not qualify — and CBP will be enforcing the distinction more rigorously.
Substantial transformation, not final packaging
9 minA Foreign Trade Zone is legally outside US customs territory while sitting inside the country
Goods enter without duty until they leave the zone. Re-export and no duty is owed at all. And where you assemble inside the zone, you may pay whichever rate is lower — the components' or the finished product's.
Deferral · elimination on re-export · inverted tariff
8 minUnmarked goods carry a 10% duty on top of everything else
19 USC 1304 requires most imports to be marked with their country of origin, conspicuously, legibly and permanently. Goods that are not will attract a 10% ad valorem marking duty — and CBP may refuse entry entirely.
Marking duty: 10% ad valorem, on top of duty
9 minYou discover you have been importing under the wrong code. There are two doors, and one closes in 180 days.
If you underpaid, a prior disclosure filed before CBP finds it changes the exposure. If you overpaid, a protest recovers it — but only within 180 days of liquidation, per entry, and the window runs quietly.
Protest window: 180 days from liquidation, per entry
10 minYour duty rate is not one number. It is four layers, and only one of them is in the tariff schedule.
Base MFN duty, Section 301, Section 232 and IEEPA measures stack on the same entry. Sources report effective rates commonly at 20% to 30% on ordinary consumer categories and far higher on some — and the structure keeps changing.
Four layers · one HTS code
10 minThe freight line is the smallest item on a freight bill
One published breakdown puts ocean freight at $80 to $200 of a $485 to $1,130 total for a single cubic meter. Comparing forwarders on the freight quote compares the one line that varies least.
Ocean freight: ~20% of the invoice
11 minAmazon fines you for holding too much and for holding too little. The gap between them is your reorder point.
Storage escalates above roughly 45 days of cover. A per-unit fee applies below a 28-day threshold. Your lead time is longer than both. That is the whole problem, and it has an arithmetic answer.
Corridor: 28 days (Amazon) to ~45 days (IPI practice) · lead time 60–90
10 minSix sources give eBay's fee as 12.9%, 13.25%, 13.35%, 13.6%, 14.0% and 15.3%
They are mostly describing the same fee at different levels of completeness — before or after the per-order charge, on the item or on item plus shipping, in one category or another. Etsy's headline is lower and its stack has four parts.
eBay 13.6% + $0.30/$0.40 (eBay) · Etsy 6.5% + processing + $0.20 + Offsite Ads
11 minSix published sources give six different ocean freight rates. The mode decision is still easy.
LCL is quoted between $80 and $400 per cubic meter depending on who you ask. Air runs $4 to $12 per kg. The rates move constantly — but the thresholds that decide which mode to use barely move at all.
Under 2 CBM air · 2–15 LCL · above 15 FCL
11 minA Vendor Central invitation feels like a promotion. brands being purged from the program.
1P vendors are at 10% to 18% net margin against 25% to 35% for 3P, with tightening chargebacks and an expanding unprofitable-item list. The invite is worth modeling before it is worth accepting.
Reported net margin: 1P 10–18% · 3P 25–35%
9 minAdding a second marketplace means your price stops being a per-channel decision
Walmart requires your price there to be no higher than elsewhere, including your own site. Amazon checks your price against other retailers and can suppress the Buy Box over it. Two policies pointing at each other, and one price to satisfy both.
One price, two policies pointing at each other
10 minYour second marketplace is a decision about traffic cost, not about fees
Walmart charges less and sends less traffic. TikTok's platform fee is the lowest and its acquisition cost is the highest. Once you look past the referral rate, the four candidates separate cleanly — and one of them is not a marketplace at all.
Compare acquisition cost, not referral rate
11 minTikTok told sellers their own shipping was ending, then withdrew it. Half the articles online never noticed.
The headline referral fee was 6% until August 4, 2026 and is 8% now — still the lowest of any major US marketplace. The effective rate on an affiliate-driven sale runs 20% to 30%. And the biggest operational question of 2026 has a settled answer: Seller Shipping survived, because TikTok withdrew the mandate on February 17.
8% headline since Aug 4 (6% before) · 20–30%+ effective on affiliate sales
11 minWalmart's storage costs about the same as Amazon's in March and a third of it in November
The off-peak difference is at three cents per cubic foot. In Q4 Amazon roughly triples and Walmart does not — and there is no aged-inventory surcharge stack. That is where the comparison is actually decided.
Q4 storage: Amazon $2.40 vs Walmart $1.50 per cu ft
9 minYour listing disappeared. Here are the nine reasons, in the order to check them.
A suppressed listing does not rank, does not convert and does not appear in search. Amazon rarely explains which rule you broke — but the causes are a short, checkable list, and most of them are covered in detail elsewhere on this site.
Nine causes · check in this order
9 minThe one element Amazon will hide your entire listing over
A main image on an off-white background does not get a warning. The listing stops appearing in search until it is fixed — and compliance sweeps suppressing listings that ran fine for weeks.
Pure white RGB 255,255,255 · 85% frame fill
11 minA 6% flat fee is not 6%. On a short repayment it is 18% to 36% a year.
Amazon Lending is now entirely third-party and invite-only with no published eligibility. The products offered price themselves in flat fees and factor rates, which are not comparable to an interest rate unless you convert them — and almost nobody does.
Convert every flat fee to an annualised rate before comparing
11 minSeller Fulfilled Prime is not a shipping setting. It is a six-day operating week with a weekly exam.
Amazon raised the delivery-speed thresholds again on July 6, 2026. The program requires weekend fulfillment, 93.5% on-time delivery, and performance is reviewed weekly — with three trial attempts per calendar year if you fail.
Speed thresholds raised again on July 6, 2026
10 minBundling changes six numbers at once, and most sellers check one
A multipack raises the unit price, which moves the fulfillment fee band. It changes the dimensions, which moves the size tier and every storage layer. It needs its own barcode, its own prep and its own review pool. The fee saving is real — it is just not the only thing that moved.
One decision, six moving numbers
10 minIf your IPI dropped in the spring evaluation, you cannot stock for Black Friday now
Capacity limits are set from a quarterly evaluation. A score that fell in the April to June window restricts your Q3 inbound — which is the window you need to fill for peak. And published thresholds disagree.
Threshold 400 (Amazon) · manage to 500+
10 minEvery published estimate of what you are owed comes from a company that wants a share of it
Reimbursement recovery services charge a percentage of what they recover. The figures they publish about how much you are losing are marketing for that percentage. Here is how to work out whether you need one, from your own reports.
Decide from your own reimbursement report, not theirs
10 minNine reports decide almost everything on this site. Most sellers open two of them.
Every guide here ends with the same instruction in different words: get the number from your own account rather than from an article. These are the nine reports those numbers come from, and what each one settles.
Nine reports · one weekly routine
10 minThere is a second set of buyers on the same listings, and switching them on is free
Amazon Business is an opt-in feature layer on your existing account, not a separate one. Figures: business buyers convert at three times the rate, order 74% more units, and return 42% less often.
No extra fee · 3× conversion, 42% fewer returns
9 minEvery dated change that hit US marketplace sellers in 2026, in one place
Twenty dated changes landed within thirteen months, from three different sources — Amazon, CBP and Congress. Several of them interact. This is the timeline, with what each one costs and where the detail sits.
Twenty dated changes, September 2025 to October 2026
11 minOn March 31, 2026 Amazon ended commingled inventory. Brand owners stopped stickering; everyone else started.
One change split the seller base in two. Brand Registry brand owners can now use their GS1 barcodes as the tracking identifier. Resellers must apply an FNSKU to every unit — and Amazon stopped doing that for them on January 1.
31 Mar 2026: commingling ends, FNSKU mandatory for resellers
11 minMost launch checklists are in the wrong order. Here is the sequence, with the deadlines that are not yours to move.
Half the work of launching a product has a lead time set by somebody else — a trademark takes months, VAT registration takes weeks, third-party testing takes longer than you think. Sequencing around those is the whole exercise.
Order it by lead time, not by enthusiasm
10 minYou can list in Canada and Mexico without shipping anything there. The catch is in the fee and the delivery time.
Remote Fulfillment with FBA puts your US inventory on Amazon.ca and Amazon.com.mx without cross-border logistics. Reported delivery times are 7 to 12 days for Canada, the fee replaces the FBA fee and is higher — and the customer pays the duty.
One inventory pool, three (now four) marketplaces
11 minAmazon credits you roughly 10% for bringing your own traffic. Most brands never claim it.
The Brand Referral Bonus credits part of the referral fee back when tagged external traffic — Google, Meta, email, creators — converts on Amazon. The average is around 10%, the range runs from about 5% to as high as 30% by category, and the whole thing hinges on one mechanical detail: the Attribution tag.
≈10% average credit on tagged external sales
12 minShipping Shopify orders from FBA stock: MCF's fee table, and the January increase nobody priced in
Multi-Channel Fulfillment lets the inventory already sitting in FBA ship your Shopify, eBay and Walmart orders. The January 2026 increase hit single-unit MCF orders four to five times harder than FBA's own base increase, and a 3.5% fuel surcharge landed on top in May. The convenience is real; so is the drift in what it costs.
+$0.35–$0.41 per single unit in January, +3.5% surcharge in May
12 minOne campaign with every keyword in it is how launches die. The four-campaign minimum, explained.
The consensus is blunt: auto, broad, phrase and exact each get their own campaign, converting search terms flow one way through them, and negative keywords are the plumbing that stops the campaigns bidding against each other. Skipping the plumbing means paying more for the same click.
Search-term pruning: 15–25% less wasted spend (agency data)
10 minSubscribe & Save discounts come out of your margin — on the first order and every reorder after it
The 0%, 5% or 10% base discount is seller-funded on every subscription shipment, and referral and FBA fees are charged on the discounted price. The extra 5% that makes 'up to 15%' is Amazon's money. Whether the trade works is a comparison against your ad cost per order, not against zero.
5–10% seller-funded on every subscription order — Amazon
10 minBrands gate their products to keep sellers like you out. Becoming authorized is the route almost nobody tries.
Wholesale sellers spend months collecting invoices to satisfy an ungating form. The document those systems are actually looking for — a supply relationship the brand permits — can be requested directly from the brand, and rarely is.
Authorization is a relationship, not a document
10 minAmazon says its currency conversion costs 0.75% to 2%. Everyone selling an alternative says 3% to 4%.
This is the clearest example on this site of a figure where the primary source and the secondary sources disagree — and where every secondary source has something to sell. Here is how to measure your own rate instead.
ACCS: 0.75–2.0% stated · 3–4% claimed
10 minA Prime Day deal costs $100 before a single unit sells, then 1.5% of everything that does
Deal participation stopped being a margin-neutral traffic tool. Best Deals, Lightning Deals and Prime Exclusive Discounts carry an upfront fee plus a variable percentage — and a 60-day lowest-price rule that constrains what you can even offer.
$100 upfront + 1.5% of promotional sales, capped $5,000
9 minThere is a second peak fee, and it is not storage. Fulfillment costs more from October 15 too.
Amazon confirmed the 2026 holiday peak fulfillment fee on July 7: October 15, 2026 to January 14, 2027, averaging $0.32 per unit over non-peak, across FBA, Remote Fulfillment, MCF and Buy with Prime, with the 3.5% surcharge on top. The window, the stack, and the inbound deadlines that come with it.
Peak fulfillment: +$0.32/unit avg, 15 Oct 2026 – 14 Jan 2027 — Amazon
10 minOne number can suspend your account on its own. Amazon tells you about it after it is too late.
Order Defect Rate rolls negative feedback, A-to-z claims and chargebacks into one percentage on a 60-day window. The published threshold is 1%. the alert arrives after you cross it, not while you are heading there.
ODR threshold 1% · top sellers hold below 0.3%
10 minAmazon stopped prepping your inventory on January 1, 2026. Somebody still has to do it.
FBA prep and labeling services ended in the US. The work did not disappear — it moved to you, your supplier, or a prep center charging a reported $0.35 to $2.00 per unit. Most sellers discovered this when a shipment was rejected.
Prep: $0.35–$2.00/unit at prep centers (vendor ranges) · inbound defect fee ~$0.60/unit avg (Amazon)
10 minA+ Content is free, gated behind a trademark, and found in vendor studies to lift conversion by 3% to 10%
Brand Registry unlocks eight tools and sellers typically use two. Conversion is the dominant ranking signal, which makes the enhanced content modules the highest-use free thing available to a registered brand.
Reported A+ conversion lift: 3–10%
12 minSix sources give six different prices for AWD storage. The cheapest one is not the answer anyway.
AWD storage is anywhere between $0.43 and $0.75 per cubic foot depending on region, program and who is publishing. But storage is a fraction of the cost, and the fees that decide this comparison are the ones underneath it.
AWD storage: $0.43–$0.78/cu ft (published range) — transport and prep decide it
11 minBrand Registry is free. The trademark it requires is not, and one vendor estimates about two thirds of first applications are rejected.
Enrollment costs nothing and takes minutes. Getting to the point of enrolling means a trademark at $350 per class in USPTO fees (since January 18, 2025) plus attorney costs, and eight to fourteen months — unless you take the pending-application route.
Enrollment free; USPTO $350/class + attorney $300–$1,000
11 minFBA fees have risen 25% to 35% since 2020. At some point self-fulfillment stops being the worse option.
The question is not whether FBA is expensive. It is where the crossover sits for a specific SKU — and three 2026 changes moved it: the fee increase, the surcharge, and Amazon ending prep services.
Cumulative FBA increases: 25–35% since 2020
11 minAnything with a lithium battery is a dangerous good. That includes most of what you sell.
The hazmat net catches far more than chemicals: anything containing a lithium cell, pressurised, flammable, chemically reactive or strongly magnetic can enter review. While it is in the queue you cannot send inventory, and stock already at a center can be held.
Review: 2–5 business days, inbound blocked
9 minCross $10,000 a month for three months and Amazon requires you to be insured
The threshold is $10,000 in sales across three consecutive months, and the requirement is $1 million per occurrence with $2 million aggregate, naming Amazon as an additional insured. Non-compliance will lead to suspension.
$1M per occurrence / $2M aggregate
10 minOne document decides six separate outcomes. Most sellers never ask for it properly.
The supplier invoice is what Amazon reimburses against, what an appeal turns on, what ungating tests, what customs values, what a buyer reconciles, and what your accounts are built from. Six systems, one piece of paper, and it can only be obtained at purchase.
Six systems, one document, one moment to get it
11 minUngating is an invoice test disguised as a category application
Amazon gates at three levels — category, brand and individual ASIN — and clearing one does not clear the others. Almost every rejection traces back to the same document: an invoice that was not from an authorized distributor, or did not match the account exactly.
Invoice: authorized distributor, 10+ units, 90–180 days
11 minFrom July 8, 2026, CPSC certificates are filed electronically at the border. That changes who finds out first.
Importers of most regulated consumer products now eFile certificates of compliance with CBP through a Partner Government Agency message set. A missing certificate stops being a Seller Central problem and becomes a customs problem.
CPSC eFile at the border from July 8, 2026
11 minYour profit and loss says March was terrible and June was excellent. Both are wrong.
Cash accounting books a container of inventory the month you pay for it and the resulting sales across the six months after. The margin swings that produces are not real, and every decision you make from them is made on noise.
Cash accounting: cost and revenue in different months
12 minAmazon never confirmed an algorithm called A10. A great deal of listing advice is built on it anyway.
The seller community named the evolved search system A10. Amazon calls its search algorithm A9. Underneath the naming argument the observable shift is real — and it moved weight from keywords toward whether shoppers actually buy.
Titles: 75 characters since July 27, 2026 · backend terms: 249 bytes
11 minBeing Amazon-only is priced as a risk by the people who buy businesses. It is also a ranking disadvantage.
Buyers discount platform concentration explicitly. Amazon's own search system treats external traffic as a ranking signal. The same decision that makes your business more valuable also makes your listings rank better — which is unusual.
External traffic: 15–20% ranking contribution
12 minAmazon collects your sales tax. That does not mean you have no tax obligations.
All 45 sales-tax states plus DC have marketplace facilitator laws, so Amazon collects and remits on your FBA orders. What it does not do is remove nexus — and FBA inventory creates physical nexus in every state where a pallet of your stock sits.
Marketplace laws cover sales tax only
13 minThe aggregator era ended. Broker data puts multiples down 30% to 40%, and the buyers who remain read your books.
Thrasio filed Chapter 11. Perch was absorbed. Several Berlin aggregators wound down. What replaced them is a disciplined buyer pool paying multiples of roughly 2.5x to 4x SDE — and running diligence that finds what your accounting hides.
Reported: 2.5x–4x SDE, down from 4x–6x in 2021
12 minPublished Amazon ad benchmarks disagree by 8 points on ACOS. Here is how to read them anyway.
One managed portfolio reports a 38% median ACOS. Another puts healthy at 30–32%. Both are true, because they measure different things. The number that actually decides whether you can afford to advertise is your own margin.
Median ACOS 38% per account, 30% spend-weighted
11 minThe cheapest offer usually loses the Buy Box. Here is what actually decides it.
Amazon compares landed price, not sticker price, and repricer analyses put the tolerance at roughly 5% of the lowest qualified offer. Fulfillment speed and seller health now carry comparable weight — which is why an FBA offer can price above an FBM one and still win.
Tolerance: ~5% of the lowest landed price
11 minFour of your costs rise in Q4 at once, and one of them is your own cash
Storage roughly triples. Agency data puts the CPC spike at 60% to 80%. Aged inventory keeps ageing. And DD+7 means the revenue funding all of it arrives two to four weeks after the sale. Peak season is a liquidity event before it is a sales event.
Decide by September 30, not in November
10 minRoughly one in five FBA shipments arrives short. Amazon will not tell you which one.
Inbound discrepancies are not automatically investigated or automatically reimbursed. You find them, you file them, and you do it inside a claim window that published sources put at anywhere from 60 days to nine months.
Claim window: 15–60 days from delivery (Amazon) · you find them, not Amazon
10 minOn February 12, 2026 your variation family stopped sharing one review count
Reviews used to pool from every child ASIN up to the parent, so one color's reviews lifted all of them. Amazon ended that for variations it judges to have significant feature differences — which changes how a catalog should be structured.
Separate review pools by feature difference
11 minVine costs more than the enrollment fee, and you only get one attempt per ASIN
The fee is at $0 to $200. The real cost is the free units, their fulfillment, and the fact that enrollment is once per ASIN for life — including any variation of the parent. A bad product enrolled early buys permanent, detailed criticism.
One enrollment per ASIN, for its lifetime
12 minYour account is deactivated. The first thing to do is nothing, for 24 hours.
Amazon's enforcement now flags accounts before a human reviews them, and the system treats panic appeals as low quality. Diagnosing which deactivation you have — and which review team reads it — decides everything that follows.
Funds held 90 days; appeal window 90 days
11 minAmazon changed when you get paid, and did not send an announcement. Most sellers found out from their bank balance.
From March 12, 2026 the Delivery Date Based Reserve holds your money for seven days after the customer receives the order — not after you ship. Combined with the disbursement cycle, FBA sellers at 14 to 27 days from sale to deposit.
Sale to bank: 14–27 days FBA, 20–35 FBM
10 minAn intellectual property complaint is not an Amazon problem. It is a problem with the person who filed it.
Appealing an IP complaint to Amazon asks a platform to overrule a rights owner it has no reason to doubt. Getting the complaint withdrawn removes the basis for the action entirely — and reporting suggests it works faster.
A retraction removes the basis; an appeal argues about it
11 minA return costs you three times: the refund, the fee, and a badge on your listing
The refund is the obvious loss. The returns processing fee arrives three months later. And once a SKU crosses its category threshold, Amazon can label the listing itself — which one agency reports knocking 20% to 50% off conversion.
Returns fee charged in the 3rd month after shipment
9 minAmazon puts your box in another box, and charges you for it. There is a program that stops this.
Ships in Product Packaging lets qualifying items ship in their own packaging with no Amazon over-box. Enrollment requires passing a durability standard — and one published estimate puts the saving at over $180,000 a year for a seller moving 10,000 bulky units a month.
Bulky base fees fell in 2026 — but only with SIPP
10 minCBP can open your container, and you pay for it. Here is what each type of exam costs.
Under 19 USC 1467 customs may examine any shipment, and the importer bears the cost. An X-ray runs a few hundred dollars. An intensive exam runs into the thousands, before demurrage. Selection is no longer random.
Intensive exam: $500 to $2,500+, plus demurrage
9 minRelease from manifest is gone. Your parcels now need a customs entry, and there are two of them.
Entry Type 86 let low-value parcels clear duty-free with minimal data. ACE now rejects those filings. Every shipment needs Type 11 or Type 01 — and the choice between them changes your fees, your bond and your broker bill.
Type 86 → Type 11 or Type 01
12 minSelling into Europe is a compliance project, not a listing translation
Amazon runs more than twenty marketplaces and copying your listings across takes an afternoon. What takes months is VAT registration where you store stock, EPR registration before your listings go live, and a packaging regulation that applied from August 12, 2026.
Pan-EU FBA: 5 VAT registrations from Jan 2026
8 minAmazon announced a $0.08 fee increase for 2026. Then it added 3.5% on top of every fulfillment fee.
Since April 17, 2026 a 3.5% fuel and logistics-related surcharge applies to every US and Canada FBA fulfillment fee; MCF and Buy with Prime followed on May 2. Amazon puts the average at $0.17 per unit, with no end date. The mechanics, the compounding, and where to read your own figure.
3.5% of the fulfillment fee — avg $0.17/unit — since 17 Apr 2026
9 minAmazon now reimburses at your cost, not your price. The published loss figures disagree by a factor of two.
Since March 31, 2025 Amazon has paid out on sourcing cost for inventory lost before a customer orders. Vendor estimates of the damage range from 40% to over 75% — and almost every one is published by a company that sells reimbursement software.
Reimbursement basis: sale price → sourcing cost
12 minAmazon storage is four separate charges, and three of them can land on the same box
Base rate ($0.78 standard, $2.40 in Q4), aged-inventory surcharge from day 181 with a new 15-month tier in 2026, and a utilization surcharge above 22 weeks of cover. They stack. Here is the 2026 rate card, the reports to pull, and the arithmetic on one box.
Standard: $0.78/cu ft Jan–Sep, $2.40 Oct–Dec — unchanged for 2026
8 minThe ten-digit number you are legally responsible for, even when your broker picks it
Every product you import needs an HTS code, and it sets your duty rate. Under US law the importer of record carries the duty of reasonable care — and that duty cannot be delegated to the broker who chose the code.
Liability sits with the importer, not the broker
9 minAvoiding the inbound placement fee costs you freight. Here is where the two lines cross.
Amazon-optimized splits carry no placement fee but need five or more cartons per SKU and five freight legs. Minimal splits cost a per-unit fee that rose ~$0.05 on January 15, 2026. The crossover formula, the 2026 structure, and the Seller Central path.
Optimized split: $0/unit. Minimal split: per-unit fee by size, weight and region
10 minThree letters on a quotation decide who pays the tariff. Most sellers never read them.
EXW, FOB and DDP look like shipping jargon sitting next to the price. They determine who clears customs, who carries the tariff risk, and whose name goes on the entry — which is the name CBP holds responsible.
DDP is the only term making the seller importer of record
9 minFour published sources, four different values for the same customs fee. Here is how to build a landed cost anyway.
Duty is the line everyone models. The user fees underneath it — MPF, HMF, bond, broker, ISF — are where landed cost quietly grows. And the published rate cards for those fees do not agree with each other.
Informal MPF: $1.16 / $2.49 / $2.69 / $2.72
9 minAmazon's low-inventory-level fee: the 28-day rule, the 2026 FNSKU change, and a reorder trigger that survives both
The threshold is 28 historical days of supply on both the 30-day and 90-day windows — Amazon's own figure, not a blog's. Since January 15, 2026 it is measured per FNSKU and reaches bulky items. Here is where to read it in Seller Central and how to set the reorder point.
Threshold: 28 days (30-day AND 90-day windows) — Amazon
11 minYour selling price now sets your fulfillment fee. Your repricer does not know that.
Since January 2026 Amazon calculates the FBA fulfillment fee partly from your price band. Raise a $49 item to $52 and you can cross a boundary, take a larger fee, and take a larger surcharge on that larger fee — while your repricer still models fulfillment as a constant.
Price is now an input to the fulfillment fee
12 minSix product research mistakes, priced. Not opinions — arithmetic from the current fee schedule.
Most product research advice is a list of things to avoid with no number attached. Every mistake below has a cost you can calculate from published 2026 rates, and most of them are made before the first purchase order is signed.
Every error below has a number attached
10 minWhen pulling stock out of Amazon is cheaper than leaving it there
Removal costs about a dollar a unit and feels like admitting defeat. Holding costs a rate per cubic foot every month, on four stacked charges, on a unit that is not selling. Here is the arithmetic that decides it.
Removal: ~$1–2/unit once (rate card) vs holding every month from day 181
11 minThe badge on the supplier's profile means they paid for it. Here is what actually verifies a factory.
Gold Supplier is a paid advertising package. Verified Supplier is a light-touch check. Neither tells you the bank account you are about to wire to belongs to the company you think you are buying from — and since March 2025, a supplier who cannot issue a proper invoice also costs you your Amazon reimbursements.
Reported: 12% of new listings are scams or fake factories
9 minAmazon's 2026 US fee changes: the $0.08 headline, and the seven other changes it did not mention
Fulfillment fees rose ~$0.08 per unit on January 15, 2026. The same cycle ended FBA prep, moved the low-inventory fee to FNSKU level, added a 15-month aged tier, delayed payouts to DD+7 from March 12 and layered a 3.5% fuel surcharge from April 17. The full calendar, sourced.
+$0.08/unit average (Amazon) + 3.5% fuel surcharge from 17 Apr 2026
11 minThe $800 de minimis exemption is gone. Here is what a low-value import costs now.
Section 321 was suspended for China in May 2025, extended worldwide that August, and written into regulation in June 2026. What changed, what sellers pay, and which business models stopped working.
