Amazon Is Moving Your ASINs to New Fee Categories on Oct 31
Amazon is reassigning certain ASINs to new referral-fee categories effective October 31, 2026, according to a report from beBOLD Digital published October 13. The referral fee percentages aren’t changing — but which percentage applies to your products might be. If one of your ASINs lands in a different category, your per-unit referral fee changes overnight, right as Q4 selling season hits full stride.
Here’s the direct answer: pull every affected ASIN’s current fee category and percentage from Seller Central now, model the margin impact per SKU, and dispute any misclassification before October 31 — because once the switch flips, wrong assignments quietly tax every sale until you catch them.
This matters more than most fee news because it’s silent. Amazon isn’t raising rates, so there’s no headline number to argue with. The money moves in the background, inside the category logic on your product detail pages. And on Amazon, a 7-percentage-point swing in referral fee on a mid-priced product can erase your entire advertising margin. This guide walks you through exactly what changed, how to audit your catalog in an afternoon, and what to do before and after the deadline.
What Amazon Is Actually Changing (and What It’s Not)
Let’s get the facts straight so you don’t overreact or underreact.
What it is: Amazon is reassigning some ASINs from their current fee category to a new one, effective October 31, 2026. Every ASIN on Amazon belongs to exactly one fee category, and that category determines the referral fee percentage Amazon takes from each sale.
What it isn’t: This is not a fee increase. The percentages themselves stay the same. The change is about assignment — which products fall into which bucket.
Why that distinction matters: A fee category is not the same thing as the browse category your customers see. Your product can sit in the same storefront category it always has, look identical on the detail page, and still carry a different fee category behind the scenes. Amazon also uses fee categories for more than just referral fees — closing fees, FBA fulfillment fees, FBA returns processing fees, and other fee types can all key off the same classification. So a reassignment can touch several cost lines at once.
Who’s affected: Amazon notified affected sellers, but don’t assume you’re safe just because your listings look normal. If you haven’t received a notice, you may genuinely be unaffected — or the notice may be sitting unread in your Performance Notifications. Check.
The 2026 Referral Fee Numbers That Matter Here
To model impact, you need the real 2026 referral fee schedule. The table below reflects Amazon’s published US fee schedule (cross-checked against Amazon’s official schedule in July 2026):
| Category | 2026 referral fee | Minimum per item |
|---|---|---|
| Most general categories (Home & Kitchen, Toys & Games, Sports & Outdoors, Office Products, Pet Supplies) | 15% | $0.30 |
| Consumer Electronics, Computers, Video Game Consoles | 8% | $0.30 |
| Electronics Accessories | 15% up to $100; 8% on the portion above | $0.30 |
| Beauty, Health & Personal Care | 8% if total ≤ $10; 15% if above | $0.30 |
| Baby Products | 8% if total ≤ $10; 15% if above | $0.30 |
| Clothing & Accessories | 5% ≤ $15; 10% $15–$20; 17% above $20 | $0.30 |
| Automotive & Powersports | 12% | $0.30 |
| Jewelry | 20% up to $250; 5% on the portion above | $0.30 |
| Watches | 16% up to $1,500; 3% on the portion above | $0.30 |
| Amazon Device Accessories | 45% | $0.30 |
| Books, Music, Video, Software | 15% + $1.80 closing fee | — |
Look at the gaps between neighbors. Consumer Electronics pays 8% while Electronics Accessories pays 15% up to $100 — that’s a 7-point spread between two categories that routinely get confused. A $25 gadget moved from one to the other pays either $2.00 or $3.75 per sale. That’s the whole story of why this audit matters: reassignments that cross these boundaries quietly reprice your entire unit economics.
The table above covers referral fees only. For the rest of the 2026 fee stack — fuel surcharges, peak fulfillment fees, storage, and the seller math that ties them together — see our 2026 FBA fee breakdown.
How a Fee Category Change Rewrites Your Ad Math
Here’s the part most sellers miss. The referral fee doesn’t just take money — it sets your advertising ceiling.
Your break-even ACoS (advertising cost of sale) equals your contribution margin percentage: the money left after COGS, Amazon fees, and fulfillment, divided by price. When the referral fee moves, the ceiling moves, and every PPC campaign you’ve tuned to the old ceiling needs recalibrating.
Worked example (illustrative — real 2026 fee percentages)
Say you sell a $29.99 phone stand. Your landed COGS is $7.50 and your FBA fulfillment fee is $4.08 per unit.
Scenario A — currently in Consumer Electronics (8%):
– Referral fee: $29.99 × 8% = $2.40
– Contribution: $29.99 − $7.50 − $4.08 − $2.40 = $16.01
– Margin: 53.4% → break-even ACoS ≈ 53.4%
Scenario B — reassigned to Electronics Accessories (15%):
– Referral fee: $29.99 × 15% = $4.50
– Contribution: $29.99 − $7.50 − $4.08 − $4.50 = $13.91
– Margin: 46.4% → break-even ACoS ≈ 46.4%
That’s a 7-point drop in your allowable ACoS. If your campaigns were tuned to run at 50% ACoS — comfortably profitable under the 8% fee — they’d be losing money on every sale under the 15% fee. You’d need to cut bids, raise the price, or both. And if the reassignment goes the other direction, you’ve got headroom you should be spending — otherwise you’re leaving Q4 sales on the table.
One more quick one: on a $24.99 item moving from 8% to 15%, the fee jumps from $2.00 to $3.75 — an extra $1.75 per unit. At 500 units a month, that’s $875 a month evaporating. For a product doing 2,000 units in December, it’s $3,500 in a single month.
The ASIN Audit Workflow: Find Your Exposure in an Afternoon
Don’t audit by sales volume. Audit by margin impact. A slow SKU with a big fee swing can hurt more than a bestseller that stays put. Here’s the workflow, in order.
Step 1: Pull your affected ASIN list
Check Performance Notifications in Seller Central for Amazon’s notice about the October 31 reassignment. The notice should identify affected ASINs and their proposed new categories. If you received nothing, you’re probably clear — but confirm by checking your fee categories directly rather than assuming.
Step 2: Record current category and rate for every ASIN
For each ASIN in your catalog (prioritize the affected ones, but spot-check the rest):
- Open the listing and confirm the fee category Amazon currently assigns. Amazon states every ASIN belongs to exactly one fee category — find yours in the listing’s classification details or through the Revenue Calculator.
- Note the referral fee percentage and any per-item minimum from the 2026 schedule above.
- Run Amazon’s Revenue Calculator and the Fee and Economics Preview report in Seller Central for each affected ASIN — Amazon itself pointed sellers to these tools for modeling fee impacts in its 2026 fee announcement.
Step 3: Rank ASINs by dollar impact, not revenue
For each affected ASIN, calculate:
(New fee % − Old fee %) × selling price × estimated monthly units
Sort descending. The top of that list is your audit priority. A handful of SKUs usually carry 80% of the dollar exposure.
Step 4: Verify each proposed classification against reality
For every ASIN on your impact list, ask: is the proposed category actually correct for what this product is? Check Amazon’s category guidelines for the proposed category. Boundary cases — accessories that function as standalone devices, multi-use products, bundles — are where misclassifications cluster. Document your evidence (product title, bullet points, primary function, customer-facing category) so it’s ready if you need to dispute.
Step 5: Dispute before the deadline
If a proposed reassignment is wrong, open a case with Selling Partner Support before October 31. The dispute process: pull your transaction-level fee evidence from Reports > Payments > Transaction View, compare against the fee schedule for the correct category, and submit transaction dates, amounts charged, the correct fee you believe applies, and the category guidelines that support it. File claims only with complete documentation — submitting invalid claims can prevent future disputes.
Two policy realities to know going in:
– Amazon generally reimburses referral fee differences only for transactions within the last 90 days once a category is corrected — so the clock matters twice: before the switch for the dispute, and after it for catching anything that slipped through.
– Sellers are responsible for identifying and reaching out to Amazon to review categorization — Amazon’s own support documentation puts this squarely on you, and the internal categorization team makes the final call. Come armed with evidence, not opinions.
Your Before/After Oct 31 Checklist
Before October 31
- [ ] Read your Performance Notifications for the reassignment notice and export the affected ASIN list.
- [ ] Record each affected ASIN’s current fee category and referral fee percentage.
- [ ] Run the Revenue Calculator / Fee and Economics Preview for every affected ASIN and save the output (screenshot or export) as your baseline.
- [ ] Compute the dollar impact per ASIN: fee difference × price × monthly units. Rank and prioritize.
- [ ] Verify each proposed classification against Amazon’s category guidelines; gather evidence for any that look wrong.
- [ ] File disputes with Selling Partner Support for clearly wrong assignments — complete documentation, one claim per charge.
- [ ] For confirmed changes, recalculate break-even ACoS per ASIN and adjust PPC bids and budgets now, not in December.
- [ ] Revisit pricing: a confirmed fee increase may justify a price bump before the holiday rush (watch your Buy Box elasticity); a decrease may justify more aggressive holiday bids.
- [ ] If you use repricers or third-party margin tools, update the fee assumptions feeding them.
After October 31
- [ ] Spot-check the first sales of each affected ASIN in Payments > Transaction View — confirm the applied referral fee percentage matches the intended category.
- [ ] Re-run the Revenue Calculator for affected ASINs to confirm the live numbers.
- [ ] For any ASIN that landed in the wrong category despite your dispute (or that you missed), file a correction case immediately — and remember the 90-day reimbursement window.
- [ ] Reconcile your Q4 P&L against your pre-October 31 baseline so fee drift shows up as its own line, not as mysterious margin compression.
- [ ] Keep your baseline export. If Amazon’s classification teams revisit categories later, you’ll want proof of what changed and when.
The Bigger Pattern: Marketplaces Are Repricing Ahead of the Holidays
This isn’t happening in a vacuum. TikTok Shop Malaysia just ran its own fee recalibration with the same October 31 effective date — marketplaces are tightening their economics right before Black Friday and the Q4 peak, when volume is highest and sellers are least likely to scrutinize fee lines. (We ran the Q4 numbers on TikTok Shop separately — see our TikTok Shop fee breakdown.)
The lesson for US Amazon sellers: October is fee-audit season. Every year brings some fee change effective right around now — 2026’s version just happens to be invisible rather than announced with a rate table. If you haven’t already modeled the 2026 FBA fee changes against your catalog, pair this audit with our 2026 FBA fee breakdown so your Q4 margins reflect every fee line, not just this one. The sellers who treat the last two weeks of October as a fee audit window will enter Q4 with clean margins; everyone else will discover the damage in their January P&L, when it’s too late to fix.
Quick note: this is general guidance about Amazon’s fee mechanics, not professional financial or legal advice. Amazon’s fee pages and your own Seller Central data are the final authority — fee schedules can change, so confirm your category’s current rate before repricing.
Frequently Asked Questions
What is the Amazon ASIN fee category reassignment on October 31, 2026?
Amazon is reassigning certain ASINs to new referral-fee categories effective October 31, 2026. The referral fee percentages themselves are not changing — but the category each affected ASIN belongs to (and therefore which percentage it pays) may change. The change was reported by beBOLD Digital on October 13, 2026, based on Amazon’s notifications to affected sellers.
How do I know if my ASINs are affected?
Check Performance Notifications in Seller Central for Amazon’s notice, which should identify affected ASINs and their proposed new categories. Even without a notice, you can verify any ASIN’s current fee category through its listing classification details and model fees with Amazon’s Revenue Calculator and Fee and Economics Preview report.
Is the fee category the same as my product’s browse category?
No. Your product’s browse (storefront) category is what customers see. The fee category is a separate, single classification Amazon assigns to every ASIN and uses to calculate referral fees — and potentially closing fees, FBA fulfillment fees, and FBA returns processing fees. Your listings can look completely unchanged while the fee category behind them moves.
How much money can a reassignment actually cost?
It depends on the category spread. A $29.99 product moving from Consumer Electronics (8%) to Electronics Accessories (15%) pays $2.10 more per sale — and its break-even advertising ACoS drops by about 7 points. At 500 units a month, a 7-point fee swing on a $25 item costs roughly $875 a month. Always compute impact as fee difference × price × units for each ASIN.
Can I dispute a fee category reassignment?
Yes. If you believe the assigned category is wrong, open a case with Selling Partner Support before the reassignment takes effect. Provide transaction dates, the fee charged, the correct fee you believe applies, and the category guidelines supporting your case. Amazon’s internal categorization team makes the final decision, and only one claim is allowed per charge — so file with complete documentation.
What if I discover a misclassification after October 31?
File a correction case immediately. Once Amazon agrees the category was wrong, it generally reimburses the referral fee difference only for transactions within the last 90 days — so catching it quickly is worth real money. Keep your pre-October 31 Revenue Calculator baselines as evidence of what changed.
