6 New Amazon Policies Hitting US Sellers in October 2026

Six Amazon policy changes land on US sellers this October — and they arrive in the worst possible month, stacked against Black Friday prep when nobody is reading Seller Central notifications.

Two carry suspension risk. One applies only to sellers in mainland China. All six have hard dates. Here is each one, what it actually requires, and what to do about it.

Quick reference

1. Q4 peak fulfillment fee

Effective October 15, 2026 through January 14, 2027. Applies to FBA, Remote Fulfillment with FBA, Multi-Channel Fulfillment and Buy with Prime.

Amazon's framing is that the average per-unit increase matches last year's. The important qualifier is that the peak fee's share is magnified for low-priced and small, light items — a flat per-unit addition is a rounding error on a $60 product and a serious problem on an $8 one.

What to do: rebuild unit economics on every sub-$15 ASIN, then recalculate break-even ACoS. Peak fees cut contribution margin, and break-even ACoS moves with it — so campaign targets set in September are now too high.

2. BFCM inbound cutoffs

Four dates, and the distinction between them matters:

• Oct 14 — AWD cutoff
• Oct 17 — Deal inventory must arrive, or deal eligibility may be cancelled
• Oct 21 — FBA, minimal shipment splits
• Oct 28 — FBA, Amazon-optimized splits (the option most sellers use)

The trap: inventory must be "inbound completed" by the cutoff, not merely shipped. A truck still in transit on October 28 has missed the deadline. Amazon's own guidance is to allow two to three weeks of buffer, which means the real planning date was earlier than the published one.

What to do: check receive status, not ship status, today. If you secured a deal and your deal inventory missed October 17, assume eligibility is at risk and plan a coupon fallback.

3. Dangerous goods compliance questions — suspension risk

Effective October 26, 2026. Creating or editing a listing in designated categories now requires answering new questions that determine whether Amazon classifies your product as dangerous goods.

Affected categories:

• Beauty and personal care
• Household cleaning
• Automotive
• Tools
• Consumer electronics — especially anything with a lithium battery

Wrong answers can trigger a review and listing suspension. That is the real exposure here: a routine listing edit in late November — a title tweak, a bullet update for gifting season — can suspend an ASIN in your highest-traffic week.

What to do: upload missing Safety Data Sheets now, and freeze non-essential listing edits in affected categories through BFCM. If you must edit, do it before the event, not during it.

4. Expanded bundling rules

Took effect September 30, with October as the main enforcement period.

Bundles in most categories — not just consumer categories any more — must use original manufacturer or brand packaging configurations. You can no longer combine single items into your own bundle pack.

This is a genuine strategy change, not a paperwork one. Seller-created multipacks have been a standard differentiation and price-band play for years. That route is closing across far more of the catalogue than before.

What to do: audit every bundle ASIN against the new standard before the enforcement wave reaches you. A bundle pulled in November costs you the listing, the reviews attached to it and the Q4 revenue.

5. B2B self-fulfilment delivery standard — suspension risk

The metric started September 30. Suspension risk begins October 30.

Self-fulfilled shipments to Amazon Business customers must be delivered during business hours at a rate of at least 90%. Fall below it and non-compliant offers to business buyers may be suspended.

The detail that catches people out: weekend and holiday deliveries do not count toward the metric. A carrier that cheerfully delivers on Saturday is not helping you — it is simply not counted.

What to do: if you are FBM and sell to Amazon Business, pull your current rate now. You have until October 30 to fix carrier selection and cut-off times. After that, your B2B offers are exposed.

6. Liability insurance through Amazon Insurance Accelerator

Effective November 2, 2026. Sellers based in mainland China must purchase commercial liability insurance through the Amazon Insurance Accelerator (AIA) programme. Using your own insurer is no longer permitted even if the policy meets Amazon's requirements.

Amazon has not voided existing policies, but renewals will likely need to route through AIA.

What to do: if this applies to you, start the AIA process in October. If you source from China but your selling entity is elsewhere, this does not apply — check which entity holds the account rather than where your supply chain sits.

What these six have in common

Three of the six (peak fees, inbound cutoffs, dangerous goods) can hit you during BFCM week, when the cost of a mistake is highest and your attention is lowest. Two carry outright suspension risk.

The pattern across all of them is that enforcement dates were chosen to land before peak, which means Amazon expects compliance to be finished, not in progress, by the time traffic arrives.

Your October checklist

1. Rebuild unit economics and break-even ACoS with peak fees.
2. Verify BFCM inventory is received, not just shipped, before October 28.
3. Upload missing Safety Data Sheets; freeze listing edits in dangerous-goods categories.
4. Audit every bundle ASIN against the new packaging rule.
5. If FBM and selling B2B, check your business-hours delivery rate against the 90% threshold before October 30.
6. China-based sellers: begin AIA enrolment ahead of November 2.
