Amazon's $1m insurance rule and the 8 September deal cutoff

Amazon spent the week tightening the gates on Q4: a new $1 million liability insurance rule announced on 3 September, a deal submission deadline that closes tomorrow, and a peak fulfilment surcharge starting next month. eBay went the other way with a deliberately quiet September update, and Walmart spent three days in San Diego courting sellers. If you sell across several channels, this is a week of costs and deadlines rather than features.

Amazon's $1m insurance rule lands on 2 November

A Seller Central announcement dated 3 September changes who needs commercial liability insurance. Until now the trigger was $10,000 in sales in a month. From 2 November 2026, any seller with listings in categories that carry enhanced safety listing requirements needs a $1 million policy, regardless of turnover. Named examples include children's products, cosmetics and ingestibles, and anything with a lithium battery. It applies to existing listings, not just new ones.

That is a real cost for small and part-time sellers who have never needed cover before, and sellers based in Mainland China must buy through the Amazon Insurance Accelerator rather than their own broker. Eight weeks is enough time to get quotes, but not enough to leave it until half term.

Treat the premium as a channel cost, not an admin cost. If a $1m policy costs you a few hundred dollars a year and your toy or supplement range is doing thin margins, you need to know which ASINs are still worth carrying after insurance, fees and returns come off. That is exactly the kind of hidden drag /profitability is built to surface, and you can see it per channel once your /integrations/amazon account is connected.

The 8 September deal cutoff, then 32 cents a unit

Submissions for the autumn Prime Big Deal Days event close on 8 September. The window opened on 8 July and the $50 early-submission discount expired on 5 August, so there is no incentive left, only the deadline. Black Friday Week and Cyber Monday submissions close on 20 October, and the early-bird discount on those went on 5 September. Amazon still has not published consumer-facing October dates, and other outlets say the 2026 dates remain unconfirmed.

Miss tomorrow and your only remaining Q4 lever on Amazon is Black Friday. Worth checking which SKUs actually earned money on last year's deals before you submit again, rather than repeating the ones that shifted volume at a loss.

The maths has also moved. Amazon's holiday peak fulfilment surcharge runs from 15 October 2026 to 14 January 2027 at roughly $0.32 a unit, varying by size and weight band, and it stacks on the fuel and logistics fee added earlier this year. It is triggered by ship date, not order date, so late-shipping October orders get caught. Price your deals on the new numbers, and use /inventory to make sure you are not paying peak rates to ship stock you could have sent in earlier.

Quick hits

  • eBay: the September seller update landed with no significant policy or fee changes, mostly recycled content, plus bundle discounts now open to all sellers and a block on repeat unpaid-item buyers bidding across accounts - nothing to comply with, so switch bundle discounts on before peak.
  • Walmart: most items bought between 1 October and 31 December can be returned up to 31 January 2027, with exceptions including phones, major appliances, Dyson, food and select seasonal goods - plan cash flow around a four-month return tail.
  • Walmart: the Let's Grow! Marketplace Seller Summit ran 1-3 September in San Diego, covering roadmap changes, new tools and category expansions - the recaps tell you what the channel will push in 2027 before you commit budget.
  • Amazon: a 90% Business Hour Delivery Rate becomes mandatory on 30 September for seller-fulfilled Amazon Business orders to commercial addresses - if you fulfil your own B2B orders, fix weekday delivery windows now.
  • Multi-channel: Base Meet Up, Scale Up 26 published its agenda for 17 September at Kings Place, London, with B&Q Marketplace, Temu and Debenhams among the partners - a rare chance to meet UK marketplaces you might add next, and /integrations/b-and-q is ready when you do.
