What changes on October 31, 2026?

Amazon is moving some ASINs into different fee categories, effective October 31. Amazon is notifying affected sellers. Fees on those ASINs are then calculated with the new category.

Is a fee category the same as the category shoppers see?

No. Amazon says a product's fee category may not be the same as the category that appears to customers in the store. Each ASIN has one fee category, even if it shows in several places on Amazon.

Which fees depend on the fee category?

Referral fees vary by fee category. beBOLD Digital notes that Amazon may also use it for closing fees, FBA fulfillment fees and FBA returns processing fees.

Can I dispute a new fee category?

Yes. If you think an ASIN is in the wrong fee category, Amazon has a dispute process. Bring the ASIN, both categories, the product attributes and the part of Amazon's fee category guidelines that supports your case.

Amazon is moving some ASINs into different fee categories from October 31, 2026, and is notifying affected sellers, beBOLD Digital reported on October 13. The product page can stay exactly the same while the fee charged on every sale changes, so the check has to happen in the fee data, not on the listing.

The category you pay on is not the one shoppers see

Amazon's selling fees page says referral fees vary by product category, and that a product's fee category may not be the same as the category shown to customers. Each ASIN has one fee category, even if it appears in several places in the store. Amazon audits ASINs against its fee category guidelines, and this wave is the result.

The referral fee is the obvious change. beBOLD Digital notes that Amazon may also use the fee category for closing fees, FBA fulfillment fees and FBA returns processing fees. FBM sellers pay referral fees too, so merchant-fulfilled ASINs are in scope.

What to check for each affected ASIN

Amazon's Fee Preview report shows each ASIN's fee category and upcoming category changes. Start with the ASINs where the change costs the most in dollars, not the ones that sell the most units.

Current fee category and the category scheduled for October 31
Referral fee per unit today and under the new category
Margin per unit after the change
Advertising break-even, if the fee goes up
Q4 prices and promotions that no longer clear your margin

How a category move reaches your margin

Illustration only. The rates are hypothetical, not Amazon's schedule. Check your own categories on Amazon's fee pages.
Selling price	$30.00
Referral fee at a hypothetical 10% ($30 x 10%)	$3.00
Referral fee at a hypothetical 15% ($30 x 15%)	$4.50
Extra fee per unit ($4.50 - $3.00)	$1.50
Extra fees on 800 units in November ($1.50 x 800)	$1,200.00

In this example, a product earning $5.00 per unit before the change would earn $3.50 after it, 30% less, with no change to price or cost. For the full list of Amazon fees and how they stack, read Amazon seller fees explained.

Disputing a wrong category

If an ASIN lands in the wrong fee category, Amazon has a dispute process, explained in Understanding fee categories. Send the ASIN, the current and new categories, the product attributes, and the line of the fee category guidelines that supports your case. Filing before October 31 avoids weeks of charges at the wrong rate.
