FBA Returns: How to Set Custom Grading Rules for Resale

Every FBA return is inspected by Amazon and given a disposition: back to sellable stock, sold as used, or marked unfulfillable. For years sellers had little say in that decision, and many found good units written off or damaged units put back on the shelf. Customized grading lets you tell Amazon what "sellable as new" means for your products. This guide explains how it works and how to write rules that recover more value without risking customer complaints.

How Amazon grades FBA returns

When a customer returns an FBA order, the fulfillment center inspects the item and assigns a condition. Broadly, an item can go back into your sellable inventory as new, be resold as used through programs such as FBA Grade and Resell, or be classed as unfulfillable, in which case you choose removal, disposal or liquidation.

Until recently that inspection followed Amazon's general standard for every product. A general standard cannot know that your supplement is unsellable once the inner seal is broken, or that your phone case is perfectly resellable if the outer sleeve is slightly creased. That gap is where most returns value was lost.

What customized grading changes

Customized grading, announced in Seller Central in October 2026, lets you submit your own criteria for how your FBA returns are evaluated. Amazon uses your input as guidance during grading, alongside its standard process. According to Amazon, you can:

  • Submit criteria by category, including seal and packaging, included accessories, product authenticity indicators, device capabilities and other requirements.
  • Apply rules to specific ASINs, to your whole catalog, or through a CSV upload.
  • Set instructions for when items can be restored to new and when they should be sold as used, including used price percentages by condition.

ASINs that are not covered by one of your rules continue to use Amazon's default grading. Your rules also work with Grade and Resell, so units that fail the "new" standard can still be sold as used at a price you have set.

Which products benefit most

Products with clear seal rules

Beauty, personal care, supplements, food and anything consumed or applied to the body should usually be graded strictly. A broken seal should mean the unit is not sold as new. A clear rule protects you from negative reviews and safety complaints when a used unit reaches a new customer.

Products that survive returns well

Hard goods such as kitchen tools, phone accessories, home décor and sporting goods are often returned unused, in packaging that is only slightly worn. Here a rule that accepts minor outer packaging wear as sellable can bring many units back into stock instead of into the unfulfillable pile.

Products with accessories

Electronics, toys and kits are frequently returned missing a cable, manual or small part. A rule that lists the required components tells graders exactly what makes the unit complete, and what condition it should be sold in if something is missing.

Devices that can be tested

For powered products, device capability criteria let you state what must work, for example that the unit powers on and charges, before it can be considered resellable.

How to set up your first rules

  1. Pull your returns data. Download the FBA customer returns report for the last 6 to 12 months. Note return volume, return reasons and current dispositions by ASIN.
  2. Find the leaks. Look for ASINs with a high share of units marked unfulfillable or customer damaged where the reason given suggests the product was unused, for example "no longer needed" or "bought by mistake".
  3. Write criteria by category. For each product group, write short, testable rules: what packaging condition is acceptable, which seals must be intact, which parts must be present, and what must function.
  4. Set used pricing. Decide what percentage of the new price each used condition should sell at. Be realistic: an overpriced used unit sits in storage and costs you fees.
  5. Apply rules in Seller Central. Go to the Customized grading settings and assign rules to ASINs individually, to the full catalog, or by CSV for larger catalogs.
  6. Review after 60 to 90 days. Compare the share of returns restored to sellable stock before and after, and check reviews for any mention of used or damaged items.

Write rules that graders can apply

Graders handle large volumes. Rules work best when they are specific and visual rather than subjective.

  • Good: "Sellable as new if the inner foil seal is intact and the outer box has no tears longer than 1 cm."
  • Weak: "Sellable as new if it looks good."
  • Good: "Must include charger, USB-C cable and quick start card. If the cable is missing, sell as used, Good condition."

Keep the strictest rules on anything that touches health, safety or food. A few extra units recovered are not worth an account health complaint or a safety report.

How this fits a wider returns strategy

Grading rules recover value after a return happens. The bigger saving is fewer returns in the first place. Read the return reasons alongside your listing: if customers keep returning a product as "not as described" or "wrong size", the fix is usually in the images, size chart or bullet points. Our guide to listing optimization covers this, and our inventory recovery service handles reimbursement claims for units lost or damaged in Amazon's care.

Also keep in mind that Amazon extends its return window over the November and December holiday period, so return volume usually rises in January. Setting your grading rules before then puts them in place for the busiest returns month of the year.

What this means for sellers

Customized grading gives brand owners a direct say in a process that used to be a black box. Start with your highest return ASINs, write clear and testable rules, set sensible used pricing, and review the results after a couple of months. Sellers with large returns volume can recover a meaningful amount of inventory each year, while keeping strict standards where customer safety is involved.
