Amazon extends FBM refund processing window to four calendar days from Jan 26, 2026
More time to inspect returned items, but missed deadlines may trigger auto refunds and limit SAFE-T reimbursement

Amazon has announced an important update to the seller fulfilled refund process that will come into effect from January 26, 2026. The announcement was made on Seller Central and is aimed at improving return management while giving sellers additional time to review returned items before refunds are automatically issued. The update is particularly relevant for sellers operating under the Fulfilled by Merchant or FBM model, where return inspection and refund decisions are handled directly by the seller.
What is changing in the refund timeline
Under the revised process, the refund processing window for seller fulfilled orders will be extended. Currently, sellers have two business days to process a refund after receiving a returned item. From January 26, 2026, this window will be extended to four calendar days. This change means that for most return delivery days, sellers will have more time to inspect returned products, check their condition, and take appropriate action before Amazon steps in with an automated refund.

When automated refunds will apply
If a seller does not issue a refund within four calendar days of receiving the returned item, Amazon may automatically process the refund on the seller’s behalf. Once an automated refund is triggered, sellers will generally not be eligible to file a SAFE-T claim for reimbursement. However, Amazon has clarified that exceptions will apply in certain situations. Sellers can still file a SAFE-T claim if the returned item was lost in transit, or if delivery confirmation was incorrect through no fault of the seller. In such cases, since the seller never received the item for inspection, reimbursement claims will remain valid.
Impact on SAFE-T claims
The update makes it more important for sellers to act within the revised four day window. Failure to do so could limit eligibility for Seller Assurance for e-Commerce Transactions, commonly known as SAFE-T, which protects sellers against unfair refunds. Amazon is clearly encouraging sellers to actively manage returns and document item condition properly to avoid losses.
Amazon recommends Guided Refund workflow
As part of the update, Amazon is strongly recommending the use of the Guided Refund workflow available on Seller Central. This workflow allows sellers to grade returned items, apply appropriate restocking fees, and upload supporting evidence if the item is returned in a condition different from how it was shipped. Using the Guided Refund workflow can help sellers make more accurate refund decisions and strengthen their position in case of disputes or claims.
Why this update matters for sellers
For FBM sellers, return handling often affects profitability. The extended processing window provides extra time to check for damage, missing parts, or misuse, reducing the risk of unnecessary refunds. It also encourages better documentation and structured return management, which can be crucial during claim reviews. Sellers who deal in high value, fragile, or condition sensitive products are likely to benefit the most from this change.
The update to the seller fulfilled refund process, announced on Seller Central, marks a meaningful shift in how Amazon balances customer experience with seller protection. By extending the refund processing window to four calendar days and promoting the Guided Refund workflow, Amazon is giving FBM sellers more control over return assessments. Sellers are advised to review their return handling practices ahead of January 26, 2026, to fully benefit from the new system and avoid automated refunds that could impact reimbursements.
