Amazon extended the FBM refund processing window to four calendar days

What changed

Amazon announced that the seller-fulfilled refund process would move from two business days to four calendar days before automated refunds trigger. The same notice also clarified that once Amazon issues the automatic refund, sellers generally lose SAFE-T reimbursement eligibility except in specific situations such as items lost in transit or delivery confirmation errors outside the seller’s control.

Who it impacts

US seller-fulfilled merchants, agencies managing return operations, and anyone with internal SOPs built around the older two-day refund timeline.

Why it matters

This is not just a policy wording change. It changes the operational timer for return assessment, restocking-fee decisions, and escalation. Teams that see only the extra time and miss the SAFE-T trade-off may actually lose recovery options.

What to do now

1. 1. Update internal return SOPs from the old two-business-day language to the new four-calendar-day workflow.
2. 2. Train operators to distinguish between extra assessment time and reduced reimbursement options after an automated refund.
3. 3. Review whether your team should use Guided Refund workflow more consistently for condition-based evidence capture.
