FBA reimbursement claim deadlines: the calculator
A refund that never came back, a unit lost in a warehouse, a return the carrier broke — each can be claimed, but only inside a window. File a day early and it is rejected; a day late and the money is gone. Enter the date and see where you stand.
Pick what happened and enter the date to see the window.
Check several dates at once
Slashed dates like 03/07/2026 are read as . ISO dates (2026-07-03) and written months are always unambiguous.
Nothing leaves your browser. The dates and figures you type are worked out on this page and are not sent or stored anywhere.
Amazon decides every claim; this shows what the published rules entitle you to ask for. Rules checked 26 September 2026 — check Seller Central for your marketplace before relying on a date.
The three claims, and their windows
Refunded, item never returned
The customer was refunded (or sent a replacement) and the item never arrived back at Amazon. The claim opens on day 60 — the customer’s return period is still running before then, and an early claim is rejected — and closes on day 120. It is valued at the refund.
Amazon has reimbursed many of these automatically since 1 November 2024. Check your reimbursements report first: a unit already reimbursed must not be claimed again. File the rest through Seller Central’s case log, with the order ID and the refund date.
Returned, damaged by the carrier
The item did come back, but the returns report grades it as damaged by the carrier rather than by the customer. Amazon’s published rules are less explicit about this case than the other two, so the calculator applies the customer-return window (day 60 to day 120 after the refund, valued at the refund) as a working assumption — check the case type Seller Central offers before relying on the dates. Carrier damage on returns is especially common on breakables, where the box did not protect the product.
Lost or damaged in a fulfilment centre
A unit your inventory ledger shows as lost or damaged in Amazon’s building. The claim must be filed within 60 days of the date it was reported. Since 31 March 2025 it is valued at manufacturing cost, not the selling price. Amazon has reimbursed many of these automatically since 1 November 2024; where it has not, file with the ledger reference and your supplier invoice as evidence of cost.
Manufacturing cost: set it, or Amazon guesses
Units lost or damaged before a customer order are reimbursed at manufacturing cost — your cost to source the product from the manufacturer or supplier. If you have not set it in Seller Central (Manage Your Manufacturing Cost), Amazon estimates it, and an estimate below your invoice under-pays every future claim. Setting it from the supplier invoice is a one-off job that pays on every loss after it.
Freight, duty and handling are excluded, so they are never reimbursed. On a unit imported from China with a 25% Section 232 or Section 301 line, that can be a large share of what the unit really cost you — lost whatever you claim. It belongs in your landed cost, and in how hard you press the warehouse. Our landed cost calculator shows the gap.
Why claims get missed
Amazon’s own automation now pays most of these unprompted — which is exactly why the rest slip. The ones it misses look like every other line in four different reports, the windows are short, and a refund that is too early to claim today is too late to claim a few weeks after you next look.
Supercargo’s Recoveries ledger does this across every listing: it reads the returns, reimbursements, refunds and inventory ledger, matches out what Amazon has already paid, and lists every claim with its window and value, closing-soonest first. In the demo those recoveries come to more than a year of the subscription. See the recoveries ledger · what the hours would cost by hand
Questions
When can I file a claim for a refund where the item was never returned?
From day 60 to day 120 after the customer was refunded (or sent a replacement). Amazon does not accept the claim before day 60, because the customer’s return period is still running, and after day 120 it has expired. It is valued at the refund. Amazon has reimbursed many of these automatically since 1 November 2024, but not all of them — check your reimbursements report before filing so you never claim twice.
How long do I have to claim for inventory lost or damaged in a fulfilment centre?
60 days from the date the unit was reported lost or damaged. Since 31 March 2025 these units are reimbursed at manufacturing cost — what the product cost you from your supplier — not the selling price.
What is “manufacturing cost”, and what if I have not set it?
It is your cost to source the product from the manufacturer or supplier; freight, duty and handling are excluded. You can set it yourself in Seller Central (Manage Your Manufacturing Cost); if you have not, Amazon estimates it. Setting it from your supplier invoice means every future warehouse reimbursement is paid on the right figure.
Why are freight and duty never reimbursed?
Because reimbursement for units lost before an order is valued at manufacturing cost, which excludes shipping, handling and customs duty. The difference between your landed cost and your supplier cost is lost on every such unit, whatever you claim — worth knowing when you decide how hard to chase the warehouse, and a reason to keep landed cost accurate in the first place.
Do the windows differ by marketplace?
The windows here are the published US rules as checked on 26 September 2026. Amazon changes these rules, and marketplaces can differ, so check the reimbursement policy in Seller Central for the marketplace you sell in before relying on a date.
Is anything I type sent anywhere?
No. The dates and figures are calculated on the page and are not sent or stored. Close the tab and they are gone.
