An Amazon FBA reimbursement rejected on first review is rarely the end of the claim. Amazon declines claims that fall outside the window, sit under the wrong claim type, duplicate an earlier claim or lack the records it asks for. Each of those reasons points to a specific fix, and some of them cannot be fixed at all. The work after a rejection is diagnosis first. Read the decision, match it to the reason, check whether the window is still open, and only then decide whether a rebuilt dispute is worth filing. For customer return reimbursements, Amazon accepts valuation disputes within 60 days after the reimbursement is issued. For losses before a customer order, valuation is disputed through the Get help and resources page or Seller Assistant, with proof of your sourcing cost. Amazon caps any single unit at $5,000 in the US and £2,000 in the UK, so a high-value item can lose money even on a winning claim.

Why an Amazon FBA Reimbursement Claim Gets Rejected

The FBA inventory reimbursement policy promises that if an item you send to Amazon is lost or damaged at a facility or by a carrier operated by or for Amazon, Amazon replaces it or reimburses you. That promise has conditions, and a rejected claim almost always failed one of them. Amazon pays on its own records first. Your claim succeeds only where your evidence shows the units reached Amazon’s custody and that Amazon’s record of what happened to them is incomplete or wrong. Most rejected claims we review fail on missing proof of receipt.

The seven reasons we see most

1. Filed outside the window. Every claim type has a start date and an end date. A late claim is ineligible, and Amazon says so on each claim page. A premature claim, such as a customer return claim before day 60, is also declined.
2. Filed under the wrong process. A unit lost inside the warehouse is a fulfillment center operations claim. A unit that never arrived is a shipment to Amazon claim. The facts may be right and still be rejected because they were sent through the wrong door.
3. Shipping plan mismatch. The policy requires that you sent the exact items and quantities stated in your shipping plan. If the box contents differed from the plan, the shipment claim fails at the first condition.
4. Missing proof of delivery or ownership. Shipment claims need proof of delivery and proof of inventory ownership showing purchase date, matching product names and quantity. Without both, Amazon has nothing to weigh against its receiving record.
5. Already reimbursed or already claimed. Amazon pays many cases automatically. A claim for a unit already paid, or a second claim on the same shipment, is declined. Amazon allows one claim per shipment.
6. Outside the policy. Defective items, customer-damaged items, recalled items, units disposed of at your request, units removed because of a policy violation and refunds you issued directly are all excluded.
7. Account not in normal status. The eligibility list requires the selling account to be in normal status when you file and while the claim is under review, including during any appeal. A claim filed while the account is deactivated or under review can fail on that condition alone, however strong the evidence.

Rejected compared with partly paid

Sellers often describe a low payment as a rejection. They are different problems with different fixes. A rejection means Amazon found the claim ineligible or unsupported. A partial payment means Amazon accepted liability and paid a value you disagree with. On the US policy, losses before a customer order are paid at your sourcing cost, or at Amazon’s estimate if you never entered one, and losses on customer returns are paid at the refund or replacement amount minus applicable fees. The US cap is $5,000 per unit, and the UK cap is £2,000. If your complaint is the amount, the fix is a valuation dispute with proof of cost. If your complaint is the decision, the fix is a rebuilt claim with the missing evidence.

Why repeat filing makes things worse

The policy names insufficiently researched or premature requests, and large numbers of requests in a short time, as activity that interferes with Amazon’s capacity to help other sellers. Sellers who repeat it may see delayed support on their cases, monitoring, investigation and account action. Refiling the same rejected claim with the same documents is exactly this behavior. A rejection is a reason to stop and diagnose, and it is never a reason to send the claim again unchanged.

The 60-Day Dispute Window

The 60-day figure sellers hear about comes from a specific line of the policy. In the section on post-order losses, Amazon states that if you do not agree with its valuation of a unit, you can file a claim on the Get help and resources page in Seller Central, or through Seller Assistant, within 60 days after the reimbursement is issued. The UK page uses the same wording and the same 60 days. That window applies to valuation of customer return reimbursements. It does not reopen a claim that was rejected because the original filing window had closed.

Pre-order losses work differently. Shipment, warehouse and removal losses are valued at sourcing cost. You submit or correct that cost on the Manage Your Sourcing Cost page, and Amazon states you can dispute a reimbursement claim through the Get help and resources page or Seller Assistant. If Amazon declines your submitted cost, it pays on a previously approved amount or on its own estimate. Amazon may decline a sourcing cost submission if it is an outlier against similar products, or if the documentation is forged, tampered with or illegible. It may also decline if the account is suspected of fraud or significant policy violations. The same applies if you received a decision on a cost update or valuation dispute for the same item within the last 30 days and supplied no new information.

Read together, those rules give a seller three clocks to track after a rejection or short payment.

• The original claim window. If it is still open, a corrected claim may be possible. If it has closed, the unit is lost to the process.
• The 60-day valuation window for customer return reimbursements, counted from the day the reimbursement was issued.
• The 30-day reconsideration rule for sourcing cost and valuation disputes. A second request inside 30 days needs new information or it will be declined on that ground.

We read each window above on Amazon’s US claim pages on November 3, 2026. The shipment window is the longest at nine months, and the fulfillment center window is 60 days from the day the unit shows as lost or damaged in the Inventory Defect and Reimbursement portal or the Inventory Ledger report. Amazon edits these pages without notice, so confirm the window for your store on the day you file. The parent guide on how to win a denied Amazon FBA reimbursement claim walks through each claim type from the start.

Proof of Inventory and Value

Every reimbursement dispute has to prove two things. The units existed and reached Amazon, and they were worth the amount you claim. Amazon’s records already contain its version of both. Your evidence has to show where its version is incomplete.

Proof the units reached Amazon

For shipment claims, the shipment to Amazon claim page asks for proof of delivery. For less-than-truckload or full-truckload freight, that means a delivery document showing the number of boxes and the total weight when the carrier picked up the shipment, stamped by Amazon to confirm it was received and signed for at the fulfillment center. Amazon notes your carrier should have a copy. For small-parcel shipments, Amazon needs the active tracking ID for each package, confirmable by the carrier. If you did not use an Amazon partnered carrier and did not enter tracking when you created the shipment, you must enter it before you can be reimbursed.

This is the evidence that most often decides a shipment case. A freight document without an Amazon stamp, or tracking for some boxes and not others, leaves the receiving record unchallenged. When we rebuild these cases, the first task is getting the signed and stamped delivery document from the carrier, because nothing else carries the same weight.

Proof you owned the units

Amazon accepts a supplier invoice, a receipt from another seller, or a signed packing slip if you are the manufacturer. The document must include the date of purchase, product names matching the lost or damaged items and the quantity. A document showing fewer units than you are claiming caps your claim at the documented number. Keep the original file. Amazon lists forged, tampered or illegible documentation as grounds to decline a sourcing cost submission, and an edited document turns a money question into an integrity question.

Proof of value

Value disputes rest on your sourcing cost, which is your cost to buy the product from a manufacturer, wholesaler or reseller, or to produce it if you manufacture it. The definition excludes shipping, handling, customs duties and similar costs, so leave those out of the figure. When no cost was on file, Amazon used its estimate, built from comparable products sold by Amazon, other sellers and wholesale channels. A specialist or premium item can be undervalued by that method. Units that were already unsellable when lost or removed are paid at a reduced estimated cost, and Amazon may ask for more documents to set that value. The answer for sellable stock is to enter your cost on the Manage Your Sourcing Cost page with the invoice that supports it, then dispute the affected reimbursements with the same evidence.

For customer returns, value is the refund or replacement amount minus fees. A reimbursement is not final either. If a reimbursed unit is later found and returned to your inventory, or the payment was made in error, Amazon reserves the right to reverse the credit, and reimbursed units can be sold through Amazon Warehouse or other channels. Arguing your production cost does not change that formula. A valuation dispute on a return should show that the calculation was applied to the wrong order amount or the wrong fees.

The business models that struggle with proof

• High-volume FBA sellers ship so often that small receiving shortfalls never get traced back to their delivery documents. Assign each inbound shipment an owner who files the stamped proof of delivery the day it arrives.
• Sellers who rely on automatic reimbursement rarely keep claim-ready files, because they expect never to need them. Keep the invoice, the delivery proof and the shipment ID together for every shipment anyway.
• Sellers of high-cost or seasonal items lose the most to estimates. Enter verified sourcing costs at launch so a later loss is valued on your number.
• Sellers using reimbursement services that file in bulk may not know what evidence went in under their name. Ask for every filing and its attachments, and withdraw what you cannot support.

Shipment and Removal Discrepancies

Two kinds of discrepancy produce the most disputed rejections, units Amazon says it never received, and removal orders that arrived short or damaged. Both depend on reconciling your records with Amazon’s before you argue anything.

Inbound shortfalls

Amazon’s shipment claim page tells you what to check first. Confirm the shipment’s contents and unit counts match the shipping plan you created. Check the Contents tab for any discrepancy between your plan and what the fulfillment center received, using Amazon’s reconcile shipment guidance. Check the Reimbursements report to see if you were already reimbursed. Only then file, with the shipment ID, ownership proof and proof of delivery. Once Amazon completes its investigation it confirms whether the claim is eligible for replacement or reimbursement, and in some cases Amazon reconciles the shipment instead.

Because Amazon allows one claim per shipment, a shipment claim rejected for missing proof is often closed for good. That makes the first filing the one that matters. If you have not yet filed on a shipment, do not file until the stamped delivery document or full tracking is in hand. Amazon also notes that sellers who generate a high number of shipping problems affecting receiving operations may face investigation and monitoring, which can affect Prime eligibility or delay future reimbursements. Clean prep and accurate box contents protect your claims as much as they protect receiving.

Removal shortfalls and damage

The removals claim page covers units lost or damaged by Amazon or its carrier after leaving an Amazon facility on the way to your return address. Units removed because you violated a program policy are excluded. The windows are tight. For units lost in transit, file no sooner than 15 days from the last confirmed movement and no later than 75 days from the date the shipment was created, and for damage or grading disputes, file within 60 days of delivery.

The evidence is heavily photographic. For missing units or components, Amazon lists the removal order ID, FNSKU, shipment ID, quantity and a description of the issue. It also asks for full images of the unit, images of the tracking labels or packing slips from the packages, and images of any box damage and the LPN barcode sticker. When the LPN or FNSKU label is not available, add six-sided product images. A short removal shipment needs more again. Amazon asks for an image of the entire shipping label showing the tracking ID and weight, a copy of the proof of delivery that calls out the short receipt, and the packing list with the missing unit marked. Open every removal carton on camera and photograph labels, packing slips and box faces before you cut the tape. A claim rebuilt weeks later without those images has little to stand on.

Warehouse losses and returns

For warehouse losses, use the Inventory Defect and Reimbursement portal described on the fulfillment center operations claim page. Its Resolved tab shows each defect Amazon has resolved, with the reason and amount. Amazon states that if you disagree with a resolution on that tab, you can file a claim using the information there, inside 60 days of the loss being reported. For customer returns, the customer return claim page sets the window at no sooner than 60 days and no later than 120 days after the refund. Grading follows the item’s physical condition at the fulfillment center and the buyer’s chosen reason does not decide it, and that Amazon will not waive or modify a damage fee at a seller’s request. Disputes that argue the return reason, or ask Amazon to reverse a damage fee, are disputes the policy has already answered.

Rebuilding the Dispute

Our method rests on one position, that the records establish Amazon’s liability, and the reimbursement is due in the amount those records support. A rebuilt dispute has to add something the first one lacked. If you cannot name what is new, you are not ready to file again.

Step by step

1. Read the decision and name the reason. Match Amazon’s response to one of the seven rejection reasons above. Write the reason down in one sentence before doing anything else.
2. Check every clock. Confirm whether the original claim window, the 60-day valuation window or the 30-day reconsideration rule still allows a filing. If none does, stop, log the loss and fix the gap in your monthly reconciliation.
3. Withdraw what you cannot support. Remove duplicate units, units already paid and any line without evidence. A narrower claim with complete proof reads as credible. A broad claim with gaps reads as bulk filing.
4. Reconcile the numbers again. Units shipped, units received, adjustments, removals and reimbursements for each FNSKU. The difference you can prove is the claim.
5. Obtain the missing evidence. The stamped delivery document, full parcel tracking, the supplier invoice with matching product names, or the photographs and LPN for a removal.
6. Name the root cause. State the shipment, FNSKU and event, such as units received short with proof of full delivery, units damaged in the warehouse, a return refunded and never received, or a removal that never arrived.
7. Show the calculation and make one ask. Units, unit value and its source, and total. Request reimbursement of that amount for those units.
8. File once through the right channel and log it. Use the claim tool on the claim page, the Get help and resources page or Seller Assistant, as the policy directs for that claim type. Record the case ID, date and the date any further window closes.

What the rebuilt dispute says

Keep the message short and factual. Open with the case ID and the units at issue. State the root cause in one or two sentences. List the evidence attached and what each item proves. Show the calculation. Close with the single request. Do not argue tone, describe hardship or blame the carrier, the warehouse or Amazon’s systems. Those statements do not change the record, and they signal that the seller is arguing instead of documenting.

First rejection compared with a rejection pattern

A single rejected claim carries no penalty. It is the normal outcome when records are thin. A pattern is different. If several claims have been rejected as duplicates or premature, or if an outside service filed in volume under your account, stop filing and audit everything in flight first. If Amazon has already taken account action under the reimbursement policy, that action needs its own appeal built on the same method our guide to writing an Amazon Plan of Action describes, covering the specific cause, the claims withdrawn, the reconciliation completed and the filing controls now in place. If funds are held while that is resolved, our guides on funds held on a deactivated account and the DD+7 account-level reserve explain the payout side.

Regional rules and the law

The reimbursement policy runs on the US store through sellercentral.amazon.com and on the UK and EU stores through Seller Central Europe. The structure matches, while caps and some routing differ. The UK page caps a unit at £2,000 against $5,000 in the US. Treat what follows as a map of the routes that exist, and take advice from a licensed lawyer in your jurisdiction before you rely on any of them.

• United States. The relationship is set by the Amazon Services Business Solutions Agreement and general contract principles, including the implied duty of good faith and fair dealing. Section 20 of the agreement sends disputes to binding arbitration, with an exception for small claims court. For US sellers the governing law is the law of the State of Washington together with the Federal Arbitration Act, and the governing courts sit in King County, Washington. Where value owed under the policy is withheld without basis, some sellers frame it as conversion. We keep that out of a first or second dispute and rely on the record.
• European Union. The Platform-to-Business Regulation, Regulation (EU) 2019/1150, requires a free internal complaint system covering measures or behavior of the platform that relate directly to its services and affect the business user (Article 11), and requires platforms to name two or more mediators in their terms (Article 12). The regulation has applied since 12 July 2020, and the complaint system must be free of charge for business users.
• United Kingdom. The UK keeps its own version of Regulation (EU) 2019/1150, published on legislation.gov.uk with Article 11 still listed as current law, so UK business users have the same internal complaint route.

The Digital Services Act, which has applied in full since 17 February 2024, gives a complaint route under Article 20 for at least six months after a decision. That route and the out-of-court route are built for decisions taken because information is illegal or breaches terms, such as removals and account suspensions. A reimbursement amount is a payment dispute, so in the EU and UK the P2B complaint route is the closer fit after Amazon’s own claim process is exhausted.

Frequently Asked Questions

How long do I have to dispute an Amazon reimbursement?

Within 60 days after the reimbursement is issued, for valuation disputes on customer return reimbursements filed on the Get help and resources page or through Seller Assistant. Pre-order losses are disputed through Get help with sourcing cost evidence, and Amazon declines a repeat request on the same item within 30 days unless you add new information.

Why was my FBA claim rejected?

Usually because proof of inventory, value or the discrepancy was missing, or because the claim was filed outside its window or under the wrong claim type. Duplicate claims, units already reimbursed and shipping plan mismatches are the other common causes. Match the decision to one reason before you file again.

What does Amazon reimburse?

Lost, damaged or misplaced FBA inventory and customer returns that were refunded but not returned, when the case meets the policy’s conditions. Pre-order losses are paid at sourcing cost or Amazon’s estimate, and customer return losses at the refund or replacement amount minus fees, up to $5,000 per unit in the US.

Does Amazon reimburse automatically?

Many cases are reimbursed automatically, and you should check the Reimbursements report before filing anything. Cases the automation misses must be claimed by you inside the window for that claim type. Claiming a unit Amazon already paid is declined and counts against your filing history.

What evidence helps?

Invoices, shipment records and proof of delivery. Specifically, an Amazon-stamped freight delivery document or full parcel tracking, a supplier invoice with the purchase date, matching product names and quantity, and the identifiers from Amazon’s own reports, such as the shipment ID, FNSKU or order ID.

Get Help With an Amazon FBA Reimbursement Dispute

A single rejected claim can usually be diagnosed with the method above. We help most when the discrepancy spans dozens of shipments, when an outside service filed claims you now need to unwind, or when the account has been actioned for claim volume. Those cases need the reconciliation and the appeal rebuilt together, claim by claim.
