Amazon FBA Inventory Reimbursement: 2026 Policy & Claims

TL;DR

Amazon FBA inventory reimbursement is the payment or replacement Amazon provides when eligible FBA inventory is lost or damaged under Amazon’s control. Since March 2025, pre-order losses are valued at manufacturing cost (not retail price), while post-order losses still follow sales-price logic. Claim windows have shortened significantly, so monthly reconciliation is no longer optional. Sellers who skip audits or accept Amazon’s default cost estimates risk leaving real money on the table.

Every Amazon seller using Fulfillment by Amazon will eventually lose inventory. Units go missing during inbound shipping, get damaged inside fulfillment centers, vanish during removal shipments, or never come back after customer returns. Amazon acknowledges this. The question is not whether it happens. The question is whether you get paid fairly when it does.

That is what Amazon FBA inventory reimbursement is about. And since the rules changed in 2025, most sellers need to rethink how they approach it.

If your Amazon operations already feel stretched thin, EZCommerce’s Amazon services cover FBA fee audits, compliance case management, and reimbursement support as part of a broader account management program.

What Is Amazon FBA Inventory Reimbursement?

Amazon FBA inventory reimbursement is the replacement or payment Amazon provides when eligible inventory sent through Fulfillment by Amazon is lost or damaged at an Amazon facility or by a carrier operated by or on behalf of Amazon. Amazon may replace the item with a new unit of the same FNSKU or reimburse the seller financially.

In practical terms: if Amazon loses or damages your FBA inventory while it is under Amazon’s responsibility, Amazon may owe you either a replacement unit or money. But the amount, and whether you qualify at all, depends on where the loss happened, whether a customer order existed, whether the unit was sellable, whether your account and shipment were compliant, and whether you can prove the correct value.

This is not free money. It is a policy-driven process with eligibility rules, valuation formulas, documentation requirements, and deadlines.

Why FBA Reimbursement Matters More After the 2025 Policy Change

Two changes reshaped how Amazon handles FBA inventory reimbursements.

Change 1: Proactive reimbursements. Starting November 1, 2024, Amazon began proactively reimbursing sellers for FBA items lost in fulfillment centers as soon as the loss is reported. Amazon said “almost all” warehouse lost/damaged and customer return cases would be handled automatically. Removal claims, however, still require manual filing.

Change 2: Manufacturing-cost valuation. Effective March 10, 2025, Amazon shifted how it values pre-order lost or damaged inventory. Instead of basing reimbursement on the item’s sale price, Amazon now uses manufacturing cost for items lost or damaged before a customer order.

The combination of these changes creates a paradox. Amazon handles more reimbursements automatically, which sounds good. But the automatic amounts are often lower than what sellers expect, because pre-order losses are now tied to manufacturing cost rather than retail value.

Practitioners on Reddit report exactly this frustration. One seller described a product costing $68 (before additional shipping and customs) that was reimbursed at just $21 per unit. That gap between real cash exposure and reimbursement value is what makes FBA inventory reimbursement a margin issue, not just an operations task.

Lost inventory also disrupts your inventory forecasting and restock planning, creating downstream effects on BSR and advertising momentum that reimbursement dollars alone cannot fix.

Types of FBA Inventory Reimbursement Claims

Amazon’s reimbursement policy groups claims into four categories. Each has different evidence requirements, timing rules, and valuation logic.

Claim Type	What Happened	Typical Seller Question
Shipment to Amazon	Units lost or damaged during inbound shipping or receiving	“Amazon received fewer units than I shipped. Can I claim?”
Fulfillment center operations	Units lost or damaged inside Amazon’s fulfillment network	“Inventory Ledger shows a loss. Was I paid?”
Customer return	Customer was refunded or replaced, but item was not returned or Amazon caused unsellable condition	“Did the return come back, and who damaged it?”
Removal	Inventory lost or damaged while Amazon ships it back to the seller	“I requested removal, but units are missing or arrived damaged.”

Understanding which category your loss falls into matters because it determines whether Amazon handles the claim automatically, whether you need to file manually, and how much you can expect.

When Is Inventory Eligible for Reimbursement?

Not every lost or damaged unit qualifies. Amazon’s FBA inventory reimbursement policy lists several eligibility conditions:

The item must be registered in FBA at the time of loss or damage.
It must comply with FBA product restrictions and inventory requirements.
The exact items and quantities must match what was stated in the shipping plan.
The shipment must not be canceled or deleted.
The item must not be pending disposal or disposed at the seller’s request.
The item must not be defective or customer-damaged.
The seller’s account must be in normal status during filing, review, and appeal.

That last point is worth emphasizing. Account health directly affects your ability to file and win claims. If your account has active warnings or policy violations, you may face delays or denials. Setting up automated account health alerts is a preventive step that pays off when you actually need to file a reimbursement.

The bottom line: eligibility starts before the claim. Shipment accuracy, labeling compliance, prep standards, and account health all play a role.

How Amazon Calculates FBA Inventory Reimbursement Value

This is where the 2025 policy change hits hardest. Amazon now uses two different valuation methods depending on when the loss occurred relative to a customer order.

Pre-Order Lost or Damaged Events

For items lost or damaged before a customer order (including shipment-to-Amazon, removals, and fulfillment center operations), Amazon reimburses at manufacturing cost. This applies to the majority of warehouse losses, inbound discrepancies, and removal shortages.

If the seller has not submitted a manufacturing cost, Amazon uses its own estimate based on comparable products sold by Amazon, other sellers, and wholesale channels.

Post-Order Lost or Damaged Events

When an item is lost or damaged after a customer has placed an order, Amazon still uses sales-price logic. It compares price indicators such as the seller’s median Amazon sales price over the past 18 months, other sellers’ median sales price, the current list price, and comparable product pricing. The reimbursement is generally tied to the estimated sale price minus referral and FBA fulfillment fees.

Maximum Reimbursement

Amazon caps reimbursement at $5,000 per eligible FBA unit and recommends third-party insurance for items valued above that amount.

Think of the pre-order/post-order split as the key framework. Pre-order events are treated as an inventory asset problem, valued at what the unit cost to acquire. Post-order events are treated as a sales transaction problem, valued at what the unit would have earned.

Manufacturing Cost Is Not the Same as Landed Cost

This distinction causes more confusion and frustration than any other part of the FBA reimbursement policy.

Manufacturing cost, as Amazon defines it, is the seller’s cost to source a product from a manufacturer, wholesaler, or reseller, or to produce the item if the seller is the manufacturer. It explicitly excludes shipping, handling, customs duties, and other costs.

Landed cost is the total amount a seller spends to get a unit ready for sale: product cost plus ocean freight, duties, customs fees, prep, labeling, inspection, and 3PL charges.

Here is a simple example:

Cost Component	Amount
Manufacturing cost (product sourcing)	$10.00
Ocean freight per unit	$2.00
Customs duties	$1.25
Prep and labeling	$0.75
Landed cost	$14.00
Amazon’s pre-order reimbursement basis	$10.00

A seller can be “correctly reimbursed” under Amazon’s policy and still be $4.00 short of their actual cash exposure per unit. For sellers importing products with high freight and duty costs, the gap can be much wider.

Practitioners on Reddit regularly flag this. In a 2025 thread, one seller listed packaging, labeling, international freight, customs, taxes, freight to Amazon FC, and personal time as costs that Amazon’s reimbursement ignores. Another handmade seller reported that Amazon’s estimated manufacturing cost was about half of their own calculated cost and that an update request was denied.

Understanding this gap matters for margin analysis. If you are tracking contribution margin, make sure your reimbursement recovery expectations reflect Amazon’s narrower manufacturing-cost definition, not your full landed cost.

How Amazon Estimates Your Manufacturing Cost (and How to Submit Your Own)

Sellers can provide their own manufacturing cost through the Manage Your Manufacturing Cost page in the Inventory Defect and Reimbursement (IDR) portal. If you do not submit a cost, Amazon will use its own estimate.

Amazon’s estimate is based on comparable products across Amazon Retail, other sellers, and wholesale channels. For common, low-cost products, the estimate is sometimes acceptable. For expensive, bulky, handmade, or niche products, it is often far too low.

Amazon may reject a seller’s submitted cost if:

The amount is an outlier compared with similar products or Amazon’s estimate.
Documentation is forged, tampered with, or illegible.
The account is suspected of fraud or significant policy violations.
The seller already received a decision for the same item within the last 30 days without new information.

Sellers on Reddit report mixed results with cost updates. One seller noted that about half of their updates were automatically approved, while others required invoices or were denied outright. The consensus in the community is clear: review your high-risk SKUs first. Expensive products, bulky items, handmade goods, high-duty categories, and seasonal inventory deserve priority attention.

Practical tip: Do not wait until you have a large loss to check Amazon’s cost estimate. Review it proactively for your top SKUs and submit corrections with clean documentation before a claim situation forces the issue.

Are FBA Inventory Reimbursements Automatic?

Partly. Since November 2024, Amazon proactively reimburses sellers for most fulfillment center losses and many customer return issues. But “automatic” does not mean “complete” or “accurate.”

Automatic reimbursement creates two separate questions:

Was a reimbursement issued at all? Amazon’s system may miss cases.
Was the reimbursement amount correct? Amazon may use its own cost estimate, which could be lower than the seller’s actual manufacturing cost.

Additionally, several claim categories are not automated:

Removal claims still require manual filing.
The IDR portal covers warehouse lost, warehouse damage, and customer returns, but Amazon has confirmed it does not include missing inbound, removals, or warehouse disposals.

The IDR portal is a dashboard, not a finance department. It gives you centralized visibility into certain defect types and reimbursement statuses, with filtering by date, SKU, ASIN, or defect type. But it is not a substitute for monthly reconciliation across all claim categories.

Current FBA Reimbursement Claim Windows

This is where many online guides get it wrong. Older articles still reference 18-month or 9-month filing windows. Those are outdated. Amazon announced updated claim windows effective October 15, 2025, and the new deadlines are significantly shorter.

Claim or Request Type	Current Window
Lost or damaged items	Within 60 days of reported loss or damage
Customer returns	45 to 105 days after refund or replacement
Removal orders lost	15 to 135 days from shipment creation
Removal orders damaged	120 days from shipment delivery date
Removal order grading	120 days from date item was removed from Amazon fulfillment network
Re-evaluation request	Within 90 days of initial claim

These windows mean a monthly audit is the bare minimum. For higher-volume accounts, running a check every two weeks is safer. If you miss the window, the claim opportunity is gone.

Seller Central Reports Used for FBA Reimbursement Audits

Knowing which reports to pull is half the battle. Amazon’s SP-API documentation defines the key data sources:

Inventory Ledger Report: An end-to-end reconciliation report showing inventory movements, including received inventory, customer orders, customer returns, adjustments, removals, damaged units, lost units, and found units.

FBA Reimbursements Report: Itemized details of seller inventory reimbursements, including reimbursement reason, updated daily.

Beyond these two, sellers should also monitor:

IDR portal (for warehouse lost, warehouse damage, and customer returns)
Manage FBA Shipments / shipment reconciliation (for inbound discrepancies)
Customer returns reports
Removal order detail and removal shipment detail

Every FBA reimbursement audit should reconcile three sources: the inventory event (what happened), the payment record (what Amazon paid), and the value record (what the unit was worth). If any leg of that triangle is missing or mismatched, you may have an unresolved claim.

For sellers managing inventory across Amazon and a Shopify store, reconciliation gets more complex. Cross-referencing FBA records against your D2C data is important, and our guide on integrating Shopify and Amazon inventory explains how to keep both channels in sync.

How to Check Whether Amazon Owes You an FBA Reimbursement

Here is a straightforward monthly workflow:

Export the Inventory Ledger for the last 30 to 60 days.
Filter for lost, damaged, removed, disposed, found, and return-related events.
Export the FBA Reimbursements Report for the same period.
Match inventory events to reimbursement IDs, case IDs, FNSKUs, ASINs, and dates.
Check whether Amazon used your submitted manufacturing cost or Amazon’s estimate.
Identify missing or low reimbursements.
Gather supporting documentation before filing.
File only well-researched claims with clear evidence.
Track case IDs, decisions, and any reversals.
Repeat monthly.

This process is not glamorous. It is accounting work. But it is the only reliable way to catch missed reimbursements and incorrect valuations before the claim window closes.

Request a free brand audit to find out if your account has unclaimed reimbursements, fee overcharges, or inventory planning gaps.

What Proof Helps With FBA Reimbursement Claims?

Amazon may ask for documentation to validate your claim or your submitted manufacturing cost. Keep these records organized by SKU:

Supplier invoices or manufacturer cost documentation
Purchase orders
Proof of payment (bank transfer, credit card statement)
Packing slips
Shipment ID
Tracking IDs (small parcel) or proof of delivery (LTL/FTL)
Box content photos
Removal order ID
LPN numbers where relevant
Product or package damage photos
SKU-level manufacturing cost worksheet

The pattern is clear: Amazon wants proof that you owned the inventory, shipped what you said you shipped, and that the unit cost what you claim it cost. Clean, SKU-level records make every claim faster and more likely to succeed.

EZCommerce demonstrated this kind of operational rigor in a case where a $1,200 Amazon Buy Shipping adjustment was reversed through proper documentation and dispute process.

Reimbursement Reversals

A reimbursement is not always final. Amazon’s policy states that if a reimbursement was made in error, or if a reimbursed item is later found and returned to inventory, Amazon reserves the right to reverse the reimbursement credit. Amazon may also dispose of reimbursed items, including by selling them through Amazon Warehouse or other channels.

This means your reconciliation process needs to track reversals, not only credits. A monthly audit that only looks for new reimbursements without checking for clawbacks will give you an incomplete picture.

Common Mistakes That Reduce or Delay FBA Reimbursements

Assuming automatic reimbursement caught everything. It does not cover all claim types, and the amounts may use Amazon’s estimates.
Waiting longer than the claim window. With 60-day windows on some categories, quarterly audits are too slow.
Confusing landed cost with manufacturing cost. Amazon’s policy defines manufacturing cost narrowly. Filing claims using landed cost figures will not match their system.
Not reviewing Amazon’s estimated manufacturing cost before a loss. The time to correct a bad estimate is before the loss, not after.
Filing premature or poorly researched claims. Amazon explicitly warns that sellers who repeatedly submit insufficiently researched requests may face delayed support, monitoring, investigation, or account action.
Submitting too many weak claims at once. Quality matters more than volume.
Ignoring reimbursement reversals. A credit that gets reversed is not income.
Forgetting removal claims are manual. The IDR portal and automatic systems do not cover them.
Treating the IDR portal as complete. It excludes missing inbound, removals, and disposals.
Not reconciling cost records by SKU and FNSKU. Without SKU-level cost data, you cannot identify underpayments.

Reimbursement is a margin issue, and margin protection is essential when you are trying to scale Amazon sales without losing profit.

Who Is Most Exposed to Reimbursement Shortfalls?

Not every seller faces the same risk. The gap between Amazon’s reimbursement and actual cash exposure tends to be largest for:

Handmade sellers whose labor and materials costs are hard to document in Amazon’s format
Private-label importers with high freight, duty, and prep costs
Bulky or heavy product sellers where shipping is a large percentage of unit cost
Seasonal sellers who lose inventory during peak periods, compounding the financial impact
High-SKU catalogs with weak cost documentation across hundreds of ASINs
Sellers relying heavily on FBA removals, which remain manual-claim only

Should Sellers Use an Amazon Reimbursement Service?

Reimbursement services can be useful, but they are not magic. Their value lies in disciplined reconciliation, documentation, and case follow-up, not in some secret access to Amazon’s systems.

Most professional reimbursement services charge 15% to 25% of recovered funds, according to commercial sources. Whether that fee is justified depends on your situation:

DIY may work if: You have a small catalog, low FBA volume, strong internal record-keeping, and the time to run monthly audits.

A service or agency may be worthwhile if: You have hundreds of SKUs, frequent FBA shipments, expensive products, high seasonal inventory, or no internal process for reconciliation.

Before hiring anyone, ask about account permissions they require, reporting transparency, claim methodology, appeal process, and how they handle compliance risk. Avoid vendors that guarantee recovery before auditing your account.

For brands with broader Amazon growth needs, reimbursements should be part of a larger operational system that includes inventory planning, fee audits, account health, compliance, and margin reporting. That is the approach EZCommerce takes through its Amazon management and EzGuard case management program.

A Note on Data Sensitivity

Amazon says seller-specific cost data submitted for reimbursement purposes is not shared with other sellers, including Amazon Retail, and is used only to calculate reimbursement and improve services.

Still, sellers worry. On LinkedIn, several practitioners have framed the manufacturing-cost submission process as a difficult trade-off: accept low estimates and leave money on the table, or hand over manufacturer invoices and COGS data to a company that is both your platform and a retail competitor.

The practical reality is straightforward. If you do not submit your manufacturing cost, Amazon uses its own estimate, which may be lower. If you do submit it, you gain control over the reimbursement valuation but share cost data with Amazon. Each seller needs to make that call based on their own business.

FAQ

What does FBA inventory reimbursement mean?

Amazon FBA inventory reimbursement is the replacement or payment Amazon provides when eligible FBA inventory is lost or damaged at an Amazon facility or by an Amazon-operated carrier. Amazon may replace the item with the same FNSKU or issue a financial credit.

Does Amazon reimburse the retail price for lost FBA inventory?

Not for pre-order losses. Since March 10, 2025, items lost or damaged before a customer order are reimbursed at manufacturing cost, which excludes shipping, duties, and handling. Post-order losses are still valued using sales-price logic minus applicable fees.

How long do sellers have to file an FBA reimbursement claim?

As of Amazon’s October 15, 2025 update, claim windows range from 60 days for lost or damaged items to 135 days for certain removal order claims. These are much shorter than the old 18-month windows that some older guides still reference.

What is manufacturing cost in Amazon’s reimbursement policy?

Amazon defines manufacturing cost as the cost to source a product from a manufacturer, wholesaler, or reseller, or to produce it if you are the manufacturer. It explicitly excludes shipping, handling, customs duties, and other costs. This is narrower than most sellers’ landed cost.

Are FBA reimbursements automatic now?

Many are. Amazon proactively reimburses most fulfillment center losses and customer return issues. But removal claims are still manual, and automatic reimbursements may use Amazon’s cost estimate rather than your submitted cost. Monthly reconciliation is still necessary.

Can Amazon reverse a reimbursement?

Yes. If the reimbursement was made in error or the item is later found and returned to inventory, Amazon can reverse the credit. Sellers should track reversals as part of their monthly audit, not just new credits.

What reports show lost or damaged FBA inventory?

The Inventory Ledger Report shows all inventory movements including losses, damages, returns, and adjustments. The FBA Reimbursements Report shows itemized reimbursement details and reasons. The IDR portal provides centralized visibility for warehouse lost, warehouse damage, and customer return defects, but excludes missing inbound, removals, and disposals.

What is the maximum FBA reimbursement per unit?

Amazon caps reimbursement at $5,000 per eligible FBA unit. For items valued above that amount, Amazon recommends third-party insurance.

FBA inventory reimbursement is not a one-time recovery project. It is a monthly finance-control process that touches inventory accuracy, cost documentation, claim timing, and margin protection. Sellers who treat it that way will consistently outperform those who only check when they notice something obviously wrong.
