Amazon Inbound Defect Fees 2026: What They Are and How to Avoid Them
Amazon now charges $0.32 to $5.72 per unit for shipments that arrive with problems. Here is how the inbound defect program works and how to stay compliant.
Amazon's inbound defect fee program launched in 2025 and changed significantly in 2026. Previously, shipments that arrived with prep or labeling problems were rejected or held. Now, Amazon assesses fees per defective unit, accepts the inventory, and deducts the fees from your account. For sellers with prep inconsistencies, these fees have become a significant unexpected cost.
What counts as an inbound defect
Amazon defines six defect categories for inbound shipments:
Unexpected items: products that arrive at a fulfillment center that were not on the shipment manifest. This happens when inventory gets cross-contaminated across shipments. Fee: $0.32 per unexpected unit.
Missing barcode: the FNSKU label is missing or unreadable. Fee: $0.16 per unit with a missing or unscannable barcode.
Prep issue: the item required prep (poly-bagging, bubble wrapping, etc.) but arrived without it. Fee: $0.32 per unit.
Damaged: the item arrives in condition that makes it unsellable. Fee: $2.45 to $5.72 per unit depending on damage severity.
Over-boxing: the item is over-packaged in a way that requires Amazon to remove and repack. Fee: $0.55 per unit.
Label issue: the FNSKU label is applied in the wrong location or is partially obscured. Fee: $0.16 per unit.
Why fees jumped in 2026
Before the prep service shutdown in January 2026, sellers who sent items without proper prep paid Amazon to fix it. The fee was $0.55 to $1.55 per unit. Now that Amazon no longer offers prep services, the inbound defect program is the enforcement mechanism. Units that arrive with prep problems are processed and the defect fee is charged, but Amazon will not fix the prep.
This means defective units may reach customers in non-compliant packaging. Amazon tracks this in the Inbound Problem Report and uses it to calculate your shipment defect rate, which affects your future inbound shipment permissions.
How to review your inbound defect charges
In Seller Central, go to Inventory > FBA Inventory > Shipments, then select a specific shipment and click on the Inbound Performance Report. This shows every defect flagged for that shipment, the fee charged, and the specific ASIN affected.
You can also access aggregate defect data under Reports > Fulfillment > Inbound Performance Report. Download the report and filter by defect type and date range to understand your defect patterns across multiple shipments.
Disputing incorrect defect fees
Amazon does make mistakes. A common error: a unit is flagged as "missing barcode" when the barcode was properly applied but faced inward during scanning. To dispute, file a case in Seller Support > FBA Issue > Inbound Shipment. Include photos from your prep process showing compliant labeling, and reference the shipment ID and the specific ASIN. Include the date of the defect charge from the inbound performance report.
Amazon reviews disputes within 7 to 14 business days. Keep photos from every shipment prep session for at least 90 days for this reason.
Preventing inbound defect fees
Implement a prep checklist for every shipment. For each ASIN, document: required prep type (bubble wrap, poly-bag, etc.), label placement location, box orientation for fragile items. Review this checklist with whoever handles prep before each shipment.
Run a pre-shipment audit. Before sealing boxes and applying shipping labels, check 5% to 10% of units for barcode scannability (a phone barcode scanner app works), correct prep application, and that no unexpected units have been mixed into the shipment.
Use a 3PL experienced with Amazon requirements. Third-party logistics providers that specialize in Amazon prep have systems that catch defects before shipment. Ask potential 3PLs for their defect rate per shipment before selecting one. The defect fees in one table
| Defect | Fee per unit | What triggers it |
|---|---|---|
| Unexpected item | 0.32 | A unit arrives that was not on the shipment manifest |
| Missing barcode | 0.16 | No FNSKU, or one that will not scan |
| Label issue | 0.16 | Label in the wrong place or partly covered |
| Prep issue | 0.32 | Required poly-bag, bubble wrap or suffocation label missing |
| Over-boxing | 0.55 | Packaging Amazon has to remove and repack |
| Damaged on arrival | 2.45 to 5.72 | Unsellable condition, rate depends on severity |
The fees look trivial per unit and are not trivial per shipment. A pallet of 600 units where one SKU went out without its poly-bag is 192 dollars in prep fees on a single mistake, and the same mistake repeats every time that SKU ships until somebody changes the checklist.
How the shipment defect rate is calculated
Amazon divides defective units by total units received across a rolling window, and shows the result in the Inbound Performance dashboard. That percentage, not the fee total, is what governs your access. A rising rate leads to restrictions on shipment quantities, mandatory appointment scheduling, and in the worst case a hold on creating new shipments to certain fulfilment centres.
Because it is a ratio, a small shipment with a couple of defects damages the rate far more than the same two defects inside a large one. If you are already on a warning, sending a small corrective shipment is the wrong move.
The reconciliation window
Defect charges and missing-unit claims share the same deadline: you have a limited window after the shipment is closed to open a case, and Amazon states 45 days for shipment reconciliation on most inbound issues. After that the case is refused on timing alone, whatever the evidence shows.
Build the check into the routine rather than the exception. When a shipment closes, pull the Inbound Performance Report for it that week, compare units sent against units received, and open one case covering every discrepancy at once rather than a case per ASIN.
A prep checklist by product type
| Product type | Required prep | The mistake that gets charged |
|---|---|---|
| Liquids in bottles or jars | Sealed in a bag, cap secured | Bag not sealed, counted as no prep |
| Powders and granular goods | Sealed bag | Original packaging assumed to be enough |
| Anything with an opening larger than 5 inches | Suffocation warning label | Label printed too small to read |
| Fragile or glass | Bubble wrap, drop tested | Wrapped but not taped, arrives loose |
| Sets sold as one unit | Sold-as-set label, single outer bag | Components labelled individually |
| Sharp items | Fully covered edges | Point exposed through the bag |
| Adult products | Opaque bag | Transparent bag used |
| Items with existing barcodes | Original barcode fully covered | FNSKU applied next to the old barcode |
That last row causes more missing-barcode charges than anything else. Two scannable barcodes on one unit is a scanning failure, not a labelling success.
A pre-shipment audit that takes twenty minutes
Before you tape the last box, pull five to ten percent of the units at random and check four things: the FNSKU scans with a phone scanner app, the label is on a flat surface and not wrapped round a corner, the required prep is present and sealed, and the SKU matches the manifest line. Log the check with a photo of the open box and the date.
Those photos are the reason to do it. A dispute without evidence from your own prep is a coin flip, and a dispute with a timestamped photo of the compliant unit is usually refunded. Keep them for at least 90 days.
Frequently Asked Questions
What is an Amazon inbound defect fee?
It is a per-unit charge Amazon applies when a unit arrives at a fulfilment centre with a labelling, prep, packaging or manifest problem. Rather than rejecting the shipment, Amazon receives the inventory, charges the fee, and records the defect against your inbound performance.
How do I see which units were charged a defect fee?
Open the Inbound Performance Report in Seller Central, either from the specific shipment under Inventory then Shipments, or in aggregate under Reports and Fulfilment. The report lists each flagged unit, the defect type, the ASIN and the fee applied, which is the detail you need for any dispute.
Can inbound defect fees be disputed?
Yes. Open a case under Seller Support with the shipment ID, the affected ASIN, the defect type and the charge date, and attach photographs from your prep process showing the unit was compliant. Amazon typically responds within 7 to 14 business days. Disputes filed after the reconciliation window closes are refused regardless of the evidence.
How do I avoid Amazon prep and labelling fees?
Write a per-ASIN prep specification covering prep type, label placement and packaging, follow it every shipment, and audit a sample of units before sealing the boxes. Most recurring charges trace to one SKU whose requirement nobody wrote down, not to general carelessness.
Does a high inbound defect rate affect my seller account?
It does not sit on the Account Health page alongside order defect rate, but it governs your inbound privileges. A persistently high rate leads to restrictions on shipment size, mandatory appointments, and limits on creating new shipments to some fulfilment centres.
