The inbound defect fee is charged when Amazon identifies a compliance problem with units arriving at a fulfillment center. Before 2026, Amazon would often just prep the non-compliant items themselves and charge a prep fee ($0.50–$2.50/unit). That option is gone. Now Amazon charges a defect fee and, in some cases, refuses to receive the items entirely.
2025 vs 2026 rates
| Year | Fee range per unit | Notes |
|---|---|---|
| 2025 | $0.02 – $0.07 | Pre-change baseline |
| 2026 | $0.32 – $5.72 | ~1,600% increase. Exact rate depends on defect type and severity. |

What most brands miss
The 1,600% rate increase is the headline, but the operational change underneath it is more significant. For years, brands with sloppy inbound processes relied on Amazon's prep services as a backstop. That backstop is gone. The brands getting hit hardest are mid-size sellers who outsourced inbound prep to 3PLs that haven't updated their SOPs — and are shipping in 2025 prep standards into a 2026 enforcement environment.
At $5.72/unit on a product with a $3.00 contribution margin, a single shipment of 500 defective units doesn't just wipe the margin — it puts you $1,360 underwater before you've sold a single unit. For brands doing consistent volume, inbound defect fees at the new rates can run into five figures per month before anyone notices.
How to avoid inbound defect fees
- Audit your 3PL's prep SOP against 2026 requirements. Amazon's prep requirements by category are listed at Seller Central > Help > FBA Prep Requirements. Send your 3PL the current requirements document — don't assume they've updated their process since the Jan 1 change.
- Use Amazon's inbound compliance tools before shipping. Check Seller Central's Shipment Summary report after creating a shipment plan. Amazon flags prep requirements per ASIN before you ship.
- Photo-document every outbound shipment. If you get hit with a defect fee you believe is erroneous, photos of correctly prepped items leaving your facility are the strongest dispute evidence.
- Run a pilot shipment for new SKUs. Before scaling inbound volume on a new product, send 50–100 units and verify Amazon receives them without defect flags. Fix the process before you're shipping thousands.
- Review Inbound Performance weekly. Seller Central > Reports > Fulfillment > Inbound Performance. The sooner you catch a defect pattern, the fewer units you send through the broken process.
Frequently asked questions
What is the Amazon inbound defect fee? ▾
A per-unit fee charged when Amazon identifies a compliance problem with your inbound shipment — wrong labeling, missing prep, damaged packaging, incorrect box contents, barcode issues. In 2026 the rates jumped from $0.02–$0.07 to $0.32–$5.72 per unit, a roughly 1,600% increase.
Why did inbound defect fees increase so dramatically in 2026? ▾
Amazon ended FBA prep services at US fulfillment centers on January 1, 2026. Previously, Amazon would prep non-compliant items for a fee. Now every unit must arrive fully prepped — correctly labeled, bagged, bubble-wrapped per category requirements. The 1,600% fee increase is the enforcement mechanism.
What triggers an inbound defect fee? ▾
Common triggers: missing or unreadable FNSKU labels, improper poly bagging (e.g., suffocation warning missing on bags >5 inches), incorrect bubble wrap, box contents not matching the shipment manifest, items that required prep sent unprepped, and carton label errors.
How do I know if I was charged an inbound defect fee? ▾
Check Seller Central > Reports > Fulfillment > Inbound Performance. Amazon will also send you a notification when defects are identified. The fee appears in your Payments report as 'Inbound Defect Fee.'
Can I dispute an inbound defect fee? ▾
Yes, but success rates are low. If you have documentation that the items were correctly prepped (e.g., photos of the outbound shipment from your 3PL), you can open a case through Seller Central. Amazon reviews based on the defect type and your evidence.
Does the inbound defect fee apply to FBA New Selection items? ▾
Prep requirements still apply to new-to-FBA items. The New Selection Program waives the inbound placement fee for the first 100 units, but it does not waive defect fees if those units arrive non-compliant.
