Overview

Amazon lets Fulfillment by Amazon (FBA) sellers request a reimbursement when the fulfillment fees were calculated using incorrect weight or dimension data. Because fees are tiered by size and weight, even a small measurement error can add up to noticeable overcharges. Knowing how to file a claim and the limits of the policy helps sellers protect their margins.

Key Points

• Scope limited to weight/dimension errors — The reimbursement program only covers fees that resulted from inaccurate product measurements; other billing disputes are handled separately.
• Amazon’s measurements are final — If Amazon’s warehouse team records a different weight or size than the seller’s listing, Amazon’s numbers become the official record.
• 90‑day filing deadline — Sellers must submit a claim within 90 days of the fee charge; any request after that period is automatically denied.
• Remeasurement caps — Each SKU can be re‑weighed or re‑sized a maximum of two times in any 60‑day window, and the seller account has a monthly ceiling on total remeasurement requests.
• Physical inventory required — A remeasurement request can only be processed if at least one unit of the product is currently stored in an Amazon fulfillment center.

How the Reimbursement Process Works

1. Identify a suspect charge — Review the FBA fee report and notice that a 12‑oz item was billed at the “Large‑Standard” tier instead of “Small‑Standard.” For example, a seller sees a $0.35 fee per unit that seems high for a lightweight product.
2. Submit a remeasurement request — In Seller Central, navigate to the “Fee Reimbursement” page, select the affected ASIN, and choose “Request remeasurement.” Attach any internal measurement records, such as a scale reading of 11.8 oz and box dimensions of 6 × 4 × 2 in.
3. Amazon re‑weighs and re‑measures — Warehouse staff pull a unit from inventory, place it on a calibrated scale, and measure the package with a standard ruler. If they record 11.5 oz and dimensions of 5.9 × 4.1 × 2.0 in, those figures replace the previous data.
