What happened?
A notice posted on Amazon US Seller Forums says that some sellers may see adjustments related to USPS shipping correction charges from September 7 to September 10, 2026. The adjustments concern shipping labels purchased through Amazon Buy Shipping from January 1 to March 31, 2026.
USPS may impose shipping correction charges if a package’s actual dimensions, weight, or return address differs from the information submitted when the label was purchased. The deductions may not appear in the same settlement cycle as the original order, so some sellers may see adjustment records during the period above.
The issue mainly affects US Fulfilled by Merchant (FBM) sellers, particularly those using USPS, selling products with inconsistent packaging dimensions, entering inaccurate weight parameters in bulk listings, or changing return addresses. Sellers can filter for Shipping Services Purchased through Amazon in the Transaction View of the Payments Dashboard, search for “Adjustment,” and check the weight, length, width, height, and return address for each SKU to reduce the risk of further correction charges.
What does this mean for cross-border sellers?
US FBM sellers using USPS and Amazon Buy Shipping may see shipping correction charges outside the original order’s settlement cycle. Check and correct package dimensions, weight, and return-address information promptly to reduce the risk of additional adjustments.
