USPS Proposed Rule: Revised Application of Overweight and Oversize Items Fee
AI-generated summary for informational purposes only. Not legal advice. See the original source for the authoritative text.
The United States Postal Service (USPS) has proposed an amendment to the Domestic Mail Manual (DMM) that would revise how overweight and oversize fees are applied to domestic mail and parcels. This proposed rule targets the fee structure governing packages that exceed standard weight or dimensional thresholds set by the USPS. Currently, the DMM outlines specific fee schedules for items deemed overweight or oversize. The proposed change seeks to clarify or restructure when and how these surcharges are triggered, potentially affecting the cost of shipping for a broad range of senders and recipients across the country. The amendment is in the proposed rule stage, meaning it is open for public comment before finalization. Businesses and individuals who regularly ship large or heavy packages through USPS should monitor this rulemaking closely, as finalized changes could alter their shipping cost calculations. This rule was proposed on March 25, 2026, and reflects the USPS's ongoing effort to align fee structures with operational costs associated with handling non-standard packages.
