Postal Service Clarifies When the $200 Heavy Package Fee Applies

The Postal Service is finalizing a clarification to its $200 overweight and oversize fee. The rule makes clear that the charge applies to heavy or bulky items found anywhere in the postal network, not just at the post office counter. It also explicitly covers items listed on shipping manifests, which are documents that list the contents of a bulk shipment.

Why it matters: This is mostly an administrative update to ensure consistent billing. It closes a gap in how the fee is applied, particularly for commercial shippers and items caught later in processing. It does not create a new fee or change the weight and size limits; it just standardizes when the existing $200 charge is collected.

Who it affects

• Commercial shippers and freight forwarders who send heavy or oversized packages
