USPS HAZMAT Returns Fees Begin in 2027

Posted on July 29, 2026 by mailomg in Memo 885 // 0 Comments

Effective July 12, 2026, the United States Postal Service introduced a Hazardous Materials (HAZMAT) handling fee and a HAZMAT noncompliance fee for domestic packages. The intent is to ensure packages containing HAZMAT are properly identified with the correct Service Type Code (STC), Service Icon, Barcode Banner Text, and proper UN Label markings. Currently, USPS Returns packages are not subject to these fees.

However, fees will be assessed on USPS Returns packages starting February 1, 2027.

Fees:

Handling Fee – will apply to all domestic retail and commercial packages containing HAZMAT. The fee will be charged at the time of mailing and applied to Priority Mail Express (PME), Priority Mail (PM), USPS Ground Advantage (GA), and Parcel Select (PS). (Currently, USPS Ground Advantage and Parcel Select handling fees are set at $0.00.)
Noncompliance Fee – will apply to domestic commercial HAZMAT packages containing incorrect or mismatched STC, Service Icon, Barcode Banner Text, or UN Label markings. This fee will be assessed through the Census and Automated Package Verification (APV) processes. Fees will be assessed on each noncompliant package and those found to be noncompliant and missing the handling fee will be assessed both fees.

INQUIRIES: During normal business hours M-F (7:00 AM CT – 7:00 PM CT), direct any inquiries or concerns to the Mailing and Shipping Solutions Center (MSSC) via email MSSC@usps.gov or telephone (877) 672-0007.
