Posted on May 13, 2026 by mailomg in Memo 877 // 0 Comments

WASHINGTON, DC — In its filing with the Postal Regulatory Commission, the USPS said it will not increase Priority Mail and Priority Mail Express rates in July.

The existing structure of zoned Retail and Commercial price categories will be maintained.

Dimensional weighting will have its dim divisor changed from 166 to 139 to better align with industry standard.

Two new fees related to the processing of Priority Mail packages containing Hazardous Materials will be introduced. A HazMat Handling Fee for Priority Mail will be $7.50 to cover the costs of manual handling required when HazMat items fly. Also, a HazMat Noncompliance Fee of $50 will be applied to any competitive commercial product when Hazardous Materials are detected but the customer did not appropriately declare and label them.
