The U.S. Postal Service updated its Hazardous, Restricted and Perishable Mail regulations, contained in Publication 52. Pub. 52 (Hazardous, Restricted, and Perishable Mail) provides important information to help mailers determine what may be mailed and how certain items must be packaged to keep the mail safe. It also provides guidance to Postal Service™ employees accepting this mail.

The latest revisions incorporate many, but not all, of the provisions for the preparation and transport of limited and excepted quantities for a very limited number of materials offered by domestic surface and air mail.

The U.S. Postal Service publishes the standards for hazardous, restricted, and perishable mail in Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM®) section 601, “Mailability.” The DMM contains all of our official prices and standards for domestic mail, and it governs all other postal information.

The DMM is available on Postal Explorer® at Persons considering using the U.S. Postal Service to ship hazardous materials are strongly cautioned against doing so, unless they have received special instructions and are familiar with the requirements of the Domestic Mail Manual, International Mail Manual and Publication 52 (Hazardous, Restricted, and Perishable Mail).
