Federal Register Updates

Restricting the Mailing of Replica or Inert Explosive Devices

On January 5, 2010, we published a proposed rule in the Federal Register to clarify that the mailing of replica or inert explosive devices, such as grenades, be sent by Registered Mail™ only.

We invite public comments until February 4, 2010. For more details, go to Postal Explorer at pe.usps.com, and click on Federal Registers Notices in the left frame.

Treatment of Undeliverable Books and Sound Recordings

An advance copy of the final rule Federal Register notice revising the Treatment of Undeliverable Books and Sound Recordings is available on Postal Explorer at pe.usps.com.

The final rule clarifies the disposal or treatment of books and sound recordings that are undeliverable-as-addressed (UAA) in their original packaging. The disposal of these items as waste will simplify handling procedures and reduce costs.
