The U.S. Postal Service published a final rule in the Federal Register adopting new mailing standards for Periodicals mail prepared in sacks.
The standards include two new types of sacks -- a three-digit carrier routes sack and a merged three-digit sack -- and a new minimum of 24 pieces for most other sacks. The rule is effective May 11.
