Publication 51 Revision: M-Bag Clarification

Effective April 24, 2008, we are revising Publication 51, International Postal Rates and Fees, to clarify the weight limit for individual items in direct sacks of printed matter to one addressee (M-bags).

While the maximum weight for an M-bag is 66 pounds (including the tare weight of the sack), the maximum weight of individual items within a sack is implied by Universal Postal Union and Postal Service™ standards but is not clearly stated.
