Publication 51 Revision: New Mailing Standards and Pricing

Effective May 12, 2008, we are revising Publication 51, International Postal Prices and Fees, to reflect the changes made to Mailing Standards of the United States Postal Service, International Mail Manual (IMM^®).

The changes incorporate the following:

• Shape-based pricing and mailing standards for First-Class Mail International™ service.
• The expansion of the current five country price groups for First-Class Mail International service and Air Mail^® M-bags to nine. This aligns the country price groups for First-Class Mail International service with those for Express Mail International^® and Priority Mail International™ services.
• New commercial base pricing and commercial volume pricing for Express Mail International and Priority Mail International services.
• New prices for mailing services and shipping services.

Please see the IMM for complete international mailing standards.

We will incorporate these revisions into the next printed version of Publication 51 and also into the online version of Publication 51, which is available on Postal Explorer^® at http://pe.usps.com.
