Effective August 15, 2019, the Postal Service™ is revising the Individual Country Listing for Mexico in Mailing Standards of the United States Postal Service, International Mail Manual (IMM®) to note new prohibitions and an observation that Mexico is requiring a health certificate for food supplements.
These revisions are based on a formal request that Correos de México made through the Universal Postal Union via International Bureau Circular 124, dated July 15, 2019.
