Effective December 6, 2018, the Postal Service™ is revising Mailing Standards of the United States Postal Service, International Mail Manual (IMM®) to reflect changes to the Individual Country Listing for Peru.
As a result of a formal request made through the Universal Postal Union via International Bureau Circular 84, dated July 2, 2018, Serpost is adding a prohibition on lithium batteries, liquids, and aerosols, including in misrouted items and transit mail items sent via Peru.
