This is an advance notice of the Postal Service's intent to modify some of its International Mailing rules to conform with the new Universal Postal Union (UPU) requirements for certain Letter Post mail, effective January 1, 2018. After lengthy deliberations, UPU member countries voted to identify and separate items by content as documents versus goods, for purposes of adopting a universal, world-wide standard.

In order for the Postal Service to meet this new standard, the contents of First-Class Mail International postcard, letter, and large envelope (flat) mail; International Priority Airmail (IPA) postcard, letter, and large envelope (flat) mail; and International Surface Air Lift (ISAL) postcard, letter, and large envelope (flat) mail will be limited to documents.

Effective January 1, 2018, mailers who wish to mail any type of goods, regardless of shape, must use First Class Package International Service or another available service. Technical details and proposed IMM changes will be published at a later date and before implementation.
