New Rates for Inbound Small Packets
The Postal Service has proposed new rates for Inbound Letter Post Small Packets (the UPU “E” format) that are scheduled to take effect on January 1, 2027. The Postal Service asked the Postal Regulatory Commission to approve the rates so they can be submitted to the Universal Postal Union by May 1, 2026; the public may comment by April 16, 2026. This change affects anyone who sends or receives small international mail packets.
E-Format Drops ‘Bulky Letters’ Label
Because of UPU amendments adopted at the 2025 Dubai Congress, the Postal Service proposes that the UPU “E” format for letter post will consist only of “small packets” (not “bulky letters”) effective January 1, 2027. The Postal Service proposes removing the term “Bulky Letters” from multiple Mail Classification Schedule sections and making minor wording updates to reflect the UPU rules.
