The Postal Regulatory Commission (PRC) is informing the public of the Postal Service's filing of changes in rates not of general applicability for Inbound Parcel Post (at Universal Postal Union rates) and Inbound International Proof of Delivery, effective January 1, 2027, along with related proposed changes to the Mail Classification Schedule (MCS). The filing reflects amendments to Article 33 of the Universal Postal Convention adopted by the UPU Dubai Congress in September 2025, which allow designated operators to establish self-declared 'Inward Land Rates' beginning in calendar year 2027. The Commission invites public comments on whether the filing is consistent with applicable statutes and policies.
