Washington, DC – Today the Postal Regulatory Commission (Commission) issued its FY 2021 Annual Compliance Determination (ACD) assessing the Postal Service’s compliance with rates and service standards. The Commission is required to issue its ACD 90 days after the filing of the Postal Service’s Annual Compliance Report (39 U.S.C. Section 3653). This ACD is the first compliance review by the Commission following its implementation of new pricing rules for Market Dominant products in FY 2021. Those rules included new rate authority mechanisms, new requirements for workshare discounts and non-compensatory products, and several procedural changes.
