Title 39 › PART IV — MAIL MATTER › CHAPTER 36 — POSTAL RATES, CLASSES, AND SERVICES › SUBCHAPTER I — PROVISIONS RELATING TO MARKET-DOMINANT PRODUCTS › § 3622
The Postal Regulatory Commission must create a new system within 18 months to set prices and classes for market‑dominant mail. The system must push the Postal Service to cut costs and work efficiently, keep rates stable and predictable, protect high service quality, let the Postal Service set prices flexibly, ensure enough revenue to stay financially stable, make the rate process clearer and simpler, help mail security, keep rates fair, and divide overall Postal Service costs properly between market‑dominant and competitive products. When making rules, the Commission must consider things like the value of service to senders and recipients, which costs belong to each class of mail, how rate changes affect people and businesses, other ways to send mail, how much mailers prepare mail, simple pricing structures, the need to encourage volume and efficiency, the value or speed needed for different mail types, special classifications and agreements that improve finances or efficiency without harming the market, educational/cultural value, and other policy goals. The system must limit annual rate increases to the change in the Consumer Price Index for All Urban Consumers (not seasonally adjusted) over the most recent 12 months before the Postal Service files notice. Rates should change at regular, predictable times. The Postal Service must give public notice at least 45 days before any rate change, allow Commission review, and answer if the Commission finds the change breaks the CPI limit. The Commission must set procedures for routine changes within the limit and for faster changes in extraordinary cases (the Commission must decide within 90 days after a Postal Service request). The CPI limit applies to each mail class as defined in the Domestic Mail Classification Schedule in effect when the Postal Accountability and Enhancement Act passed. The Postal Service may round rates to whole numbers if that rounding does not push a class’s overall increase past the CPI limit. Any unused rate authority can be used within 5 years, but must be used oldest first and may not make a class’s increase exceed the annual limit by more than 2 percentage points. The Commission must review the system 10 years after enactment and change it if it is not meeting the objectives. Discounts for mail preparation work (workshare discounts) generally cannot be bigger than the costs the Postal Service avoids, except in limited situations (like new services, easing rate shock, educational mail, or when elimination would hurt efficiency), and the Postal Service must report and justify any such discount when it sets it. For the first year after this rule is enacted, existing rate rules and pending proceedings stay under the old law.
