Title 39 › Part IV— MAIL MATTER › Chapter 36— POSTAL RATES, CLASSES, AND SERVICES › Subchapter III— PROVISIONS RELATING TO EXPERIMENTAL AND NEW PRODUCTS › § 3642
The Postal Regulatory Commission can add, remove, or move mail products between the market-dominant and competitive lists. Market-dominant products are ones where the Postal Service has enough market power to raise prices, cut quality, or reduce service without losing much business. Competitive products are everything else. Products that are part of the federal postal monopoly cannot be moved out of the market-dominant list. The Commission must consider whether private companies provide the service, what users think, and how changes will affect small businesses. When the Postal Service asks to add or move a product, it must file and publish a notice explaining why the product meets the rules and, if moving to competitive, that it follows the Commission’s regulations. The Commission must publish updated lists and when they start. Parts of a mail class can be moved without moving every subclass. The Postal Service may not offer physical delivery of letters, printed matter, or packages unless the item is placed in one of the two categories or another law allows it.
