Who set the postal pricing for market dominant?

The United States Postal Service (USPS) is responsible for setting postal pricing for market-dominant products, subject to approval by the Postal Regulatory Commission (PRC). The USPS proposes pricing changes based on factors such as costs, market conditions, and operational needs. The PRC reviews these proposals to ensure they comply with regulatory standards and promote fair competition. This process helps maintain a balance between the USPS's financial sustainability and service accessibility.
