United States Postal Service Shipping Equity Act

This bill allows the U.S. Postal Service to mail alcoholic beverages under specific conditions, primarily affecting registered businesses like wineries, breweries, and retailers. It requires shipments to be delivered directly to individuals aged 21+ with photo ID, prohibits resale, and mandates businesses to register with the Postal Service and prepay state taxes. The bill explicitly states it does not override state, local, or tribal laws banning or regulating alcohol shipments. These changes take effect once USPS issues implementing regulations or within two years of the bill's passage.
