This bill amends federal law to permit the United States Postal Service (USPS) to mail alcoholic beverages , establishing conditions for such shipments. It specifies that alcoholic beverages become mailable when sent by a "covered entity," such as a registered winery or brewery, and in compliance with the delivery requirements of the destination state, territory, or district. The USPS is mandated to prescribe regulations ensuring direct delivery to an addressee or authorized agent at least 21 years of age , who must present valid government identification at a postal facility. These regulations will also require that the alcoholic beverages are not for resale and that the sending entity certifies compliance, including with state alcohol taxes. Significantly, the legislation explicitly states that it does not preempt or limit any existing State, local, or Tribal laws that prohibit or regulate the delivery, shipment, or sale of alcoholic beverages, thereby preserving local control. It also grants United States District Courts jurisdiction over claims brought by State, local, or Tribal governments against the USPS for violations of their alcohol laws. The Postal Service would be held liable in a manner similar to a private individual for such violations.
