Alcoholic Beverages
1. Packages containing alcoholic beverages (wine, beer, or spirits) are accepted for transportation only as a contractual service and only from shippers who are licensed and authorized under applicable laws to ship alcoholic beverages. To receive service for packages containing alcoholic beverages, the shipper must enter into and agree to the provisions set forth in the approved UPS agreement for the transportation of wine, beer or spirits, as applicable. The shipment of alcoholic beverages requires the use of Delivery Confirmation Adult Signature Required service requesting an adult signature for each package containing alcoholic beverages, and the shipper must affix a special UPS alcoholic beverages label to each package. For all U.S. inbound import shipments containing alcoholic beverages, the consignee must be licensed and authorized to receive the alcoholic beverages. UPS does not accept packages containing beer or spirits for delivery to a consumer. It is the responsibility of the shipper to ensure that a package tendered to UPS does not violate any federal, state, provincial or local laws or regulations applicable to the package.
