Publication 52, Hazardous, Restricted, and Perishable Mail > 4 Restricted Matter > 42 Intoxicating Liquors > 422 Mailability
Intoxicating liquors having 0.5 percent or more alcoholic content are nonmailable. Taxable liquors (as defined by Chapter 51, Internal Revenue Service Code) with 3.2 percent or less alcohol, including those obtained under a prescription or as a collector’s item, also are nonmailable. The prohibition of the mailing of intoxicating liquors is contained in federal law (18 U.S.C. 1716).
Advertising, promotional, or sales matter that solicits or induces the mailing of intoxicating liquors also is nonmailable. See DMM 601.7.4.1.
A product containing an intoxicating liquor is mailable if it conforms to the applicable requirements of the IRS and the Food and Drug Administration (FDA), and if it is not a taxable alcoholic beverage, poisonous, or flammable.
The following are examples of products that may be mailable:
Intoxicating liquor is exempt from the prohibition against mailing when it is sent between employees of federal or state agencies who have an official use for the liquor, such as for testing purposes. This exemption is based on the intent of the law to prevent liquor from being transported to prohibited jurisdictions for consumption and to ensure that all proper tax revenues are paid.
