26 U.S.C. § 5362

Wine on which the tax has not been paid or determined may, under such regulations as the Secretary shall prescribe, be transferred in bond between bonded premises.

The liability for tax on wine transferred to the bonded premises of a distilled spirits plant pursuant to paragraph (1) shall (except as otherwise provided by law) continue until the wine is used in a distilled spirits product.

For purposes of this chapter, the removal of wine for transfer in bond between bonded premises shall not be treated as a removal for consumption or sale.

For purposes of this subsection, the term “bonded premises” means a bonded wine cellar or the bonded premises of a distilled spirits plant.

without payment of tax for export by the proprietor or by any authorized exporter;

without payment of tax for transfer to any foreign-trade zone;

without payment of tax for use of certain vessels and aircraft as authorized by law;

without payment of tax for transfer to any customs bonded warehouse;

without payment of tax for use in the production of vinegar;

without payment of tax for use in distillation in any distilled spirits plant authorized to produce distilled spirits;

free of tax for experimental or research purposes by any scientific university, college of learning, or institution of scientific research;

free of tax for use by or for the account of the proprietor or his agents for analysis or testing, organoleptic or otherwise; and

free of tax for use by the United States or any agency thereof, and for use for analysis, testing, research, or experimentation by the governments of the several States and the District of Columbia or of any political subdivision thereof or by any agency of such governments. No bond shall be required of any such government or agency under this paragraph.

Notwithstanding any other provision of law, wine entered into customs bonded warehouses under subsection (c)(4) may, under such regulations as the Secretary may prescribe, be withdrawn from such warehouses for consumption in the United States by and for the official or family use of such foreign governments, organizations, and individuals who are entitled to withdraw imported wines from such warehouses free of tax. Wines transferred to customs bonded warehouses under subsection (c)(4) shall be entered, stored, and accounted for in such warehouses under such regulations and bonds as the Secretary may prescribe, and may be withdrawn therefrom by such governments, organizations, and individuals free of tax under the same conditions and procedures as imported wines.

Wine entered into customs bonded warehouses under subsection (c)(4) for purposes of removal under paragraph (1) may be withdrawn therefrom for domestic use. Wines so withdrawn shall be treated as American goods exported and returned.

Wine withdrawn from customs bonded warehouses or otherwise brought into the United States free of tax for the official or family use of foreign governments, organizations, or individuals authorized to obtain wine free of tax shall not be sold and shall not be disposed of or possessed for any use other than an authorized use. The provisions of paragraphs (1)(B) and (3) of section 5043(a) are hereby extended and made applicable to any person selling, disposing of, or possessing any wine in violation of the preceding sentence, and to the wine involved in any such violation.
