27 CFR § 26.67 - Bond, TTB Form 5120.32 - Wine.
(a) General. Except as provided in paragraph (b) of this section, where a proprietor intends to withdraw, for purpose of shipment to the United States, wine of Puerto Rican manufacture from bonded storage in Puerto Rico on computation, but before payment, of the tax imposed by 26 U.S.C. 7652(a), equal to the tax imposed in the United States by 26 U.S.C. 5041, the proprietor must, before making any such withdrawal, furnish a bond. The proprietor must furnish the bond on TTB Form 5120.32, to secure payment of such tax, at the time and in the manner prescribed in this subpart, on all wine so withdrawn. The bond must be executed in a penal sum not less than the amount of unpaid tax which, at any one time, is chargeable against the bond. The penal sum of such bond must not exceed $250,000, but in no case will the penal sum be less than $500.
(b) Bonds covering wine for nonindustrial use and industrial use -
(1) Nonindustrial use. A proprietor who pays tax on a deferred basis under § 26.112 is not required to furnish a bond under this section to cover shipments of wine for nonindustrial use during any portion of a calendar year for which the proprietor is eligible to use an annual or quarterly return period under § 26.112(b)(2) or (b)(3). For purposes of the preceding sentence, the proprietor is considered to be paying tax on a deferred basis even if the proprietor does not pay tax during every return period as long as the proprietor intends to pay tax in a future period. TTB may require a proprietor who has defaulted on any payment to prepay tax as provided in § 26.112(e).
(2) Industrial use. A proprietor is required to furnish a bond under this section to cover shipments of wine for industrial use even if the proprietor pays tax on a deferred basis under § 26.112 and is eligible to use an annual or quarterly return period under § 26.112(b)(2) or (b)(3).
