Section 313(g) of the Act, as amended (19 U.S.C. 1313(g)), provides for drawback on imported materials used in the construction and equipment of vessels and aircraft built for foreign account and ownership, or for the government of any foreign country, notwithstanding that these vessels or aircraft may not be exported within the strict meaning of the term.

Other provisions of this part relating to direct identification manufacturing drawback shall apply to claims for drawback filed under this subpart insofar as applicable to and not inconsistent with the provisions of this subpart.

(a) Materials. Section 313(g) of the Act, as amended (19 U.S.C. 1313(g)), applies only to materials used in the original construction and equipment of vessels and aircraft, or to materials used in a “major conversion”, as defined in this section, of a vessel or aircraft. Section 313(g) does not apply to materials used for alteration or repair, or to materials not required for safe operation of the vessel or aircraft.

(b) Foreign account and ownership. Foreign account and ownership, as used in § 313(g) of the Act, as amended (19 U.S.C. 1313(g)), means only vessels or aircraft built or equipped for the account of an owner or owners residing in a foreign country and having a bona fide intention that the vessel or aircraft, when completed, shall be owned and operated under the flag of a foreign country.

(c) Major conversion. For purposes of this subpart, a “major conversion” means a conversion that substantially changes the dimensions or carrying capacity of the vessel or aircraft, changes the type of the vessel or aircraft, substantially prolongs the life of the vessel or aircraft, or otherwise so changes the vessel or aircraft that it is essentially a new vessel or aircraft, as determined by Customs (see 46 U.S.C. 2101(14a)).
