Articles
(a) Duty-free entry; declaration of use; extension of liquidation(1) Entry or withdrawal for consumption. Articles defined as prototypes and meeting the other requirements prescribed in paragraph (b) of this section may be entered or withdrawn from warehouse for consumption, duty-free, under subheading 9817.85.01, Harmonized Tariff Schedule of the United States (HTSUS), on CBP Form 7501 or an electronic equivalent. A separate entry or withdrawal must be made for a qualifying prototype article each time the article is imported/reimported to the United States. (2) Importer declaration(i) Entry accepted as declaration. Entry or withdrawal from warehouse for consumption under HTSUS subheading 9817.85.01 may be accepted by the Center director as an effective declaration that the articles will be used solely for the purposes stated in the subheading. (ii) Proof (declaration) of actual use. If it is believed the circumstances so warrant, the Center director may request the submission of proof of actual use, executed and dated by the importer. The title of the party executing the proof of actual use must be set forth. If proof of actual use is requested, the importer must provide it within three years after the date the article is entered or withdrawn from warehouse for consumption. Liquidation of the related entry may be extended until the requested proof or declaration of actual use is received or until the three-year period from the date of entry allowed for the receipt of such proof has expired. While requested proof of use must be given to CBP within three years of the date of entry, the prototype may continue to be used thereafter for the purposes enumerated in HTSUS subheading 9817.85.01. If requested proof of use is not timely received, the entry will be liquidated as dutiable under the tariff provision that would otherwise apply to the imported article. While there is no particular form for this declaration, it may either be submitted in writing, or electronically as authorized by CBP, and must include the following: (A) A description of the use that is being and/or that has been made of the articles set forth in sufficient detail so as to enable the Center director to determine whether the articles have been entitled to entry as claimed; (B) A statement that the articles have not and are not to be put to any other use after the articles have been entered or withdrawn from warehouse for consumption and prior to the completion of their use under HTSUS 9817.85.01 (also see paragraphs (c) and (d) of this section concerning the disposition(s) to which the articles may be put following their use under HTSUS subheading 9817.85.01); and (C) A statement that the articles or any parts of the articles have not been and are not intended to be sold, or incorporated into other products that are sold, after the articles have been entered or withdrawn from warehouse for consumption and prior to the completion of their use as provided in HTSUS subheading 9817.85.01 (see paragraph (b)(2)(ii) of this section).
