26 CFR 48.4223-1 - Special rules relating to further manufacture.
(a)Purchasing manufacturer to be treated as the manufacturer. For purposes of Chapter 32, a manufacturer or producer to whom an article is sold or resold tax free under section 4221(a)(1) of the Code for use by it in further manufacture shall be treated as the manufacturer or producer of such article. If a manufacturer who purchases an article tax free for further manufacture does not use the article for further manufacture, the sale of the article by it, or its use of the article other than in further manufacture, shall, for purposes of the taxes imposed by Chapter 32 of the Code, be treated as a sale or use of the article by the manufacturer thereof. See paragraphs (b) and (c) of this section for determination of taxable sale price where an article purchased tax free for further manufacture is resold, or used other than in further manufacture.
(b)Computation of tax. Except as provided in paragraph (c) of this section, the tax liability referred to in paragraph (a) of this section shall be based on the price for which the article was sold by the purchasing manufacturer, or, where the manufacturer uses the article for a purpose other than which it was purchased, the tax shall be based on the price at which such or similar articles are sold, in the ordinary course of trade by manufacturers, producers, or importers thereof. See section 4218(e) and § 48.4218-5.
(1) Instead of computing the tax as described under paragraph (b) of this section, the purchasing manufacturer who has incurred liability for tax on its sale or use of an article as provided by paragraph (a) of this section may compute the tax incurred under Chapter 32 by using as the tax base either the price for which the article was sold to it by the first purchaser, if any, or the price for which such article was sold by the actual manufacturer, producer, or importer of such article. The purchasing manufacturer must have in its possession information upon which to substantiate such basis for tax. For purposes of this paragraph, the price for which the article was sold by the actual manufacturer or by the first purchaser shall be determined as provided in section 4216 and the regulations thereunder. However, such price shall not be adjusted for any discount, rebate, allowance, return, or repossession of a container or covering, or otherwise.
(2) The election under this paragraph shall be in the form of a statement attached to the return reporting the tax applicable to the sale or use of the article which gave rise to such tax liability. Such election, once made, may not be revoked.
