Rules similar to the rules of section 4217 shall apply.
Subparagraph (A) shall not apply to use of an article as material in the manufacture or production of, or as a component part of, another article to be manufactured or produced by him.
For purposes of this subchapter (other than subsection (a)(3)(B)), a person shall not be treated as engaged in the manufacture of any article by reason of merely combining such article with any item listed in paragraph (2).
The items listed in this paragraph are any coupling device (including any fifth wheel), wrecker crane, loading and unloading equipment (including any crane, hoist, winch, or power liftgate), aerial ladder or tower, snow and ice control equipment, earthmoving, excavation and construction equipment, spreader, sleeper cab, cab shield, or wood or metal floor.
An article described in section 4051(a)(1) shall not be treated as manufactured or produced solely by reason of repairs or modifications to the article (including any modification which changes the transportation function of the article or restores a wrecked article to a functional condition) if the cost of such repairs and modifications does not exceed 75 percent of the retail price of a comparable new article.
The Secretary shall prescribe regulations which permit, in lieu of any other certification, persons who are purchasing articles taxable under this subchapter for resale or leasing in a long-term lease to execute a statement (made under penalties of perjury) on the sale invoice that such sale is for resale. The Secretary shall not impose any registration requirement as a condition of using such procedure.
