If any person manufactures, produces, or imports an article (other than a tire taxable under section
4071) and uses it (otherwise than as material in the manufacture or production of, or as a component part of, another article taxable under this chapter to be manufactured or produced by him), then he shall be liable for tax under this chapter in the same manner as if such article were sold by him. This subsection shall not apply in the case of gasoline used by any person, for nonfuel purposes, as a material in the manufacture or production of another article to be manufactured or produced by him. For the purpose of applying the first sentence of this subsection to coal taxable under section
4121, the words “(otherwise than as material in the manufacture or production of, or as a component part of, another article taxable under this chapter to be manufactured or produced by him)” shall be disregarded.
