(A) The term “off-highway business use” means any use by a person in a trade or business of such person or in an activity of such person described in section 212 (relating to production of income) otherwise than as a fuel in a highway vehicle— (i) which (at the time of such use), is registered, or is required to be registered, for highway use under the laws of any State or foreign country, or (ii) which, in the case of a highway vehicle owned by the United States, is used on the highway. (i) Except as otherwise provided in this subparagraph, the term “off-highway business use” does not include any use in a motorboat. (ii) The term “off-highway business use” shall include any use in a vessel employed in the fisheries or in the whaling business. (i) The term “off-highway business use” shall include any use in a vehicle which meets the requirements described in clause (ii). (ii) The requirements described in this clause are— (I) the design-based test, and (II) the use-based test. (iii) For purposes of clause (ii)(I), the design-based test is met if the vehicle consists of a chassis— (I) to which there has been permanently mounted (by welding, bolting, riveting, or other means) machinery or equipment to perform a construction, manufacturing, processing, farming, mining, drilling, timbering, or similar operation if the operation of the machinery or equipment is unrelated to transportation on or off the public highways, (II) which has been specially designed to serve only as a mobile carriage and mount (and a power source, where applicable) for the particular machinery or equipment involved, whether or not such machinery or equipment is in operation, and (III) which, by reason of such special design, could not, without substantial structural modification, be used as a component of a vehicle designed to perform a function of transporting any load other than that particular machinery or equipment or similar machinery or equipment requiring such a specially designed chassis. (iv) For purposes of clause (ii)(II), the use-based test is met if the use of the vehicle on public highways was less than 7,500 miles during the taxpayer’s taxable year. This clause shall be applied without regard to use of the vehicle by any organization which is described in section 501(c) and exempt from tax under section 501(a).

(1) All provisions of law, including penalties, applicable in respect to the tax imposed by section 4081 shall, insofar as applicable and not inconsistent with this section, apply in respect of the payments provided for in this section to the same extent as if such payments constituted refunds of overpayments of the tax so imposed. (2) For the purpose of ascertaining the correctness of any claim made under this section, or the correctness of any payment made in respect of any such claim, the Secretary shall have the authority granted by paragraphs (1), (2), and (3) of section 7602(a) (relating to examination of books and witnesses) as if the claimant were the person liable for tax. (h) The Secretary may by regulations prescribe the conditions, not inconsistent with the provisions of this section, under which payments may be made under this section.
