Tennessee Code Title 67. Taxes and Licenses § 67-6-219

(a) Notwithstanding other provisions of this chapter, tax is imposed with respect to sales of tangible personal property to common carriers for use outside this state at the rate of three and seventy-five hundredths percent (3.75%).

(b) Persons seeking to make purchases at the reduced rate provided in this section shall apply to the commissioner for a certificate as provided in § 67-6-528. In order to obtain the reduced tax rate, a copy of the certificate provided for by this section or a fully completed Streamlined Sales Tax certificate of exemption shall be given by the common carrier to each dealer from which it intends to make purchases at the reduced rate.

(c) If a common carrier purchases property at the reduced rate and the property is used inside the state or the common carrier fails to keep records as required by the commissioner to establish that property purchased at the reduced rate was not used in this state, but was removed from this state for use and consumption outside this state, then the common carrier shall be liable for tax at the full rate provided by § 67-6-203, regardless of whether the carrier had previously obtained a certificate as provided by this section.

(d) This section does not apply to sales of food and food ingredients, alcoholic beverages, tobacco, candy, dietary supplements, prepared food or fuel.
