(a) A person is entitled to an exemption from taxation of raw cocoa and green coffee that the person holds in Harris County.
(b) An exemption granted under this section, once allowed, need not be claimed in subsequent years, and the exemption applies to all raw cocoa and green coffee the person holds until the cocoa’s or the coffee’s qualification for the exemption changes. The chief appraiser may, however, require a person who holds raw cocoa or green coffee for which an exemption in a prior year has been granted to file a new application to confirm the cocoa’s or the coffee’s current qualification for the exemption by delivering a written notice that a new application is required, accompanied by an appropriate application form, to the person.
