The term “cotton” means (1) all upland cotton harvested in the United States, and, except as used in
section 2106(e) of this title, includes cottonseed of such cotton and the products derived from such cotton and its seed and (2) imports of upland cotton including the upland cotton content of the products derived from upland cotton (other than industrial products as defined by the Secretary). The term “cotton” shall not, however, include any entry of imported cotton by an importer that has a value or weight less than any de minimis figure as established in accordance with regulations issued by the Secretary. Any de minimis figure as established under this paragraph shall be such as to minimize the burden in administering the assessment provision but still provide for the maximum participation of imports of cotton in the assessment provisions of this chapter.
