Title 26 › Subtitle Subtitle D— - Miscellaneous Excise Taxes › Chapter CHAPTER 38— - ENVIRONMENTAL TAXES › Subchapter Subchapter C— - Tax on Certain Imported Substances › § 4672
Names which imported substances are taxed and how the list is kept. A "taxable substance" is any substance the Secretary puts on the taxable list when the importer sells or uses it. A substance goes on that list if it is on the long named list in the law or if, after talking with the Administrator of the Environmental Protection Agency and the Commissioner of U.S. Customs and Border Protection, the Secretary finds that taxable chemicals make up more than 20 percent of the weight or more than 20 percent of the value of the materials used to make it (based on the main way it is produced). The Secretary must add substances that meet the 20 percent tests and may remove a substance only if it meets neither test. "Importer" means the person who brings the taxable substance into the United States for consumption, use, or warehousing. The terms "taxable chemical" and "United States" mean what they mean in section 4662(a). Subsections (a)(3) and (b)(3) of section 7652 do not apply to any tax imposed by section 4671.
