9902.07.31 - (2Z)-3-Isopropyl-2-[(2-methyl-2-propanyl)imino]-5-phenyl- 1,3,5-thiadiazinan-4-one (Buprofezin) (CAS No. 69327-76-0 or 953030-84-7) (provided for in subheading 2934.99.16)

This HTS code, 9902.07.31, specifically covers the chemical compound (2Z)-3-Isopropyl-2-[(2-methyl-2-propanyl)imino]-5-phenyl-1,3,5-thiadiazinan-4-one, commonly known as Buprofezin. This classification is designated for temporary legislative purposes, falling under Section XXII of the Harmonized Tariff Schedule. Buprofezin is an insect growth regulator widely used in agriculture as a pesticide to control various insect pests, particularly in rice and fruit cultivation. Its unique chemical structure and mode of action distinguish it from other chemical compounds classified under different HTS headings.

As a leaf node within Chapter 99, this classification does not have further subcategories. Its specialized nature under temporary legislation means its scope is narrowly defined to this specific compound and its known CAS registry numbers (69327-76-0 or 953030-84-7). While Buprofezin is a chemical substance, its placement in Chapter 99 signifies a specific regulatory or trade agreement-related provision, rather than its primary chemical classification found elsewhere in the HTS, such as under subheading 2934.99.16 which describes related organic compounds. Therefore, importers must ensure accurate documentation to verify the goods as Buprofezin when claiming this specific temporary provision.
