9902.06.02 - Copper(2+) bis(2-pyridinethiolate 1-oxide) (CAS No. 14915-37-8) (provided for in subheading 2933.39.27)

This HTS category, 9902.06.02, covers a specific chemical compound: Copper(2+) bis(2-pyridinethiolate 1-oxide), identified by CAS Number 14915-37-8. This substance is classified under the temporary legislation provisions of Chapter 99, indicating it is subject to specific import rules or modifications that are not part of the permanent tariff structure. Its placement here signifies a temporary measure or restriction related to its importation.

As a leaf node within Chapter 99, this category does not have further subdivisions. Its unique HTS code signifies a distinct treatment for this particular copper compound. Unlike the primary chapters of the HTS (Chapters 1-97) which classify goods based on their inherent nature and function, Chapter 99 addresses items that fall under special or temporary tariff provisions, trade agreements, or specific legislative actions like Section 22 of the Agricultural Adjustment Act. Therefore, this classification's primary function is to denote the application of these special rules to Copper(2+) bis(2-pyridinethiolate 1-oxide). The specific nature of its provision within Chapter 99, indicated by its reference to subheading 2933.39.27, suggests it is a controlled substance under temporary measures.
