Overview

HTS Code 9902.05.75 specifically covers (S)-1-Anilino-4-methyl-2-methylthio-4-phenylimidazolin-5-one, also known by its common name Fenamidone. This classification is reserved for this particular chemical compound, identified by its CAS Number 161326-34-7, when it is subject to temporary legislative provisions or import restrictions, as indicated by its placement within Chapter 99. The description explicitly references its intended classification under subheading 2933.29.35, which pertains to heterocyclic compounds containing an unfused imidazole ring, further specified by chemical composition.

Given that HTS Code 9902.05.75 is a specific, temporary classification provision, its "sibling" categories at the same level within Chapter 99 would represent other distinct temporary measures, trade agreement modifications, or Section 22 restrictions affecting different goods or products. This particular code is not meant to be confused with the broader categories of live animals (e.g., 0101 to 0105) or other goods that might fall under different chapters of the HTS. Its focus is solely on Fenamidone under specific regulatory circumstances.

As HTS Code 9902.05.75 is a leaf node, it does not have further subcategories. Therefore, classification under this code signifies the definitive categorization for Fenamidone when the conditions for its inclusion in Chapter 99 are met. The specific criteria for classification under this code are entirely dependent on whether the import or exportation of Fenamidone is subject to the temporary legislation, trade agreement modifications, or Section 22 of the Agricultural Adjustment Act, as amended, that this chapter governs.
