9902.05.08 - 2-(Methylthio)-4-(trifluoromethyl)benzoic acid (MTBA) (CAS No. 142994-05-6) (provided for in subheading 2930.90.29)

This HTS category, 9902.05.08, specifically covers 2-(Methylthio)-4-(trifluoromethyl)benzoic acid (MTBA), identified by CAS No. 142994-05-6. This compound is provisionally classified under subheading 2930.90.29, indicating its placement within the broader Harmonized Tariff Schedule (HTS) as an organic sulfur compound. The designation within Chapter 99 signifies that this classification is subject to temporary legislation, temporary modifications, or additional import restrictions.

Distinguishing this category from its sibling HTS codes at the root level is straightforward, as Chapter 99 serves a distinct purpose. Unlike Chapters 1 through 98, which classify goods based on their inherent nature, material, or function, Chapter 99 is reserved for special classifications, temporary measures, and statutory provisions that alter the standard tariff treatment or impose specific controls. Therefore, 9902.05.08 does not directly compete with classifications for live animals, agricultural products, or manufactured goods found elsewhere in the HTS; its relevance lies in the specific trade or legislative measures applied to MTBA.

As a leaf node, this classification does not have further subcategories. The specificity of the HTS code, including the Chemical Abstracts Service (CAS) number, indicates that a granular level of detail is required for its classification and subsequent import/export procedures. Importers and exporters dealing with MTBA must refer to the annotations and rulings associated with this specific code to understand applicable duties, quotas, or other regulatory requirements that may be in place under the temporary provisions of Chapter 99.
