9902.03.11 - C7-C9-Alkyl 3-(3,5-di-trans-butyl-4-hydroxyphenyl) propionate (CAS No. 125643-61-0) (provided in subheading 2918.29.65)

This HTS subheading, 9902.03.11, specifically covers C7-C9-Alkyl 3-(3,5-di-trans-butyl-4-hydroxyphenyl) propionate, identified by CAS No. 125643-61-0. This chemical compound is a specific type of antioxidant or stabilizer, typically used in industrial applications to prevent degradation of materials. Its presence within Chapter 99 indicates a temporary modification or specific control mechanism, often related to trade agreements or agricultural adjustments, rather than a standard commodity classification found in earlier chapters.

Distinguishing this classification from its siblings within the HTS Database Root reveals a fundamental difference in scope. The sibling categories (e.g., 0101 for live horses, 0102 for live bovine animals) cover live animals and are located in Section I of the HTS. In contrast, 9902.03.11 falls under Section XXII, which deals with special provisions, temporary legislation, and import restrictions. Therefore, this subheading is not comparable to classifications for tangible agricultural products but rather addresses specific, often time-limited, regulatory measures applied to certain chemical substances.

As this is a leaf node, there are no further subcategories under HTS 9902.03.11. This means that any importation of the described chemical compound falling under this temporary provision will be directly classified here. Classification at this level would typically rely on confirming the identity of the chemical substance through documentation and potentially laboratory analysis, ensuring it precisely matches the description and CAS number provided. The specific purpose of its inclusion in Chapter 99, whether it's a quota, a duty reduction/suspension, or a specific import restriction, would need to be consulted in conjunction with the official HTS annotations for this subheading.
