9902.03.13 - Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate (CAS No. 2082-79-3) (provided for in subheading 2918.29.75)

This HTS category, 9902.03.13, specifically covers Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate, also identified by CAS No. 2082-79-3. While the primary HTS structure classifies this chemical under subheading 2918.29.75, this Chapter 99 provision indicates a temporary modification or special treatment related to its importation. These provisions within Chapter 99 are distinct from the core product classifications found in Chapters 1-98, often reflecting temporary trade agreements, import restrictions under specific legislation like Section 22 of the Agricultural Adjustment Act, or other special circumstances.

Unlike the primary product classifications which describe broad categories of goods (e.g., live animals in Chapter 01), this node within Chapter 99 does not describe inherent product characteristics but rather special import conditions applied to a specific chemical substance. Therefore, it does not have direct "sibling" product categories in the traditional sense. Its unique placement signifies that the primary classification of this antioxidant under organic chemical provisions (Chapter 29) is subject to specific, temporary import regulations or modifications, making direct comparison to unrelated goods at the same level impractical.

As this is a leaf node, there are no subcategories to introduce. The classification is definitively established at this level, denoting that Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate, under its specific CAS number, is subject to the particular temporary legislation or modification indicated by this Chapter 99 heading. Classification professionals should refer to the underlying regulations or proclamations associated with this specific temporary provision to fully understand the import requirements and any potential duties or restrictions beyond its standard tariff treatment.
