9902.03.17 - Hexadecyl 4-hydroxy-3,5-bis(2-methyl-2-propanyl)benzoate (CAS No. 67845-93-6) (provided for in subheading 2918.29.75)

This HTS category, 9902.03.17, pertains to a specific chemical compound: Hexadecyl 4-hydroxy-3,5-bis(2-methyl-2-propanyl)benzoate, also identified by its CAS number 67845-93-6. This classification falls under Chapter 99, which generally addresses temporary legislation, modifications, and special provisions, often related to trade agreements or agricultural adjustments. The inclusion of this specific chemical under a Chapter 99 provision indicates it is subject to particular import controls or duties that may differ from its standard classification.

While the broader sibling categories within Chapter 99 might cover various temporary measures or restricted goods, this particular entry is highly specific, referencing a unique chemical compound. Unlike the vast array of goods classified under the primary chapters of the HTS (e.g., live animals, machinery, textiles), this node is dedicated solely to this ester derivative of benzoic acid, distinguished by its hexadecyl and bis(2-methyl-2-propanyl) substituents. Its purpose often relates to its antioxidant properties in various industrial applications.

As a leaf node, HTS category 9902.03.17 has no further subcategories. Therefore, classification into this specific code relies entirely on the precise identification of Hexadecyl 4-hydroxy-3,5-bis(2-methyl-2-propanyl)benzoate, often confirmed through its CAS number. The directive to classify it under subheading 2918.29.75 signifies that its primary chemical classification is within the organic compounds section, with the Chapter 99 code overlaying a special trade or regulatory treatment.
