9902.10.42 - Branched chain C24 mixed alkylbenzenes (CAS No. 68081-77-6) (provided for in subheading 3817.00.15)

This HTS category, 9902.10.42, specifically covers branched chain C24 mixed alkylbenzenes, identified by CAS No. 68081-77-6. These are synthetic organic compounds often used as intermediates in the production of other chemicals. Their classification within Chapter 99 indicates they are subject to temporary legislation or modifications, and importantly, they are provided for in subheading 3817.00.15 of the general tariff.

Distinguishing this category from its numerous siblings within the broader HTS system is crucial. While other categories at the root level cover a vast array of goods such as live animals (Chapters 01-05), mineral products, or foodstuffs, 9902.10.42 is dedicated to a very specific synthetic chemical substance. Its placement within Section XXII, which deals with special classification provisions and temporary legislation, further separates it from standard product categories. The primary distinguishing factor is the chemical identity and structure of the branched chain C24 mixed alkylbenzenes.

As this is a leaf node, there are no further subcategories within 9902.10.42. Therefore, classification relies on confirming the precise chemical identity of the imported material. Importers must ensure their product matches the description and CAS number provided. Understanding its provision under subheading 3817.00.15 is essential for accurate duty assessment and compliance with any associated temporary measures or restrictions.
