2902.90.30 - Alkylbenzenes and polyalkylbenzenes

This HTS category, 2902.90.30, encompasses alkylbenzenes and polyalkylbenzenes. These are organic compounds where one or more alkyl groups (saturated hydrocarbon chains) are attached to a benzene ring. This classification is a subdivision within the broader group of "Other" cyclic hydrocarbons.

Distinguishing this category from its siblings, it specifically focuses on compounds characterized by the presence of alkyl substitutions on a benzene ring. For instance, it is distinct from 2902.90.20.00, which covers a list of specific polycyclic aromatic hydrocarbons and other named aromatic compounds like cymene and mesitylene, or 2902.90.40.00, which includes anthracene and a specific difunctionalized benzene. The key differentiating factor here is the direct alkyl-to-benzene bond.

The subcategories under 2902.90.30 further refine the classification. The primary subdivision is for Dodecylbenzene (2902.90.30.10), a specific and commonly traded alkylbenzene used extensively in detergent production. The remaining items within this group fall under "Other" (2902.90.30.50), catering to other alkylbenzenes and polyalkylbenzenes not specifically listed, ensuring comprehensive coverage of these compound types.
