9902.06.93 - 2-Phenylbenzimidazole-5-sulfonic acid (Ensulizole) (CAS No. 27503-81-7 ) (provided for in subheading 2933.99.79)

This HTS category, 9902.06.93, specifically covers 2-Phenylbenzimidazole-5-sulfonic acid, also known as Ensulizole. This chemical compound is identified by CAS Number 27503-81-7 and is provided for under subheading 2933.99.79. Its primary function is as a UV absorber, commonly utilized in cosmetic and sunscreen formulations to protect the skin from harmful ultraviolet radiation. The classification within Chapter 99 signifies its status under temporary legislation or modifications, highlighting that its tariff treatment may differ from standard classifications.

As a leaf node within the HTS database, this category does not have further subdivisions. Its distinctness from sibling categories is defined by its precise chemical composition and intended application. Unlike the broad range of live animals found in Chapters 1 through 5, or the general chemical classifications in Chapters 28 and 29, this HTS code targets a specific chemical compound with a specialized use, recognized under temporary tariff provisions. Classification under 9902.06.93 is therefore determined by the definitive identification of Ensulizole and its intended import purpose, often linked to specific trade agreements or temporary regulatory measures.
