9902.05.11 - 4,4'-Sulfanediylbis[5-methyl-2-(2-methyl-2-propanyl)phenol] (CAS No. 96-69-5) (provided for in subheading 2930.90.29)

This HTS category, 9902.05.11, specifically covers the chemical compound 4,4'-Sulfanediylbis[5-methyl-2-(2-methyl-2-propanyl)phenol], identified by its CAS Number 96-69-5. This compound is a bisphenol derivative and is classified under this temporary provision because it is provided for in subheading 2930.90.29, which deals with other organosulfur compounds. The inclusion in Chapter 99 signifies a special or temporary classification status, often related to specific trade agreements or import restrictions.

Unlike the broader categories found at the root level of the HTS database, such as live animals (Chapters 01), this provision is highly specific, focusing on a single, defined chemical substance. Its siblings within Chapter 99 would likely represent other temporary legislative measures or modifications related to international trade, but this particular code targets a precise chemical product rather than general categories of goods. The detailed chemical nomenclature and CAS number ensure unambiguous identification.

As a leaf node within the HTS structure, 9902.05.11 does not have further subdivisions. Its classification is based on the precise chemical identity of the substance. For practical classification purposes, importers must ensure that the imported material precisely matches the chemical structure and identification of 4,4'-Sulfanediylbis[5-methyl-2-(2-methyl-2-propanyl)phenol] (CAS No. 96-69-5) and that it is intended for use or handling under the specific provisions outlined for this temporary category.
