HTS Code 9902.05.13 classifies a specific chemical compound, 2,2'-Sulfanediylbis[4-methyl-6-(2-methyl-2-propanyl)phenol], also known by its CAS Number 90-66-4. This classification falls under Chapter 99, which pertains to temporary legislation, temporary modifications proclaimed pursuant to trade agreements, and additional import restrictions proclaimed pursuant to Section 22 of the Agricultural Adjustment Act. The explicit reference to its provision within subheading 2930.90.29 indicates that this chemical's import is subject to specific, temporary trade policy measures beyond its standard chemical classification under Chapter 29.

This particular entry within Chapter 99 serves as a temporary tariff modification or restriction for a chemical that would otherwise be classified under Chapter 29, specifically within the broad category of organosulfur compounds. Unlike sibling entries within Chapter 99 which might cover other temporary trade measures, this code is uniquely tied to the specific chemical identified by its HTS description and CAS number. Its purpose is to administer specific trade policies, such as quotas, additional duties, or prohibitions, related to this particular antioxidant, which is often used as a stabilizer in plastics and rubber.

When classifying goods falling under this HTS code, the primary consideration is the presence of 2,2'-Sulfanediylbis[4-methyl-6-(2-methyl-2-propanyl)phenol] and the application of the temporary measures stipulated by Chapter 99. This necessitates careful review of any proclamations or regulations associated with this specific temporary provision to ensure compliance.
