9902.03.25 - Triethylene glycol bis[3-(3-tert-butyl-4-hydroxy-5-methyl- phenyl)propionate] (CAS No. 36443-68-2) (provided for in subheading 2918.99.43)

This HTS classification, 9902.03.25, covers the specific chemical compound Triethylene glycol bis[3-(3-tert-butyl-4-hydroxy-5-methyl- phenyl)propionate], identified by CAS Number 36443-68-2. This classification falls under Chapter 99, which is reserved for temporary legislation, trade agreement modifications, and specific import restrictions. Therefore, this entry does not represent a standard classification for the inherent nature of the chemical but rather signifies a particular regulatory treatment or temporary measure applied to it, as indicated by its provision within subheading 2918.99.43.

As this node is a leaf node within Chapter 99, it does not have further subdivisions. Its distinction from other sibling categories at this level lies in its specific chemical identity and the unique temporary or exceptional import provisions it falls under. Unlike broader categories in Chapter 99 that might cover general trade agreement adjustments or broader restrictions, this HTS code targets a single, precisely identified chemical substance. The practical application of this code is contingent on current trade regulations and proclamations, overriding its standard classification based on chemical properties.
