9902.10.25 - Mixtures of tall oil mono-, di-, and triglycerides of a kind used as lubricity improvers (CAS No. 97722-02-6) (provided for in subheading 3811.90.00)

This HTS code, 9902.10.25, specifically classifies mixtures of tall oil mono-, di-, and triglycerides. These substances are recognized for their application as lubricity improvers, and the inclusion of their Chemical Abstracts Service (CAS) number (97722-02-6) aids in precise identification. Notably, this temporary provision directs classification back to subheading 3811.90.00, indicating its role as a specific exception or modification within the broader tariff structure.

While the current level of the HTS database, Chapter 99, is dedicated to temporary legislation and modifications, the sibling categories at this level represent a vast array of diverse goods. Unlike other entries within Chapter 99 which may relate to agricultural import restrictions or temporary tariff modifications for various product groups, 9902.10.25 is singular in its focus on a particular chemical mixture with a defined industrial use. It does not pertain to live animals, agricultural products, or manufactured goods found in earlier chapters of the HTS.

As a leaf node, HTS code 9902.10.25 has no further subdivisions. Its classification is therefore determined by the specific composition of tall oil triglycerides intended for use as lubricity improvers, as defined by its description and associated CAS number. Any variations in the composition or intended use of similar tall oil derivatives would necessitate reference to other HTS classifications, potentially within Chapter 38 for prepared chemical products.
