Overview
This HTS category, 9902.09.03, specifically covers specialized dispersions and suspensions used in industrial applications. The core components are complex fluorinated polymers derived from propene, 1,1,2,3,3,3-hexafluoro-, with specific chemical modifications including oxidation, reduction, and hydrolysis. These are further processed into ammonium salts or polymerized forms, with precise weight percentages stipulated for each constituent. The overall composition is a mixture in water, intended for use as a component or additive in various manufacturing processes, often as a surfactant or emulsifier, as indicated by its reference to subheading 3402.11.50.
Unlike the broad categories of live animals and poultry found at the top level of the HTS, this classification pertains to highly specific chemical formulations. Its distinction lies in its complex chemical nature, proprietary manufacturing processes, and intended industrial use, rather than agricultural products or general consumer goods. The highly technical description, including CAS numbers and specific chemical names, underscores its specialized application and differentiates it from more generic chemical classifications.
As a leaf node within Chapter 99, which deals with temporary legislation and special provisions, this classification signifies a specific, potentially time-limited, or conditionally applied tariff treatment. Its presence under Chapter 99 means it is not a permanent classification within the standard HTS structure but rather a temporary modification or restriction enacted under specific trade or agricultural adjustment legislation. Importers must carefully consult the notes and proclamations associated with Chapter 99 to fully understand the scope, duration, and any applicable quantitative limits or duty rates for goods classified under this code.
