9902.02.08 - Potassium 2,2,3,3,4,4,5,5,6,6-decafluoro-1-(pentafluoroethyl)cy- clohexanesulfonate (CAS No. 67584-42-3) (provided for in subheading 2904.99.50)

This HTS category, 9902.02.08, specifically covers Potassium 2,2,3,3,4,4,5,5,6,6-decafluoro-1-(pentafluoroethyl)cyclohexanesulfonate, identified by CAS Number 67584-42-3. This chemical compound falls under the broader scope of Chapter 99, which deals with temporary legislation and modifications, including those proclaimed pursuant to trade agreements and additional import restrictions under Section 22 of the Agricultural Adjustment Act. The "provided for in subheading 2904.99.50" notation indicates its underlying classification within the main HTS structure, suggesting it's a specialized fluorinated derivative of a sulfonate.

As a leaf node, this category does not have further subdivisions. Its distinction from sibling categories within Chapter 99 lies in its precise chemical identity and the specific trade and import restrictions associated with this particular substance. Unlike other temporary or special provisions that might cover broader categories of goods or different types of import restrictions, 9902.02.08 is dedicated solely to this fluorinated potassium sulfonate, likely due to specific trade policy or national security considerations. Its classification here is paramount for ensuring compliance with unique import requirements.
