Fluorochemical Surfactant Building Block N-EtFOSE
>- N-EtFOSE is a fluorinated sulfonamide intermediate used to produce water- and oil-repellent coatings. It matches the exact chemical identity of N-Ethyl-N-(2-hydroxyethyl) perfluorooctane sulphonamide, which is specifically named in tariff item 2935.30.00. As a separate chemically defined organic compound, it falls under Chapter 29 and is classified in this tariff item.
High-Purity EtFOSE for Polymer Synthesis
>- High-purity EtFOSE is a refined grade of N-Ethyl-N-(2-hydroxyethyl) perfluorooctane sulphonamide intended for polymer synthesis. It is a separate chemically defined organic compound, and the added purity does not change its classification. It is therefore classifiable under tariff item 2935.30.00.
Perfluoroalkyl Sulfonamide PFAS Intermediate (EtFOSE)
>- EtFOSE is a perfluoroalkyl sulfonamide intermediate used to synthesize fluorosurfactants and PFAS polymers. It matches the exact chemical description of N-Ethyl-N-(2-hydroxyethyl) perfluorooctane sulphonamide, which is named in tariff item 2935.30.00. As a separate chemically defined compound, it is correctly classified here.
PFOS-Derivative Sulfonamide for Textile Finishing
>- This PFOS-related sulfonamide is N-Ethyl-N-(2-hydroxyethyl)perfluorooctane sulfonamide, used in textile repellency treatments. It is a separate chemically defined organic compound and is specifically named in tariff item 2935.30.00. Therefore, it is classifiable under this tariff item.
Technical Grade Perfluorooctane Sulfonamide (N-Ethyl Hydroxyethyl)
>- Technical grade perfluorooctane sulfonamide contains minor impurities but remains the named N-Ethyl-N-(2-hydroxyethyl)perfluorooctane sulphonamide. Chapter 29 note 1 permits impurities in separate chemically defined organic compounds. Therefore, it is classifiable under tariff item 2935.30.00.
