N-(2-Hydroxyethyl)-N-methyl Perfluorooctane Sulfonamide
This is a specific perfluorinated sulfonamide compound with the chemical formula featuring a perfluorooctane chain attached to a sulfonamide group substituted with N-methyl and N-(2-hydroxyethyl) groups. It falls under HTS 2935.40.00.00 as a chemically defined organic sulfonamide per the chapter notes for Chapter 29. Primarily used as a fluorosurfactant intermediate in industrial applications.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified primarily by its perfluoroalkyl structure rather than sulfonamide function
Perfluoroalkyl substances may shift to hydrocarbon derivatives heading if sulfonamide not principal characteristic.
If when imported as a mixture or solution for safety/transport with solvents
Chapter notes exclude solutions particularly suited for specific use; mixtures fall under prepared chemical preparations.
If considered an organo-sulfur compound with metal impurities
Organo-sulfur compounds in 2930 take precedence if sulfur directly linked to carbon without sulfonamide dominance.

Import Tips & Compliance
• Verify chemical purity and provide Safety Data Sheets (SDS) for customs clearance; ensure compliance with EPA PFAS regulations due to perfluorinated nature
• Label with exact CAS number if available and avoid retail packaging to prevent reclassification
