About HS Code 293540

This HS code is dedicated to N-(2-hydroxyethyl)-N-methylperfluorooctane sulphonamide, another specific per- and polyfluoroalkyl substance (PFAS). Similar to other compounds in this class, it was historically valued for its unique chemical properties, such as water and oil repellency, finding applications in various industrial and consumer products. However, due to its environmental persistence, bioaccumulation potential, and associated health risks, global trade and use of this specific sulfonamide are under severe scrutiny and increasing regulatory restrictions. Specialty chemical companies are the primary entities involved in its trade, but the market is contracting significantly as industries seek and adopt safer, non-PFAS alternatives. Strict adherence to international and national environmental regulations is critical for any remaining trade.

Products Under This Code

N-(2-hydroxyethyl)-N-methylperfluorooctane sulphonamide (technical grade), related PFAS intermediates, analytical standards of N-MeFOSE

Real World Examples

Historically used in some DuPont products (e.g., Teflon, though formulations changed), specific research chemicals from specialized suppliers

Common Misclassification

This compound can be confused with other sulfonamides in 2935.90 or other perfluorinated compounds in 2903, particularly if the precise chemical structure is not verified.

Industry

This code belongs to the Chemicals industry.

Trade Overview

China has been a producer, with limited imports occurring in countries with specific, regulated industrial needs.
