About HS Code 293530
This HS code is highly specific, designating N-ethyl-N-(2-hydroxyethyl) perfluorooctane sulphonamide. This compound belongs to the broader class of per- and polyfluoroalkyl substances (PFAS), which have historically been used in various industrial applications due to their unique surfactant properties, including in fire-fighting foams, textiles, and surface coatings. However, due to growing environmental and health concerns regarding PFAS persistence and toxicity, trade in this specific sulfonamide, like many other PFAS, is increasingly restricted and regulated globally. Importers and exporters are typically specialty chemical manufacturers, but the market is shrinking as industries transition to PFAS-free alternatives. Compliance with evolving environmental regulations is the primary challenge in its trade.
Products Under This Code
N-ethyl-N-(2-hydroxyethyl) perfluorooctane sulphonamide (technical grade), related PFAS intermediates, analytical standards of N-EtFOSE
Real World Examples
Historically used in some 3M products (e.g., Scotchgard, 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, especially if the full chemical name is not precisely matched.
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.
