About HS Code 293510
N-methylperfluorooctane sulphonamide (N-MeFOS) is a specific per- and polyfluoroalkyl substance (PFAS) derivative, historically used in various industrial applications due to its excellent water and oil repellency. While its use has been significantly restricted or phased out in many regions due to environmental and health concerns, it remains relevant for understanding historical trade patterns and for specific, highly controlled applications or as a reference standard. Importers and exporters were typically chemical manufacturers and industries involved in surface coatings, textiles, and fire-fighting foams. Today, trade is minimal and highly regulated, often limited to research or specific industrial uses under strict permits. Key things to know include the global regulatory push to eliminate PFAS compounds, the environmental persistence of N-MeFOS, and the shift towards safer alternatives. Its trade is now largely driven by compliance and environmental monitoring rather than widespread industrial application.
Products Under This Code
N-methylperfluorooctane sulphonamide (N-MeFOS), Perfluorooctane sulfonamide (PFOSA)
Real World Examples
Historical Scotchgard formulations, Fire-fighting foams (AFFF components), Water-repellent textile treatments
Common Misclassification
This code is very specific. It could be confused with other sulfonamides under 2935.90 (other sulfonamides) if the specific N-methylperfluorooctane structure is not identified, or with other PFAS chemicals under different chapters if the sulphonamide functional group is overlooked.
Industry
This code belongs to the Chemicals industry.
Trade Overview
Historically, the United States, European countries, and China were significant in its trade, but current trade is highly restricted globally.
