About HS Code 293550
This HS code covers perfluorooctane sulphonamides (PFOS) and their derivatives, which are a specific class of synthetic organic chemicals known for their unique properties like water and oil repellency. Historically, these compounds were widely used in various industrial applications, including fire-fighting foams, surface coatings for textiles and paper, and in some specialized chemical processes. However, due to their persistence in the environment, bioaccumulation, and potential toxicity, many countries have implemented strict regulations or outright bans on their production and use. International trade in these substances is now highly restricted, primarily involving specialized chemical manufacturers and distributors for legacy applications or for destruction. Importers and exporters must navigate complex environmental and health regulations, making compliance a critical aspect of any trade activity. The market for these specific compounds is shrinking due to global efforts to phase out persistent organic pollutants.
Products Under This Code
Perfluorooctane sulfonic acid (PFOS), Potassium perfluorooctane sulfonate, Ammonium perfluorooctane sulfonate, Lithium perfluorooctane sulfonate, N-Ethylperfluorooctane sulfonamidoethanol
Real World Examples
3M (historically Scotchgard), DuPont (historically Teflon), Chemours, Daikin, Solvay
Common Misclassification
These can be confused with other sulphonamides under 293590, or other fluorinated organic compounds in Chapter 29, particularly if their specific perfluorooctane structure is not clearly identified.
Industry
This code belongs to the Chemicals industry.
Trade Overview
Trade is heavily restricted globally, with major chemical-producing nations like China and the EU having strict controls on their import and export.
