HS Code for PFOS mixtures
PFOS mixtures are classified under HS code 3824.87 because they are chemical preparations or mixtures rather than separate chemically defined compounds. Chapter 38 covers miscellaneous chemical products, and heading 3824 specifically includes chemical products and preparations of the chemical or allied industries not elsewhere specified. Subheading 3824.87 was introduced to track mixtures containing persistent organic pollutants (POPs), including perfluorooctane sulphonic acid, its salts, and its derivatives. This classification applies when PFOS is an ingredient in a functional product, such as a surfactant blend, hydraulic fluid, or coating, provided the mixture is not more specifically described in another heading of the nomenclature.
Products Included
- Firefighting foams containing PFOS
- Hydraulic fluids containing PFOS salts
- Textile treatment preparations with PFOS derivatives
- Metal plating bath additives containing PFOS
- Mist suppressants for chrome plating containing PFOS
Common Misclassification
These mixtures are often misclassified under 2904.31 (the pure acid) or 2904.35 (the pure salts). However, Chapter 29 generally excludes chemical mixtures. Another common error is using HS code 3402.90 for organic surface-active agents. While PFOS often acts as a surfactant, the specific provision for POP-containing mixtures in 3824.87 takes precedence over the general surfactant category according to the General Rules of Interpretation (GRI).
