HS Code 3824.87 – Chemical products, mixtures and preparations; containing goods specified in Subheading Note 3 to this Chapter; containing perfluorooctane sulphonic acid, its salts, perfluorooctane sulphonamides, or perfluorooctane sulphonyl fluoride
HS code 3824.87 is the 6-digit subheading for chemical products, mixtures and preparations, containing goods specified in Subheading Note 3 to this Chapter, containing perfluorooctane sulphonic acid, its salts, perfluorooctane sulphonamides, or perfluorooctane sulphonyl fluoride. It is used for PFOS-containing firefighting foams (for disposal), surface treatment agents (historical, for disposal), analytical standards of PFOS, specialized industrial coatings (historical, for disposal) and contaminated waste containing PFOS.
What HS 3824.87 covers
This HS code pertains to chemical products, mixtures, and preparations containing perfluorooctane sulphonic acid (PFOS), its salts, sulphonamides, or sulphonyl fluoride, as specified in Subheading Note 3 to Chapter 38. PFOS and its derivatives are a class of Per- and Polyfluoroalkyl Substances (PFAS) recognized as Persistent Organic Pollutants (POPs) due to their environmental persistence, bioaccumulation, and potential health impacts. Historically used in firefighting foams, surface treatments, and industrial coatings, their international trade is now severely restricted or banned under the Stockholm Convention. Current trade primarily involves highly specialized, authorized applications, remediation of contaminated sites, or environmentally sound disposal. Importers and exporters are typically specialized chemical companies, environmental remediation firms, and analytical laboratories in countries with advanced chemical industries and strict environmental regulations.

Codes often confused with 3824.87
Common mistake. This code covers mixtures, not the pure chemicals (e.g., 2904.90 for PFOS acid) or articles treated with them (e.g., textiles in Chapter 59). The 'mixture' aspect is crucial for proper classification.
Top exporters and importers of HS code 382487, 2025
In 2025, the largest exporter of HS code 382487 in UN Comtrade data was the United States, with 39% of world exports; the largest importer in UN Comtrade data was Egypt, with 32% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
