HS Code 2922.16 – Amino-alcohols, other than those containing more than one kind of oxygen function; their ethers and esters; salts thereof, Diethanolammonium perfluorooctane sulphonate
HS code 2922.16 is the 6-digit subheading for amino-alcohols, other than those containing more than one kind of oxygen function, their ethers and esters, salts thereof, Diethanolammonium perfluorooctane sulphonate. It is used for diethanolammonium perfluorooctane sulphonate, DAPFOS, perfluorooctane sulfonate diethanolamine salt, PFOS-DEA and N-ethylperfluorooctanesulfonamidoethanol.
What HS 2922.16 covers
Diethanolammonium perfluorooctane sulphonate (DAPFOS) is a highly specialized chemical compound falling under this HS code. It is a per- and polyfluoroalkyl substance (PFAS) derivative, primarily used as a surfactant and wetting agent in niche industrial applications. Historically, PFAS compounds like DAPFOS have been valued for their unique properties, such as water and oil repellency, heat resistance, and low friction. However, due to growing environmental and health concerns regarding PFAS persistence and bioaccumulation, the production, use, and trade of these substances are increasingly restricted and regulated globally. Importers and exporters are typically specialized chemical manufacturers and distributors serving industries like electronics, aerospace, and certain coatings, often for legacy applications or in regions with less stringent regulations. Key things to know include the severe regulatory scrutiny and phase-out initiatives worldwide, making its trade complex and often declining, with a strong emphasis on compliance with evolving environmental laws.

Codes often confused with 2922.16
Common mistake. This code might be confused with other perfluorinated compounds (e.g., 2904.99 for other sulfonated derivatives) or other amino-alcohols (2922.19), but 292216 specifically identifies the diethanolammonium salt of perfluorooctane sulphonate.
Top exporters and importers of HS code 292216, 2025
In 2025, the largest exporter of HS code 292216 in UN Comtrade data was Spain, with 45% of world exports; the largest importer in UN Comtrade data was the Netherlands, with 24% 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).
