HS code for Potassium fluoride: 2826.19

Fluorides, other than of aluminium.

Classification of potassium fluoride under HS 2826.19

Potassium fluoride (KF) is classified under HS code 2826.19. This classification is part of Chapter 28, which covers inorganic chemicals. Heading 2826 is designated for fluorides, fluorosilicates, fluoroaluminates, and other complex fluorine salts. Subheading 2826.19 is a residual category for "other" fluorides that are not specifically mentioned in the preceding subheadings (such as ammonium or sodium fluorides). Potassium fluoride is the primary source of the fluoride ion for applications in chemistry and manufacturing. It is an alkali metal halide and is produced by reacting potassium carbonate with hydrofluoric acid. Its classification is based on its identity as a simple fluoride salt of potassium. It is used in the etching of glass, in the manufacture of insecticides, and as a flux for soldering and welding. The classification remains 2826.19 whether it is in anhydrous form or as a dihydrate.

Covers
  • Anhydrous potassium fluoride powder.
  • Potassium fluoride dihydrate (KF·2H2O).
  • Spray-dried potassium fluoride for specialized chemical reactions.
  • Technical grade KF used as a flux in metallurgy.
  • Potassium fluoride solutions used in wood preservation.
Also under 2826.19
  • Kanto Chemical (reagents)
  • Stella Chemifa (fluorine compounds)
  • Honeywell (fluorine products)
  • Solvay (fluorine chemicals)

Codes often confused with 2826.19

Common mistake. Potassium fluoride is often misclassified under 2826.12, which is specifically for aluminum fluoride, or 2826.90, which covers complex salts like fluorosilicates. It should also not be confused with potassium hydrogen fluoride (potassium bifluoride), which is sometimes classified under 2826.19 but may have specific national codes (like 2826.19.90) depending on the country. Another common error is misclassifying it as a halide of heading 2827 (chlorides, bromides, iodides); however, fluorides have their own dedicated heading in 2826. Finally, if the product is intended for dental use in small retail packaging, it might be argued into Chapter 33, but bulk KF always remains in 2826.19.

Top exporters and importers of HS 282619 (the code used for potassium fluoride), 2025

In 2025, the largest exporter of HS 282619 (the code used for potassium fluoride) in UN Comtrade data was the United States, with 28% of world exports; the largest importer in UN Comtrade data was South Korea, with 14% 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).
