HS code for Sodium fluoride: 2826.19

Fluorides, other than of aluminium.

Classification of sodium fluoride under HS 2826.19

Sodium fluoride is an inorganic chemical compound with the formula NaF, classified under HS code 2826.19. This code falls under the broader heading 2826, which encompasses fluorides, fluorosilicates, fluoroaluminates, and other complex fluorine salts. The classification is determined by the chemical structure of the substance as a binary salt of fluorine. Within Chapter 28, which covers inorganic chemicals, products are organized by their constituent elements and functional groups. Sodium fluoride is specifically categorized under the subheading for other fluorides because the preceding subheadings often specify ammonium or aluminum fluorides. This classification applies to the chemical in its pure or technical form. It is important to note that the physical state, whether powder, crystal, or aqueous solution, does not generally change the HS code, provided it remains a separate chemically defined compound. Sodium fluoride is widely utilized in industrial applications, including water fluoridation, wood preservation, and as a flux in metallurgy. The manufacturing process typically involves the neutralization of hydrofluoric acid with sodium carbonate or sodium hydroxide. According to the General Rules of Interpretation (GRI) 1 and 6, the product is classified based on the terms of the headings and subheadings. However, if the product is prepared for specific retail uses, such as in dental health or as a pesticide, different chapters of the Harmonized System may apply. For instance, medicated toothpastes or specific insecticidal preparations might be moved to Chapters 33 or 38, respectively. Accurate classification requires verifying that the product is not mixed with other substances that would change its character from a separate chemically defined compound to a preparation.

Codes often confused with 2826.19

Common mistake. Sodium fluoride is frequently confused with HS code 2826.11, which some regional tariffs use specifically for sodium fluoride, though 2826.19 is the standard international catch-all for other fluorides. It is also often misclassified under 3306.90 when intended for dental hygiene or 3808.91 when packaged as a retail insecticide. Furthermore, it should not be confused with sodium fluorosilicate, which falls under 2826.90.

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

In 2025, the largest exporter of HS 282619 (the code used for sodium 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).
