HS Code 2826.90 – Fluorides; fluorosilicates, fluoroaluminates and other complex fluorine salts, n.e.c. in heading no. 2826
HS code 2826.90 is the 6-digit subheading for fluorides, fluorosilicates, fluoroaluminates and other complex fluorine salts, n.e.c. in heading no. 2826. It is used for potassium fluorosilicate, magnesium fluorosilicate, ammonium fluorosilicate, sodium fluorosilicate and potassium tetrafluoroborate.
What HS 2826.90 covers
This 'not elsewhere specified' (n.e.c.) category covers a diverse range of complex fluorine salts, including fluorosilicates, fluoroaluminates (other than sodium hexafluoroaluminate), and other fluorides not specifically classified elsewhere in heading 2826. These compounds are utilized in various specialized applications, such as fluxes in metallurgy, components in welding electrodes, wood preservatives, and in the production of specialty glass and ceramics. Examples include potassium fluorosilicate, magnesium fluorosilicate, and various complex fluoroaluminates. Importers and exporters are typically countries with advanced chemical industries and those requiring these specialized salts for niche manufacturing processes. Trade is driven by specific industrial demands for high-performance materials and chemical reagents, often involving smaller, specialized volumes compared to more common fluorides, reflecting their role in advanced and custom applications.

Codes often confused with 2826.90
Common mistake. This code is a residual category; misclassification occurs when specific fluorides (e.g., 282612, 282619) or synthetic cryolite (282630) are incorrectly placed here, or when simple fluorides are mistaken for complex salts.
Top exporters and importers of HS code 282690, 2025
In 2025, the largest exporter of HS code 282690 in UN Comtrade data was China, with 52% of world exports; the largest importer in UN Comtrade data was Japan, with 33% 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).
