Product classification
HS code for Fluoroaluminates: 2826.90
Fluorides, fluorosilicates, fluoroaluminates and other complex fluorine salts, n.e.c. in heading no. 2826.
Classification of fluoroaluminates under HS 2826.90
Fluoroaluminates are inorganic chemicals classified under HS code 2826.90. This code falls within Chapter 28, which encompasses inorganic chemicals, precious metals, and rare-earth metals. Specifically, heading 2826 covers fluorides, fluorosilicates, fluoroaluminates, and other complex fluorine salts. Fluoroaluminates are complex salts where aluminum and fluorine form a coordinated anion. The classification is driven by the chemical composition of the substance. Since 2826.12 covers simple aluminum fluorides and 2826.30 covers sodium hexafluoroaluminate (synthetic cryolite), the 2826.90 code serves as the residual category for other complex fluoroaluminate salts not specifically named elsewhere in the heading.
- Covers
- Potassium fluoroaluminate (used as flux in aluminum brazing)
- Ammonium fluoroaluminate
- Cesium fluoroaluminate
- Complex fluorine salts containing aluminum and other cations
- Synthetic fluoroaluminate compounds for industrial metallurgy
- Also under 2826.90
- Solvay (fluorine chemicals)
- Honeywell (fluorine products)
- Stella Chemifa (fluorine compounds)
- Merck KGaA (specialty chemicals)
Codes often confused with 2826.90
Common mistake. Fluoroaluminates are often confused with simple aluminum fluoride, which is classified under 8526.12. The distinction lies in whether the substance is a simple salt or a complex salt. Additionally, natural cryolite (a natural fluoroaluminate) is classified under 2503.00 as a mineral product, whereas the synthetic versions must remain in Chapter 28. Importers also occasionally confuse these with aluminum ores (2606.00) or refined aluminum metal (7601), though the chemical nature of fluoroaluminates as salts makes Chapter 28 the only appropriate section.
Top exporters and importers of HS 282690 (the code used for fluoroaluminates), 2025
In 2025, the largest exporter of HS 282690 (the code used for fluoroaluminates) 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.
Figures cover everything classified under HS 282690, not only fluoroaluminates.

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).

Questions about fluoroaluminates
What is the HS code for Fluoroaluminates?
The HS code for Fluoroaluminates is 282690 (Fluorides; fluorosilicates, fluoroaluminates and other complex fluorine salts, n.e.c. in heading no. 2826). The HS code for complex fluoroaluminates, excluding synthetic cryolite, is 2826.90.
How do I classify Fluoroaluminates for customs?
Fluoroaluminates is classified under HS code 282690 — Fluorides; fluorosilicates, fluoroaluminates and other complex fluorine salts, n.e.c. in heading no. 2826. This is a 6-digit subheading level code.
Is synthetic cryolite included in this specific code?
No, synthetic cryolite (sodium hexafluoroaluminate) has its own specific subheading, 2826.30, and should not be classified under 2826.90.
Which countries are the top exporters of fluoroaluminates (HS 282690)?
In 2025, the top exporters of HS 282690 (the code used for fluoroaluminates) in UN Comtrade data were China ($209M, 52% of world exports), Germany ($68M) and South Korea ($41M). World exports came to about $399M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of fluoroaluminates (HS 282690)?
In 2025, the top importers of HS 282690 (the code used for fluoroaluminates) in UN Comtrade data were Japan ($161M, 33% of world imports), the United States ($96M) and Poland ($40M). World imports came to about $485M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Is the HS code for Fluoroaluminates the same in all countries?
The base HS code 282690 for Fluoroaluminates is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.
What is the NCM code for fluoroaluminates in Brazil?
Brazil splits HS 282690 into 3 NCM codes, so the right one for fluoroaluminates depends on the product's details: 2826.90.10 (Potassium fluoroaluminate), 2826.90.20 (Sodium or potassium fluorosilicates), 2826.90.90 (Other complex fluorine salts).
