HS Code for Fluoroaluminates

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.

Products Included

• 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

Common Misclassification

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.

FAQ

What is the HS code for fluoroaluminates?

The HS code for complex fluoroaluminates, excluding synthetic cryolite, is 2826.90.

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.
