2826Fluorides; fluorosilicates, fluoroaluminates and other complex fluorine salts

Chapter 28: Inorganic chemicals

Plain-language overview

Use HS-4 2826 when importing or exporting fluorides, such as aluminum fluoride used in aluminum production, or sodium hexafluoroaluminate, commonly known as synthetic cryolite, utilized in aluminum smelting processes. Understanding the specific subheadings can help ensure compliance and avoid customs delays.

When determining the right HS-6 code, consider the composition of the fluoride. For example, HS-6 282612 covers fluorides specifically of aluminum, while HS-6 282619 includes all other fluorides that do not contain aluminum. This distinction is crucial for proper classification and duty assessment.

If your product is sodium hexafluoroaluminate, use HS-6 282630. However, if your product is a complex fluorine salt that doesn't fit the other specific categories, refer to HS-6 282690 for those not elsewhere classified in this heading.
