HS Code for Magnesium chloride

Magnesium chloride is classified under HS code 2827.31 as a specific inorganic chemical compound. Chapter 28 of the Harmonized System covers inorganic chemicals, and Heading 2827 is dedicated to chlorides, chloride oxides, chloride hydroxides, bromides, and iodides. Within this heading, the system provides specific subheadings for various metal chlorides. Magnesium chloride (MgCl2) is explicitly assigned to 2827.31. This classification applies regardless of whether the product is in its anhydrous form or as a hydrate, such as the common hexahydrate (MgCl2·6H2O). To be classified here, the substance must be a separate chemically defined element or compound, as per Note 1 to Chapter 28. If the magnesium chloride is presented as a natural brine or unrefined sea salt, it might be classified under Chapter 25 (Heading 2501). However, purified magnesium chloride used for industrial, pharmaceutical, or de-icing purposes is strictly kept within 2827.31. The classification is essential for monitoring the trade of chemical precursors and industrial salts used in the production of magnesium metal and various chemical processes, including dust control and food preparation (as a coagulant for tofu).

Products Included

• Anhydrous magnesium chloride
• Magnesium chloride hexahydrate
• Purified magnesium chloride flakes
• Industrial grade magnesium chloride pellets
• Magnesium chloride solution (chemically pure)

Common Misclassification

Magnesium chloride is sometimes misclassified under 2501.00 if it is part of a natural salt mixture or brine. It may also be confused with 3824.99 if it is part of a prepared chemical mixture for de-icing that contains other additives. Furthermore, if it is prepared as a medicament for retail sale, it would be classified in Chapter 30. However, as a pure chemical compound, 2827.31 is the only correct code.

FAQ

What is the HS code for magnesium chloride?

The HS code for magnesium chloride is 2827.31.

Does this code include magnesium chloride used for de-icing?

Yes, if it is the pure chemical compound. If it is a complex mixture with other anti-caking agents or chemicals, it might fall under 3824.
