HS Code 2827.31 – Chlorides; of magnesium
HS code 2827.31 is the 6-digit subheading for chlorides, of magnesium. It is used for magnesium chloride flakes, anhydrous magnesium chloride, food grade magnesium chloride, industrial grade magnesium chloride and de-icing agent.
What HS 2827.31 covers
Magnesium chloride is an important inorganic compound with a broad range of industrial and commercial applications, making it a significant item in international trade. It is primarily imported by countries with cold climates for use as a de-icing agent, often preferred over sodium chloride due to its lower corrosive properties and effectiveness at lower temperatures. Additionally, it finds extensive use in the chemical industry for the production of magnesium metal and other magnesium compounds, and in the textile and paper industries. The pharmaceutical and food sectors also import specific grades for medical applications and as a firming agent or electrolyte. Key considerations in its trade include its various forms (flakes, pellets, liquid) and purity levels, which dictate its suitability for different end-uses. Demand is influenced by seasonal weather patterns, industrial production levels, and health-related applications.

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).
