Products classified under HTS 2827.31.00.00
Magnesium Chloride Hexahydrate
Magnesium chloride hexahydrate (MgCl2·6H2O) is a chemically defined inorganic salt of magnesium, commonly used as a de-icing agent and dust suppressant. It falls under HTS 2827.31.00.00 as a chloride of magnesium, fitting Chapter 28's provisions for metal salts. This crystalline form is the most prevalent commercial variant.
Anhydrous Magnesium Chloride
Anhydrous magnesium chloride (MgCl2) is a pure, water-free form used in industrial processes like titanium production and catalyst manufacturing. Classified under HTS 2827.31.00.00 as a chemically defined chloride of magnesium per Chapter 28 notes. It serves as a key raw material in metal refining.
Magnesium Chloride Flakes
Magnesium chloride flakes are produced by crystallizing MgCl2 solutions for applications in dust control and concrete acceleration. This form is explicitly a chloride of magnesium under HTS 2827.31.00.00, meeting Chapter 28's inorganic salt criteria. Commonly sold in 50-lb bags for road maintenance.
Technical Grade Magnesium Chloride
Technical grade magnesium chloride (95-98% purity) is used in refrigeration brines and paper manufacturing. It qualifies under HTS 2827.31.00.00 as a chemically defined magnesium chloride, distinct from organo-inorganic compounds per Chapter notes. Lower purity than reagent grade but still classifiable here.
Magnesium Chloride Solution 35%
A 35% aqueous solution of magnesium chloride (MgCl2) used for dust suppression on unpaved roads. Despite being in solution, it classifies under HTS 2827.31.00.00 as the defining chemical is magnesium chloride, imported by weight of the compound. Liquid form for spray application.
Pharmaceutical Grade Magnesium Chloride USP
USP-grade magnesium chloride meets pharmacopeia standards for use in IV fluids and supplements. Classified in HTS 2827.31.00.00 as a pure magnesium chloride, even for medicinal applications, per Chapter 28 precedence over Chapter 30. High purity (>99%) with low heavy metals.
Magnesium Chloride for Grignard Reagent Production
High-purity magnesium chloride specifically produced for manufacturing Grignard reagents in organic synthesis. Falls under HTS 2827.31.00.00 as chemically defined magnesium chloride used as chemical intermediate. Anhydrous pellets optimized for metal insertion reactions.
Food Grade Magnesium Chloride
Food-grade magnesium chloride (E511) used as a firming agent in tofu production and cheese making. Classifies under HTS 2827.31.00.00 as the base chemical salt, with food safety certifications. Kosher and Halal certified variants available.
Laboratory Reagent Magnesium Chloride
ACS reagent grade magnesium chloride for analytical chemistry and molecular biology applications like PCR buffers. Ultra-high purity under HTS 2827.31.00.00 as chemically defined salt. Bottled in 500g quantities for lab use.
