Technical Grade Magnesium Chloride from China
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.

Import Tips
• Submit assay reports showing magnesium content >90% to confirm technical grade vs. preparations
• Declare correct country of origin; Chinese solar-grade may face AD/CVD duties
• Segregate from food-grade shipments to avoid cross-contamination claims
