Last updated: July 2026 dataParticle size and physical form define this heading: magnesium raspings, turnings, and granules must be graded according to size, and magnesium powders are included — all classified under 8104300000. These forms serve as reactive agents in chemical synthesis, pyrotechnics, and metallurgical desulfurization, where controlled surface area and particle distribution are critical performance parameters. Austria and Turkey are leading suppliers to the US market, alongside South Korea, Japan, and Germany. Given magnesium powder's classification as a flammable solid under international transport rules, importers must ensure IMDG/IATA compliance and appropriate storage declarations.

Granules under 810430 must be deliberately sized and graded — typically by sieving to a specified mesh range — for use as a reactive or metallurgical agent. Ungraded chips or turnings that are simply manufacturing residues would more likely classify as waste and scrap under 810420. The seller's product specification sheet and intended end-use are key evidence for the classification decision.
Yes. Magnesium powders are classified as flammable solids (UN 1418) under DOT and IMDG regulations, requiring specific packaging, labeling, and emergency response information. Importers should confirm that the foreign shipper's documentation meets US hazmat import requirements and that the port of entry is equipped to handle the cargo safely.
