U.S. imports of High-Purity Unwrought Magnesium (≥99.8% Mg) (HS 810411) totaled $9.3M in August 2026, imported from 10 countries.
Importers of High-Purity Unwrought Magnesium (≥99.8% Mg) paid $131K in duties in August 2026, an average duty rate of 1.41% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataContaining at least 99.8% magnesium by weight, this grade of unwrought magnesium (8104110000) is distinguished from lower-purity alloy-grade material by its use in chemical synthesis, desulfurization reagents, and specialty reducing applications where trace alloying elements would be detrimental. Israel and Turkey are the leading US import sources, with Brazil and Kazakhstan also supplying the market. Importers should note that the 99.8% purity threshold is a hard classification boundary — material just below that level falls into a different subheading — making certified chemical analysis documentation essential at entry.

A certified mill certificate or chemical analysis report from an accredited laboratory, specifying the magnesium content and listing all impurity elements, is the standard supporting document. CBP may request this at entry to verify the classification boundary. If the analysis shows magnesium content below 99.8%, the material would be classified under the subheading covering other unwrought magnesium, with potentially different duty treatment.
Alloy-grade magnesium (typically 99.5–99.7% Mg) is the workhorse material for die-casting and structural applications, where alloying elements like aluminum and zinc are intentionally added downstream. High-purity magnesium at 99.8%+ is required where those trace elements would cause problems — for example, in Grignard reagent synthesis, in nuclear applications, or as a reducing agent in titanium sponge production. Buyers in these sectors must specify and verify the purity grade, as the two products are not interchangeable despite similar physical appearance.
