HTS heading 810411 covers unwrought magnesium of 99.8% or higher purity, while 810419 captures all other unwrought magnesium below that threshold. The purity cutoff is determined by the certified chemical composition on the mill certificate, so importers must obtain accurate assay documentation to classify correctly.
Unwrought magnesium has been subject to antidumping duty orders from specific countries in the past. Importers should verify current order scope and applicable AD/CVD case numbers with CBP or a licensed customs broker before entry, as duty liability can be significant and retroactive.
