U.S. imports of magnesium waste and scrap (HS 810420) totaled $7.7M in July 2026, traded with 21 countries.
Last updated: July 2026 dataMagnesium waste and scrap (8104200000) feeds secondary smelters and recyclers that recover magnesium for re-use in die casting and structural alloys, making it a key input for circular-economy supply chains in the automotive and aerospace sectors. Canada dominates US import supply under this heading, with Czech Republic, China, Mexico, and Taiwan also contributing volumes. Because magnesium scrap is highly reactive and subject to DOT hazardous-materials transport regulations, proper packaging, labeling, and shipper declarations are essential compliance steps before import.

Beyond standard CBP entry documents, importers of magnesium scrap must comply with DOT hazardous-materials regulations governing reactive metals, including proper UN packaging codes and shipper's declarations. If the scrap originates from a country subject to trade-remedy orders on magnesium, an AD/CVD scope ruling may also be needed to confirm applicability.
Both waste and scrap fall under the same 10-digit line (8104200000) in the US schedule. CBP generally treats 'waste' as residues from manufacturing processes and 'scrap' as end-of-life or off-spec material, but both are classified identically here. The critical distinction is ensuring the material is not further processed to the point where it would reclassify as unwrought magnesium under 810419.
