Last updated: August 2026 dataCast iron scrap — recovered from engine blocks, pipe fittings, machine castings, and similar gray or ductile iron articles — is a key charge material for cupola and induction furnace foundries producing new castings. Canada and Mexico are the dominant US suppliers, consistent with the integrated North American automotive and heavy-equipment manufacturing base that generates substantial cast iron obsolescence scrap. Imports are subject to Section 232 tariffs, though country-specific exemptions and quota arrangements have historically applied; current status should be verified at entry.

Cast iron is defined by its carbon content — generally above 2% by weight — and its characteristic brittleness and non-malleability. Customs classification relies on the material's composition and origin (e.g., broken castings vs. steel stampings). A mill or laboratory analysis confirming carbon content above the steel threshold supports classification under 7204.10 rather than the steel scrap subheadings.
Most jurisdictions require a scrap metal export license or declaration, and some countries restrict export of certain scrap grades. For US imports, the commercial invoice should identify the scrap grade, estimated composition, and origin. Basel Convention controls do not apply to ferrous scrap, but importers should confirm no country-specific export restrictions affect supply from their source.
