Last updated: April 2026 dataLower-purity unwrought zinc — including casting-grade material — serves die casters, chemical producers, and secondary smelters that do not require the special high grade specification. The US schedule subdivides this heading into a general line (7901120000), a casting-grade subheading (7901121000), and a residual line (7901125000), making correct grade identification critical at entry. Canada and Peru are the leading suppliers, with China also a notable source — and imports from China may be subject to Section 301 tariffs, adding cost and compliance considerations for buyers sourcing from that origin.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The casting-grade line (7901121000) is intended for zinc meeting recognized industry casting-grade specifications, typically with defined allowable impurity levels for lead, cadmium, and iron. Material that does not meet a recognized casting-grade standard but still falls below 99.99% purity would be classified under the residual line 7901125000. Consulting a licensed customs broker and referencing the applicable industry specification is advisable when the grade is borderline.
Yes. Imports of unwrought zinc from China may be subject to Section 301 tariffs in addition to the normal column 1 duty rate. Importers should confirm current Section 301 list coverage and any applicable antidumping orders before finalizing sourcing decisions.
