Roasted iron pyrites — the calcined residue left after burning iron sulfide (pyrite) ore to recover sulfur dioxide for sulfuric acid production — is classified at a single US tariff line (2601200000) and functions primarily as a low-grade iron source for cement clinker and certain pigment applications. Finland and Romania are the leading suppliers to the US under this heading, reflecting the location of sulfuric acid plants that generate the calcine as a byproduct. Because the material is a processing residue rather than a mined ore, its iron content and trace-element profile vary with the original pyrite source and roasting conditions, which importers should verify against end-use specifications.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Roasted iron pyrites (260120) are the oxidized residue of pyrite combustion, produced as a byproduct of sulfuric acid manufacture, and are classified separately from beneficiated iron ore concentrates (260111). The key distinguishing factor is the thermal treatment: if the material has been roasted to remove sulfur, it belongs in 260120 regardless of its iron content. Supporting documentation such as a production process certificate helps establish correct classification at entry.
The primary end uses are as an iron-bearing raw material in Portland cement clinker production and as a feedstock for iron oxide pigment manufacture. Some steel producers have evaluated it as a supplementary iron unit, but its variable chemistry and trace sulfur content typically limit its role to lower-value applications compared with standard iron ore concentrates.
