SITCSection 2
U.S. imports of iron pyrites, unroasted (SITC 27420) totaled $251K in July 2026, traded with 10 countries.
Importers of Iron Pyrites, Unroasted paid $68K in duties in July 2026 — an effective duty rate of 29% on $236K in dutiable value, based on actual customs collections rather than the published tariff schedule. Iron Pyrites, Unroasted imports of $251K in July 2026 ran 59% below the year-to-date monthly average of $613K.
Last updated: July 2026 dataUnroasted iron pyrites (FeS₂), sometimes called fool's gold in its natural form, is traded primarily as a sulfur source for sulfuric acid production and as a raw material for iron and sulfur chemical manufacturing. The 'unroasted' qualifier is the critical classification boundary: once pyrites are roasted (calcined), the resulting iron oxide cinder is classified elsewhere. Commercial demand for unroasted pyrites has declined in markets where recovered elemental sulfur from petroleum refining is abundant, making it a niche but still-traded mineral commodity.

Unroasted iron pyrites (FeS₂ in its natural mineral state) fall under SITC 27420. Once pyrites are roasted — thermally oxidized to drive off sulfur and produce iron oxide cinder — the product is classified under a different heading covering iron ores or residues. The roasting step fundamentally changes both the chemical composition and the commercial application of the material.
Unroasted pyrites retain commercial use in regions where they are a cost-competitive sulfur source for sulfuric acid plants, particularly where recovered petroleum sulfur is less accessible. They are also used in the production of sulfur dioxide, iron sulfate, and as a minor input in some pigment and chemical manufacturing processes. In most developed markets, however, recovered elemental sulfur has largely displaced pyrites as a sulfur feedstock.
