U.S. exports of Unroasted Iron Pyrites (HS 250200) totaled $163K in August 2026.
Unroasted Iron Pyrites imports of $28K in August 2026 ran 95% below the year-to-date monthly average of $540K.
Last updated: August 2026 dataIron pyrites (iron disulfide, FeS₂) in its natural, unroasted form is used primarily as a feedstock for sulfuric acid production and as a raw material in the chemical and metallurgical industries. Finland is the leading US import source, reflecting Scandinavia's significant base-metal mining sector, with China and South Africa also among suppliers. Because pyrites are a mineral commodity with no mandatory admissibility review, entry is straightforward, though importers should be aware that Chinese-origin mineral products may be subject to Section 301 tariff considerations.

Roasting iron pyrites in air converts the iron disulfide to iron oxide and releases sulfur dioxide, which is captured to produce sulfuric acid. Once roasted, the residue (iron oxide cinder) is classified differently — typically under iron ore or oxide headings in Chapter 26. The 'unroasted' qualifier in 250200 is therefore a critical processing-stage distinction that determines whether the material belongs here or in a downstream heading.
Iron pyrites are not currently on the US critical minerals list in the same way as graphite or rare earths, so there are no special import licensing or strategic stockpile requirements. However, importers sourcing from China should verify current Section 301 tariff applicability, as mineral products from China have been subject to additional duties depending on their specific classification.
