HS code for Iron pyrites: 2502.00
Iron pyrites, unroasted.
Classification of iron pyrites under HS 2502.00
Unroasted iron pyrites are classified under HS code 2502.00. This heading is part of Chapter 25, which covers mineral products in their natural state or minimally processed. Iron pyrites (natural iron disulfides) are primarily used for the extraction of sulfur or the manufacture of sulfuric acid. The "unroasted" condition is the defining characteristic for this code. Once the pyrites undergo a roasting process to remove sulfur, they are transformed into "roasted iron pyrites" (iron ore cinders), which are then classified under heading 2601. The classification under 2502.00 is straightforward as it is a specific "eo nomine" heading, meaning the product is mentioned by name. This includes both the brassy-yellow cubic crystals known as "fool's gold" and the more unstable marcasite. The material must not be worked beyond simple breaking, crushing, or sifting to remain in this chapter.

Codes often confused with 2502.00
Common mistake. The primary misclassification occurs with roasted iron pyrites, which belong under 2601.12. Additionally, iron ores like hematite or magnetite are classified in 2601.11. If the pyrites are cut and polished as gemstones, they may fall under 7103, though this is rare for industrial pyrites.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
