2502.00.00.00 - Unroasted iron pyrites

This HTS category, 2502.00.00.00, exclusively covers unroasted iron pyrites. Iron pyrites, also known as fool's gold, are a specific naturally occurring mineral composed of iron and sulfur (FeS₂). The crucial classification criterion here is that the material must be in its unroasted or unprocessed state. This means it has not undergone any thermal treatment or chemical alteration that would change its fundamental composition for use in industrial processes such as sulfur extraction or iron production.

Given that this is a leaf node, there are no further subdivisions within this specific HTS code. Its uniqueness at this level within Chapter 25 of Section V lies in its precise definition as a raw mineral product. Unlike other entries in Chapter 25, which might cover various salts, sulfur in other forms, earths, stones, plastering materials, lime, or cement, this code is narrowly focused on a singular, specific mineral compound in its raw form. It is distinct from roasted pyrites, sulfur ores, or iron ores that have been subjected to processing or are intended for different primary industrial applications.
