Last updated: April 2026 dataA catch-all heading for naturally occurring mineral substances that do not fit more specific HS chapters, covering commercially distinct materials such as natural cryolite (2530901000), natural chiolite, natural micaceous iron oxides (2530902000), celestite (2530908010), earth colors (2530908015), and residual mineral substances (2530908050, 2530908060). Celestite is the primary commercial source of strontium compounds, while natural micaceous iron oxides are valued as corrosion-resistant pigment inputs. Canada and Mexico are the leading suppliers to the US market, with Japan, Thailand, and Germany also contributing across the diverse product mix within this heading. Correct classification within the six US tariff lines depends on precise mineral identification, as each line carries distinct duty treatment.

Classification depends on the specific mineral identity of the product. Named minerals such as celestite (2530908010) or natural micaceous iron oxides (2530902000) must be classified in their dedicated lines; only truly unspecified mineral substances fall into the residual lines 2530908050 or 2530908060. A licensed customs broker and, where needed, a CBP binding ruling can resolve ambiguous cases.
Celestite (strontianite) is a naturally occurring strontium sulfate mineral classified at 2530908010. It is the principal raw material for strontium carbonate and strontium nitrate used in pyrotechnics, electronics, and specialty glass. Importers should distinguish it from processed strontium compounds, which fall under different HS chapters and carry separate duty treatment.
