Regulatory evidence across markets

None of the 13 markets tracked here holds an imported rule under the name SMITHSONITE.

That is a statement about this inventory, not about the law: no imported rule is not evidence that a substance is permitted. A rule may exist under a different name, under a CAS or EC number this glossary entry does not carry, or in a dataset not yet imported.

Zinc Carbonate

Zinc carbonate appears as a white crystalline solid or powder that is insoluble in water. The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. Used in pharmaceuticals, to make other zinc compounds, as a feed additive. — CAMEO Chemicals
