Import Tips

Verify purity through assay certificates to confirm it meets unroasted iron pyrites definition and avoid misclassification as roasted or processed

Obtain mining origin documentation as pyrites from certain countries may face additional trade restrictions or quotas

Ensure proper hazardous material labeling due to potential sulfur dioxide release if inadvertently heated during transport
