Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If precious metal content exceeds base mineral value
Pyrite with recoverable gold or other precious metals classifies as precious metal ores.
If sold as worked ornamental stones
Polished or cut pyrite specimens become worked monumental or building stone.
If primarily clay impurities with minor pyrite
Low-grade pyrite shale may classify as clays rather than pure iron pyrites.

Import Tips & Compliance
• Include XRF analysis confirming FeS2 composition to differentiate from similar-looking metallic minerals
• For collector specimens, provide certificates of authenticity to avoid gemstone misclassification
• Declare crystal size and purity level; larger pure crystals may face different valuation methods
