Import Tips

• Verify purity through lab analysis to confirm it meets gypsum (CaSO4·2H2O) composition and isn't calcined, avoiding misclassification as plaster

• Provide geological source documentation and quarry certificates for customs valuation and origin rules

• Use sturdy bulk bags or containers to prevent breakage; declare moisture content to avoid weight disputes
