Import Tips
• Verify assay certificate showing tungsten content for accurate quantity reporting per statistical notes, without deductions
• Ensure documentation includes origin certification as many tungsten ores face restrictions or quotas from conflict regions
• Avoid misclassification as slag; confirm it's raw ore concentrate, not industrial residues
