Import Tips
• Verify zinc content certification (min 85% metallic zinc) and particle size analysis to confirm HTS 7903.90.60.00 classification
• Provide Material Safety Data Sheets (MSDS) for handling hazardous fine powders during customs clearance
• Avoid misclassification as zinc powder by proving vapor condensation method via manufacturer specs
