Import Tips

Verify graphite content exceeds 50% by weight and confirm semi-colloidal form via lab testing for proper classification

Include Safety Data Sheets (SDS) and technical specs showing non-finished semi-manufacture status to avoid reclassification as finished goods

Check for hazardous material declarations if containing volatile solvents; common pitfall is mislabeling as plain lubricant under 3403
