Import Tips

• Provide chemical analysis certificates confirming TBBS purity (>97%) and benzothiazole structure to avoid misclassification as mixtures under Chapter 38

• Ensure packaging complies with UN regulations for hazardous materials (toxic dust risk) with proper labeling for industrial chemical import

• Verify REACH compliance for EU markets and TSCA registration for US; common pitfall is missing safety data sheets leading to customs delays
