Import Tips
• Label with CAS 603-35-0 and purity percentage; impurities >2% may trigger reclassification review
• Ship under proper DOT/UN 2810 poison label; temperature control may be required for stability
• Maintain Certificates of Analysis showing <0.1% halogen content to prevent misclassification
