Import Tips
• Obtain chemical import license and ensure SDS compliance with TSCA pre-manufacture notification if not on inventory
• Verify purity certificate (>98%) as impurities may affect classification; package in UN-approved drums for phosphite hazards
• Avoid misclassification as pesticide intermediate; declare as pure chemical reagent to prevent higher duties
