Import Tips
• Provide REACH/TSCA registration numbers; diamines trigger inventory reporting for polymer manufacturers
• Technical grade requires COA showing <0.1% heavy metals; polymer intermediates face strict impurity limits
• Ship under proper shipping name 'Phenylemdiamines' UN2650; temperature-controlled <40°C to prevent oxidation
