Import Tips
• Special EPA waiver required for 'archival reference standards'; cannot be used for application
• Declare exact HCB impurity levels (<0.3%) matching historical formulations in commercial invoice
• Segregate from agricultural chemicals during customs examination to avoid 3808 misclassification
