Import Tips
• Provide FDA Drug Master File if for pharmaceutical end-use to streamline CBP review
• Confirm monomeric content via GC-MS analysis to avoid misclassification as cyclic polymer under later headings
• Declare as hazardous (UN 2606) with proper ventilation requirements for import manifests
