Import Tips
• Verify purity levels (>99%) through Certificate of Analysis (COA) as impurities may affect classification or duty rates
• Ensure proper UN-approved packaging for flammable solids (UN 3077) to comply with DOT hazardous materials regulations
• Include end-use statements if importing for specific applications like food-contact PET to avoid FDA pre-approval issues
