Import Tips
• Include monomer weight percentage certification; PTMEG must meet 95% ether unit threshold
• Ship in industrial drums/barrels marked 'not for consumer use' to prevent 3923 packaging misclassification
• Beware bulk vs packaged; retail packs may fall under 3923.10 if <38.1cm dimensions per US note
