Import Tips

• Provide Certificate of Analysis (CoA) confirming 99% purity and normal isomer structure to verify classification under 2912.19.25.00

• Ensure proper UN 1129 hazardous material declaration and packaging compliant with DOT/IMDG for flammable liquids

• Avoid misclassification as mixtures; single-isomer purity prevents reclassification under 2912.19.50 (other acyclic aldehydes)
