Import Tips & Compliance
• Provide Certificate of Analysis (CoA) confirming 99% purity and CAS 141-82-2 to verify classification as chemically defined malonic acid
• Ensure proper Hazard Class 8 labeling (corrosive solid) and include Safety Data Sheet (SDS) for DOT compliance
• Avoid misclassification as mixtures; single-component shipments only under this code
