Import Tips

Verify purity levels and provide certificate of analysis (COA) to confirm classification as chemically defined compound per Chapter 29 notes

Ensure proper hazardous material documentation (UN 1247) for transport as flammable liquid; include stabilizer content details

Avoid misclassification as polymer by confirming <99% polymerization; test samples if bulk shipments vary
