Import Tips
• Submit NMR or GC test results to verify chemical purity and monoalkyl ether structure during customs valuation
• Classify as hazardous material (UN 2709); ensure proper UN-certified packaging to prevent import rejections
• Avoid bulk imports mixed with water beyond note (d) limits, as excess solvent may trigger mixture classification
