Import Tips
• Provide structural formula and alkyl chain verification (ethyl groups) to confirm inclusion in 2922.19.96.10 subheading
• For bulk liquids, ensure UN-approved packaging per DOT 49 CFR as corrosive liquid (UN 2686)
• Avoid bulk mixtures; separate shipments for pure DEAE prevent reclassification to heading 3824
