Import Tips

• Label as 'Corrosive, flammable liquid UN 2735'; ensure secondary containment for spill prevention during ocean freight

• Provide NMR spectrum verification; customs may challenge classification if documentation lacks structural confirmation

• Avoid retail packaging over 1L to prevent shift to consumer chemical headings; bulk industrial packaging maintains Chapter 29 status
