Import Tips
• Certificate of Analysis (CoA) must specify exact compound name matching tariff text and purity level to satisfy 'separate chemically defined' requirement
• Label containers with GHS hazard pictograms and UN number (likely UN 1224 for ketones) for proper hazmat declaration
• Avoid bulk packaging over 450L that might trigger mixture classification under Chapter 29 note (e)
