Import Tips & Compliance
• Verify purity certificate and provide Material Safety Data Sheet (MSDS) to comply with DOT and EPA import regulations
• Check for proper UN packaging certification (e.g
• UN1833) to avoid delays at customs
• Avoid misclassification as sodium hydroxide (2815.11); confirm KOH content via lab analysis
