Import Tips
• Verify purity certificate (typically 98%+ min) and include Material Safety Data Sheet (MSDS) as pyrogallol is hazardous
• Ensure packaging complies with UN regulations for toxic solids; label as 'Pyrogallol' per DOT/IATA
• Avoid misclassification as general polyphenols (2907.29.25); provide chemical analysis confirming trihydroxybenzene structure
