Import Tips
• Submit HPLC purity certificate (>99%) and origin declaration (natural vs synthetic) for proper alkaloid classification
• DEA registration may be needed if used in controlled substance precursors; watch REACH compliance for EU
• Avoid bulk packaging over 25kg without stabilization; anti-caking agents must not change classification
