Import Tips
• Include lab-grade certification and purity assay (>99%) in import docs to justify chemical classification over fertilizer headings
• Package in sealed, moisture-proof containers; hygroscopic nature can cause clumping and quality disputes at entry
• Avoid bulk packaging over 25kg which may trigger additional hazmat fees – check IMDG for phosphate salts
