Import Tips & Compliance
• Include manufacturer's assay report confirming >62% K2O to prevent reclassification during customs exam
• Check for chloride sensitivity in import destination crops; document end-use to avoid agricultural restrictions
• Ensure bulk packaging over 10kg to stay in 3104; retail packs trigger 3105 classification
