Import Tips
• Document end-use as agricultural fertilizer to distinguish from industrial chemical imports
• Test for fluorine content if blended, though pure forms avoid 3103 superphosphate confusion
• Use ventilated containers to prevent caking during ocean transport, common in sulfate fertilizers
