Import Tips
• Provide spectrographic analysis confirming >40% P2O5 to prevent down-classification; critical for duty calculation
• Bulk shipments require phytosanitary certificate if from regions with phosphate-associated pathogens
• Avoid pitfall of tableting - compressed forms may shift to 3105.60 heading
