Import Tips
• Provide detailed N-P-K ratio analysis; DAP must show phosphorus dominance for correct phosphatic classification
• Anti-dumping duties may apply from certain origins; check Commerce Department scopes before sourcing
• Segregate from organic materials in storage to prevent chemical reactions during ocean transit
