Import Tips
• Verify exact N-P content via lab analysis to confirm classification under nitrates/phosphates; mislabeling leads to reclassification
• Include fertilizer registration documents from EPA or equivalent; packages over 10kg must not resemble consumer tablets
• Avoid shipping in aqueous solutions to prevent shifting to liquid fertilizer exclusions in Chapter 31 notes
