Import Tips & Compliance
• Document exact mixing ratio of MAP to DAP components to validate 3105.40.00 classification over generic 3105.90
• Include soil test recommendations showing phosphorus deficiency to support agricultural end-use declaration
• Avoid retail consumer packaging under 10 kg which would require different heading 3105 retail provisions
