Import Tips
• Verify purity meets chapter note requirements (not chemically defined compounds excluded under note 1(b)); provide chemical analysis certificates
• Ensure product is not packaged for retail (which would shift to 3105); bulk shipments only for this code
• Include soil nutrient analysis or crop application data to avoid misclassification as industrial chemicals
