Import Tips
• Provide mill test certificates verifying phosphorus content (typically 18-35%) and iron balance to confirm ferrophosphorus classification
• Ensure documentation distinguishes from ferrosilicon or other ferroalloys to avoid misclassification under different subheadings
• Check for hazardous material declarations as phosphorus content may trigger DOT/IMDG shipping regulations
