Import Tips
• Verify material composition through lab testing or supplier certification to confirm sintered NdFeB content for proper classification
• Include magnetization status in documentation; unmagnetized articles still qualify if intended for permanent magnet use
• Avoid misclassification as ferrite magnets (8505.19); specify alloy grade like N52 to prevent customs disputes
