Import Tips
• Submit chemical analysis reports showing silicon content to confirm alloy status and prevent reclassification
• Verify no 'further working' like coating occurred, as per Chapter 72 note, which would move to 7206+
• Check for uniform pig shape; irregular lumps may raise questions on 'primary forms' status
