Import Tips
• Provide mill test certificates confirming alloy composition (Cr, Mo content) and cold-finished status to avoid reclassification
• Verify cross-sectional diameter exceeds 228 mm with precise measurements; common pitfall is mismeasurement leading to wrong subheading
• Declare as 'not further worked' - no coatings or polishing beyond cold-finishing allowed under this code
