Import Tips
• Submit mill test certificates confirming C67S composition and patenting heat treatment to verify HTS classification
• Measure diameter precisely; even slight deviation to ≥1.5 mm shifts to 7217.10.8035 subheading
• Declare as 'not further worked' beyond heat treatment/polishing per Chapter 72 definition to avoid Chapter 73
