Import Tips

• Verify shank/thread diameter ≥6 mm via caliper measurement to confirm HTS 7318.15.80.45 classification; smaller sizes shift to 7318.15.20

• Provide mill test certificates proving iron/steel composition and mechanical properties to avoid reclassification as alloy steel under 7318.15.55

• Label with exact dimensions, grade (e.g

• 8.8), and standards like DIN 912 for customs scrutiny
