Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If shank or thread diameter under 6 mm
Screws with smaller diameters are classified separately in 7318.15.20 to distinguish from larger industrial fasteners.
If made of stainless steel
Stainless steel variants fall under specific alloy provisions in 7318.15.55, based on material composition.
If sold as complete washer-nut-screw sets
Assembled sets of screws/bolts with nuts/washers are classified as 'other threaded articles' in 7318.21.

Import Tips & Compliance
• 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
