Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

7318.15.20Lower: 35% vs 43.5%

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.

7318.15Same rate: 43.5%

If made of stainless steel

Stainless steel variants fall under specific alloy provisions in 7318.15.55, based on material composition.

7318.21.00Lower: 40.8% vs 43.5%

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
