Import Tips

• Verify shank/thread diameter exceeds 6mm via caliper measurement to confirm 7318.15.80.20 classification; smaller sizes shift to other subheadings

• Include material test certificates (e.g

• alloy steel composition) for customs valuation and anti-dumping checks on steel products

• Avoid misclassification as bolts by ensuring no head protrusion and documenting end-use as fixed-position fasteners
