Import Tips

Verify shank and thread diameter is under 6 mm with calipers to confirm HTS 7318.14.10.60 classification

Provide material test reports proving iron/steel composition; stainless variants may shift to 7318.15

Watch for anti-dumping duties on Asian-origin self-tappers; declare country of melt and pour accurately
