Self-drilling screws (also called Tek screws) that are designed primarily for metal-to-metal or metal-to-substrate fastening are generally classified under 7318.14 (self-tapping screws) rather than 7318.12. However, if a self-drilling screw is specifically designed and marketed for wood applications with a wood-thread profile, classification as a wood screw may be supportable. The thread form, point geometry, and intended substrate are the key factors; a binding ruling from CBP is recommended when the application is ambiguous.
Taiwan has built a highly specialized fastener manufacturing industry over several decades, with producers offering tight dimensional tolerances, consistent surface treatments, and large-volume capacity at competitive prices. This industrial depth, combined with established logistics relationships with US hardware distributors, has made Taiwan the leading source for standard wood screws even as other Asian suppliers have grown.
