Last updated: April 2026 dataStandard wood screws of iron or steel — excluding the heavy-duty coach screw category — are classified under a single line (7318120000) and serve the construction, cabinetry, furniture, and DIY hardware markets. Taiwan leads US supply for this heading, a reflection of Taiwan's long-established precision fastener manufacturing base, with China and Canada also contributing. Importers sourcing from Taiwan should note that USMCA does not apply, but the competitive pricing from Taiwanese producers has historically made this a stable supply corridor.

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.
