HS Code for Steel screws

Steel screws are classified under HS code 7318.15. This code is part of heading 7318, which covers a wide array of fasteners made of iron or steel. Subheading 7318.15 specifically addresses threaded screws and bolts, whether or not they are presented with their nuts or washers. The classification is primarily determined by the presence of external helical threads and the material composition of iron or non-stainless steel. Under the General Rules of Interpretation (GRI), products are classified according to the terms of the headings and any relative section or chapter notes. Heading 7318 distinguishes between threaded and non-threaded articles, and 7318.15 serves as a residual category for various threaded fasteners that do not meet the specific definitions of coach screws (7318.11) or wood screws (7318.12). This code is applicable regardless of the screw's head shape, drive type, or specific industrial application, provided it is a threaded fastener of iron or steel.

Products Included

• Machine screws and hex cap screws
• Socket head cap screws (Allen bolts)
• Carriage bolts and flange bolts
• Studs and threaded rods (if cut to size)
• Set screws and grub screws

Common Misclassification

Steel screws are often misclassified under 7318.12 (wood screws) or 7318.14 (self-tapping screws). Wood screws have a specific tapered thread and pointed tip designed for wood, while self-tapping screws are designed to create their own threads in metal or plastic. If the screw is made of stainless steel, it must be classified under 7318.15.31 or similar regional sub-divisions, though the 6-digit root remains 7318.15. Non-threaded fasteners like rivets (7318.23) are also a common source of confusion.
