Product classification
HS code for Fasteners: 7318.29
Iron or steel, non-threaded articles, n.e.c. in item no. 7318.2.
Classification of fasteners under HS 7318.29
The classification of fasteners under HS code 7318.29 is determined by their material composition and mechanical design. This specific code falls under Heading 7318, which encompasses screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter-pins, washers, and similar articles of iron or steel. Subheading 7318.29 is a residual category for non-threaded articles that are not specifically named in other subheadings of the 7318.2 group. According to General Interpretative Rule (GIR) 1, classification is governed by the terms of the headings and any relative section or chapter notes. Since these items are made of ferrous metal and function as mechanical fasteners without the use of a helical thread, they are excluded from the 7318.1 series (threaded articles). The 7318.29 code is essential for identifying specialized industrial components like non-threaded pins, spacers, and retaining clips that do not fit the specific definitions of rivets or washers. The technical distinction relies on the absence of threading and the fact that the item is not specifically listed under 7318.21 through 7318.24.

Codes often confused with 7318.29
Common mistake. Fasteners are frequently misclassified under HS code 7318.15, which is reserved for threaded bolts and screws; the presence of any helical threading immediately moves the product out of 7318.29. Another common error is using 7318.24, which is specifically for cotters and cotter-pins; if the pin does not meet the technical definition of a cotter, it must remain in 7318.29. Additionally, some importers mistakenly use 7326.90 for other articles of iron or steel, but since 7318 is a more specific heading for fasteners, it takes precedence under GIR 3(a).

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
