Iron or steel, non-threaded articles, n.e.c. in item no. 7318.2.
Classification of steel pins under HS 7318.29
Steel pins, specifically those of a non-threaded nature used for mechanical fastening or alignment, are classified under HS code 731829. This code serves as a residual or "basket" category for non-threaded articles of iron or steel that are not specifically named in other subheadings of the 7318.2 group. Heading 7318 covers a wide array of fasteners, and the 7318.2 series is dedicated to non-threaded items such as washers, rivets, and cotters. When a steel pin does not meet the specific definitions of a spring washer (731821), a standard washer (731822), a rivet (731823), or a cotter/cotter-pin (731824), it falls into 731829. This classification is essential for industrial pins used for alignment, pivoting, or locking mechanisms where no screw threads are present. The material must be iron or steel; pins made of other metals like brass or aluminum are classified under their respective material chapters (e.g., Chapter 74 or 76).

Codes often confused with 7318.29
Common mistake. The most frequent misclassification for steel pins is 731824, which is specifically for cotters and cotter-pins. While many industrial pins look similar to cotters, 731824 is strictly for split pins or wedge-shaped cotters. Another common error is using 731700, which covers nails, tacks, and drawing pins; however, 731700 is intended for fasteners used in construction or stationery, not precision mechanical pins. Furthermore, safety pins and hairpins are excluded from this chapter and are classified under 7319 and 9615 respectively.

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).
