HS Code 7318.29 – Iron or steel; non-threaded articles, n.e.c. in item no. 7318.2
HS code 7318.29 is the 6-digit subheading for iron or steel, non-threaded articles, n.e.c. in item no. 7318.2. It is used for dowel pins, clevis pins (without cotter holes), hitch pins, retaining rings and circlips.
What HS 7318.29 covers
This "not elsewhere specified or included" (NESOI) code serves as a residual category for various non-threaded articles of iron or steel that function as fasteners or connectors but do not fit into the more specific categories like spring/lock washers (731821), other washers (731822), rivets (731823), or cotters/cotter-pins (731824). It encompasses a diverse range of specialized or less common non-threaded components, crucial for niche applications in manufacturing, construction, and assembly. These can include various types of pins, rings, and clips designed for specific mechanical functions. Importers typically include specialized machinery manufacturers, custom fabricators, and distributors catering to unique industrial needs, often requiring bespoke fastening or positioning solutions. Exporters are often smaller, specialized component producers or larger manufacturers with diverse product lines capable of custom engineering. Key aspects for trade involve understanding the specific application, material properties (e.g., corrosion resistance, strength), unique designs, and compliance with industry-specific standards, making precise specifications and quality control paramount for these often custom-engineered parts.

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).
