HS Code 7318.23 – Iron or steel; non-threaded rivets
HS code 7318.23 is the 6-digit subheading for iron or steel, non-threaded rivets. It is used for solid rivets, blind rivets (pop rivets), tubular rivets, semi-tubular rivets and drive rivets.
What HS 7318.23 covers
This category covers non-threaded rivets made from iron or steel, which are permanent mechanical fasteners used to join two or more pieces of material together. Unlike screws or bolts, rivets create a permanent joint by deforming one end (the "tail") to form a head, securing the materials in a robust and often tamper-resistant manner. They are widely used in applications where high strength, structural integrity, or a permanent connection is required, such as in aerospace, automotive manufacturing, shipbuilding, construction (e.g., structural steel), and sheet metal fabrication. International trade is driven by these industrial demands, with importers typically being large-scale manufacturers, shipbuilders, and construction companies requiring reliable fastening solutions. Exporters are specialized fastener manufacturers, often with capabilities for high-volume production and adherence to stringent quality standards for critical applications. Key considerations for trade include rivet type (e.g., solid, blind, tubular), material grade, head style, diameter, length, and compliance with industry-specific standards (e.g., aerospace specifications).

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).
