HS code for Blind rivets: 7318.23
Iron or steel, non-threaded rivets.
Classification of blind rivets under HS 7318.23
Blind rivets are classified under HS code 7318.23, which falls within Chapter 73 of the Harmonized System, covering articles of iron or steel. Heading 7318 specifically addresses screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter-pins, washers, and similar articles of iron or steel. Within this heading, the code is divided between threaded articles and non-threaded articles. Since blind rivets are mechanical fasteners that do not utilize threads for their securing mechanism, they are categorized under the non-threaded section. Subheading 7318.23 is the specific designation for rivets, excluding those used in specialized applications like cotters. The classification is determined by the material composition (iron or steel) and the functional design (non-threaded fastening). Blind rivets, often referred to as "pop" rivets, consist of a tubular body and a mandrel. During installation, the mandrel is pulled to expand the body, creating a permanent joint. This mechanical action distinguishes them from threaded fasteners like bolts or screws. According to the General Rules of Interpretation (GRI 1), classification is determined by the terms of the headings and any relative section or chapter notes. As these are clearly defined as rivets of iron or steel, 7318.23 is the legally applicable code.

Codes often confused with 7318.23
Common mistake. Blind rivets are frequently misclassified under HS code 7318.15, which covers threaded bolts and screws. This error occurs because both are fasteners, but 7318.15 is strictly for threaded items. Another common error is using 7616.10 for aluminum rivets; while the function is the same, the material composition of the rivet body dictates the chapter. If the rivet is made of aluminum, it must be moved to Chapter 76. Additionally, 7318.24 is sometimes used, but that code is reserved for cotters and cotter-pins, which have a different mechanical function than rivets.

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).
