Iron or steel; non-threaded rivets

HS v2017 Code: 731823

About iron or steel; non-threaded rivets

HS code 731823 covers the classification of iron or steel non-threaded rivets. Rivets are an essential fastening component used across a wide range of industries, from construction and manufacturing to automotive and aerospace. As a fundamental building block for many products and structures, the non-threaded rivet industry plays a crucial role in the broader global economy.

Production process

Non-threaded rivets are typically produced through a metalworking process known as cold heading or cold forming. In this method, a metal wire or rod is fed into a die and struck with a punch, which shapes the rivet head and body. The rivet is then cut to the desired length. This process allows for efficient, high-volume production of consistent, high-quality rivets.

Production inputs

The main inputs required for the production of non-threaded rivets under HS code 731823 include iron or steel wire or rod, as well as specialized metalworking machinery and equipment. Manufacturers may also require various tools, dies, and other ancillary components to facilitate the cold heading process. Additionally, energy sources, such as electricity or compressed air, are necessary to power the production equipment.

Production outputs

The primary output of the non-threaded rivet industry classified under HS code 731823 is, of course, the rivets themselves. These fasteners are then consumed by a wide range of downstream industries, including 731816 Iron or steel; structures and parts of structures, 732690 Other articles of iron or steel, and 870810 (Bumpers and parts thereof (including for motor vehicles)), among others.
