Iron or steel; non-threaded rivets

HS v2022 Code: 731823

About iron or steel; non-threaded rivets

HS code 731823 covers the classification of iron or steel non-threaded rivets, which are an essential fastening component used across a wide range of industries. These small, cylindrical metal fasteners play a crucial role in securing and joining various materials, making them indispensable in the manufacturing, construction, and automotive sectors. The global demand for non-threaded rivets continues to grow, driven by the expanding industrial and infrastructure development activities worldwide.

Production process

Non-threaded rivets are typically produced through a process known as cold heading or cold forging. In this method, a piece of metal wire or rod is cut to the desired length and then fed into a die, where it is pressed and formed into the rivet shape using a series of punches and dies. This cold-working process allows the metal to be shaped without the application of heat, resulting in a strong, durable fastener. The final products may undergo additional finishing steps, such as surface treatment or coating, to enhance their corrosion resistance and aesthetic appeal.

Production inputs

The primary raw material for the production of 731823 iron or steel; non-threaded rivets is steel, which is available in various grades and compositions to meet the specific requirements of different applications. Manufacturers also rely on specialized machinery, such as cold heading machines and stamping presses, to efficiently produce large quantities of rivets. Additionally, various consumables, such as lubricants and cutting tools, are necessary for the smooth operation of the production process.

Production outputs

The 731823 iron or steel; non-threaded rivets produced under this HS code are widely used as fasteners in a variety of industries, including 732690 other articles of iron or steel, 870899 parts and accessories for motor vehicles, and 940320 metal furniture. These rivets are often consumed by manufacturers of machinery, equipment, and various metal-based products that require secure and reliable connections.
