Chain; articulated link parts, of iron or steel

HS v2017 Code: 731519

About chain; articulated link parts, of iron or steel

HS code 731519 covers the import and export of articulated chain and its component parts, made of iron or steel. This type of chain is widely used in a variety of industrial applications, from material handling equipment to automotive components. As a critical component in many supply chains, the trade of 731519 products plays a significant role in the broader global economy.

Production process

The production of articulated chain and its parts typically involves a multi-step manufacturing process. This includes the initial forming of the individual chain links, often through stamping or casting techniques. The links are then assembled into the final chain structure, which may involve welding, riveting, or other joining methods. Quality control and finishing steps, such as heat treatment or surface coatings, are also commonly employed to ensure the chain's durability and performance.

Production inputs

The primary inputs required for the production of HS code 731519 items include various grades of iron and steel, as well as specialized machinery and equipment for the forming, assembly, and finishing processes. Depending on the specific application, additional inputs such as lubricants, fasteners, and specialized coatings may also be necessary.

Production outputs

The main outputs of the 731519 industry are the articulated chain and its component parts, which are then consumed by a wide range of downstream industries. These include 842952 Machinery for lifting, handling, loading or unloading, 870840 Parts and accessories of motor vehicles, and 731815 Chain and parts thereof, of iron or steel, among others.
