HS v2022 Code: 731511

About chain; articulated link, roller, of iron or steel

HS code 731511 covers the classification of articulated link, roller chains made of iron or steel. These chains are essential components in a wide range of industrial and commercial applications, including machinery, transportation, and material handling equipment. As a crucial part of power transmission systems, the 731511 chain industry plays a vital role in supporting the broader manufacturing and logistics sectors of the global economy.

Production process

The production of 731511 chains typically involves a multi-step process. First, the raw materials, such as steel alloy, are carefully selected and prepared. The links are then formed through stamping, casting, or forging techniques, ensuring precise dimensions and high strength. The rollers are manufactured separately and attached to the links, creating the articulated structure. Finally, the chains undergo heat treatment and surface finishing processes to enhance their durability and corrosion resistance.

Production inputs

The main inputs required for the 731511 chain industry include high-quality steel alloys, specialized machinery for chain manufacturing, and lubricants or coatings to improve the chains' performance and lifespan. Manufacturers also rely on advanced design software and engineering expertise to optimize the chain's design and ensure compliance with industry standards and safety regulations.

Production outputs

The primary output of the 731511 chain industry is the articulated link, roller chain itself, which is then consumed by a wide range of industries. These chains are used in 842481 Lifting, handling, loading or unloading machinery, 843120 Parts of machinery of heading 8428, 870120 Road tractors for semi-trailers, and 847982 Machines and mechanical appliances having individual functions, not specified or included elsewhere in this chapter, among others. The 731511 chain is a critical component in the efficient operation of these diverse industrial and commercial applications.
