About chain; n.e.c. in heading no. 7315, of iron or steel

HS code 731589 covers a wide range of chain products made of iron or steel, excluding those specifically mentioned in other headings of the Harmonized System. These chains are essential components in various industries, from manufacturing and construction to transportation and mining. They play a crucial role in the global economy, enabling the movement of goods, the operation of machinery, and the facilitation of a wide range of industrial processes.

Production process

The production of chains under HS code 731589 typically involves several key steps. First, the raw materials, such as iron or steel, are procured and prepared. The metal is then shaped, cut, and formed into the desired chain links using techniques like stamping, forging, or casting. The individual links are then assembled and connected to create the final chain product. Depending on the specific application, the chains may undergo additional finishing processes, such as heat treatment, coating, or polishing, to enhance their durability, corrosion resistance, or aesthetic appeal.

Production inputs

The main inputs required for the production of chains under HS code 731589 include iron or steel as the primary raw material, as well as various tools and machinery for the shaping, cutting, and assembly of the chain links. Depending on the specific application, additional inputs such as lubricants, coatings, or specialized equipment may be required to ensure the chains meet the necessary performance and safety standards.

Production outputs

The chains produced under HS code 731589 are used in a wide range of applications, including 731511 Roller chain, 731512 Other chain, and 731520 Parts of chain. These chains are essential components in various industries, such as manufacturing, construction, transportation, and mining, where they are used for tasks like lifting, pulling, and securing heavy loads. The output of this industry is a crucial input for many other economic activities, making it an important part of the global supply chain.
