Chain; welded link chain, of iron or steel

HS v2022 Code: 731582

About chain; welded link chain, of iron or steel

HS code 731582 covers the classification of welded link chain, a critical component in a wide range of industrial and commercial applications. This type of chain is primarily made of iron or steel and is known for its durability, strength, and versatility. It plays a vital role in various sectors, including manufacturing, construction, transportation, and material handling, making it an essential part of the broader global supply chain ecosystem.

Production process

The production of welded link chain typically involves a multi-step process. First, the raw materials, such as iron or steel wire, are cut and formed into individual links. These links are then welded together using specialized equipment, creating a continuous chain. The welding process ensures a strong and secure connection between the links, enhancing the overall strength and reliability of the final product. Quality control measures are implemented throughout the production process to ensure consistent product performance and compliance with industry standards.

Production inputs

The primary inputs required for the production of welded link chain include iron or steel wire, welding equipment, and various tools and machinery for the cutting, forming, and assembly of the links. Depending on the specific application and desired characteristics, manufacturers may also utilize specialized coatings or treatments to enhance the chain's corrosion resistance, wear resistance, or other properties. Additionally, the production process may require skilled labor, energy sources, and a well-organized supply chain to ensure the timely delivery of raw materials and components.

Production outputs

The primary output of HS code 731582 is welded link chain, which is used in a wide range of applications. This type of chain is commonly found in 842952 Lifting, handling, loading or unloading machinery, 842959 Other lifting, handling, loading or unloading machinery, and 848210 Ball or roller bearings, where it is used for tasks such as hoisting, lifting, and material transportation. The chain's versatility also makes it a valuable component in 731589 Other chain, of iron or steel, where it may be further processed or incorporated into larger assemblies.
