Chain; welded link chain, of iron or steel

HS v2017 Code: 731582

About chain; welded link chain, of iron or steel

HS code 731582 covers the import and export of welded link chain made of iron or steel. This type of chain is widely used in a variety of industrial and commercial applications, including material handling, lifting, and securing loads. The chain industry plays a crucial role in supporting the broader manufacturing and logistics sectors, enabling the efficient movement and handling of goods both domestically and internationally.

Production process

The production of welded link chain typically involves a multi-step process. First, the raw materials, such as steel wire or rod, are cut and formed into individual links. These links are then welded together, either manually or through automated welding equipment, to create the continuous chain. The welded links are often heat-treated or galvanized to improve their strength, durability, and corrosion resistance. Quality control measures, such as dimensional inspections and load testing, are employed throughout the manufacturing process to ensure the chain meets industry standards.

Production inputs

The main inputs required for the production of welded link chain include steel wire or rod, welding equipment, and various tools and machinery for the cutting, forming, and assembly of the links. Depending on the specific application, additional inputs such as heat-treating or galvanizing equipment may also be necessary. The availability and cost of these raw materials and production resources can significantly impact the overall competitiveness of the chain manufacturing industry.

Production outputs

The primary output of HS code 731582 is welded link chain, which is used in a wide range of applications. This chain may be consumed by industries such as 842952 Lifting, handling, loading or unloading machinery, 731589 Chain and parts thereof, of iron or steel, n.e.s., and 842542 Jacks; pneumatic, hydraulic, other, among others. The versatility and durability of welded link chain make it an essential component in various supply chain and material handling operations across numerous sectors of the economy.
