Chain; skid, articulated link chain and parts thereof, of iron or steel

HS v2017 Code: 731520

About chain; skid, articulated link chain and parts thereof, of iron or steel

HS code 731520 covers the import and export of chain, skid, and articulated link chain, as well as their parts, made of iron or steel. This industry plays a crucial role in various sectors, including construction, transportation, and manufacturing, where these chains are used for a wide range of applications, such as lifting, securing, and conveying heavy loads. The global demand for these products is driven by the continued growth of industries that rely on efficient material handling and transportation solutions.

Production process

The production of chain, skid, and articulated link chain involves several key steps. Manufacturers typically start with raw materials, such as steel wire or bar, which are then cut, bent, and welded into the desired chain links. The links are then heat-treated to improve their strength and durability. In some cases, the chains may undergo additional finishing processes, such as galvanization or painting, to enhance their corrosion resistance and aesthetic appeal.

Production inputs

The main inputs required for the production of HS code 731520 products include steel wire or bar, welding equipment, heat-treatment furnaces, and specialized machinery for cutting, bending, and assembling the chain links. Additionally, manufacturers may require various tools, jigs, and fixtures to ensure consistent quality and efficient production. The availability and cost of these raw materials and equipment can significantly impact the overall competitiveness of the industry.

Production outputs

The primary outputs of HS code 731520 are the various types of chain, skid, and articulated link chain, as well as their individual parts. These products are widely used in industries such as 842810 Lifting, handling, loading or unloading machinery, 842833 Other continuous-action elevators and conveyors, for goods or materials, and 731700 (Nails, tacks, drawing pins, corrugated nails, staples (other than those of heading 83.05) and similar articles, of iron or steel), where they are essential for material handling, transportation, and securing heavy loads.
