About chain and parts thereof, of iron or steel

HS code 7315 covers a wide range of chain and chain parts made of iron or steel. These products are essential components in various industries, including construction, mining, transportation, and material handling. Chains are used for a variety of purposes, such as lifting, securing, and transmitting power, making them a crucial element in many industrial and commercial applications. The global demand for these products is driven by the growth of the manufacturing sector, infrastructure development, and the increasing need for efficient material handling systems.

Production process

The production of chains and chain parts under HS code 7315 typically involves several key steps. Manufacturers begin by selecting the appropriate grade of iron or steel, which is then cut, formed, and welded into the desired chain links or components. Heat treatment processes, such as tempering and annealing, are often employed to enhance the strength, durability, and corrosion resistance of the final products. Precision machining and finishing techniques are then used to ensure the chains and parts meet strict quality standards.

Production inputs

The main inputs required for the production of HS code 7315 items include high-quality iron or steel, welding equipment, heat treatment furnaces, and specialized machinery for cutting, forming, and assembling the chain components. Additionally, manufacturers may require various tools, jigs, and fixtures to ensure consistent quality and efficient production. The availability of skilled labor, particularly in welding and metalworking, is also a critical input for this industry.

Production outputs

The primary outputs of HS code 7315 are various types of chains and chain parts, such as 7315.11 Roller chain, 7315.12 Other chain, and 7315.19 Parts. These products are widely used in a range of industries, including 8425.11 Pulley tackle and hoists, powered by electric motor, 8426.41 Derricks; cranes, including cable cranes, and 8431.20 Parts suitable for use solely or principally with the machinery of headings 84.25 to 84.30.
