HS v2017 Code: 731512

About chain; articulated link, (other than roller), of iron or steel

HS code 731512 covers the classification of articulated link chains, other than roller chains, made of iron or steel. These types of chains are widely used in a variety of industrial and commercial applications, including material handling, power transmission, and automotive systems. As a critical component in many supply chains and manufacturing processes, the production and trade of these chains play an important role in the broader global economy.

Production process

The production of articulated link chains, as described by HS code 731512, typically involves a multi-step process. First, the raw materials, such as steel wire or bars, are cut and formed into individual chain links. These links are then heat-treated to improve their strength and durability. The links are then assembled into the desired chain configuration, often using automated machinery to ensure precision and consistency. Finally, the completed chains may undergo additional finishing processes, such as coating or plating, to enhance their appearance and corrosion resistance.

Production inputs

The main inputs required for the production of articulated link chains under HS code 731512 include steel wire or bars, as well as specialized machinery and equipment for cutting, forming, and assembling the chain links. Additionally, energy sources, such as electricity or natural gas, are needed to power the production processes, and skilled labor is required to operate the machinery and ensure quality control.

Production outputs

The primary output of the industry covered by HS code 731512 is the articulated link chains themselves. These chains are then consumed by a wide range of industries, including 842833 Lifting, handling, loading or unloading machinery, 870840 (Transmission shafts (including camshafts and crankshafts) and cranks; bearing housings and plain shaft bearings; gears and gearing; ball or roller screws; gear boxes and other speed changers, including torque converters), and 848310 (Transmission shafts (including cam shafts and crank shafts) and cranks).
