HS v2022 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, such as in machinery, automotive parts, and construction equipment. They play a crucial role in the broader economy by facilitating the movement and operation of various systems and devices.

Production process

The production of articulated link chains under 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 connected together using specialized machinery to create the articulated chain structure. The links may undergo additional processing, such as heat treatment or surface finishing, to enhance their strength, durability, and appearance. Finally, the completed chains are inspected and packaged for distribution.

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 various tools and machinery necessary for the cutting, forming, and assembly of the chain links. Additionally, energy sources, such as electricity or natural gas, are needed to power the production equipment. Other inputs may include lubricants, protective coatings, and packaging materials.

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, 842839 Parts of lifting, handling, loading or unloading machinery, 870840 Gear boxes and parts thereof, and 731815 Threaded articles of iron or steel, n.e.s.. The chains are essential components in the operation of various machinery, equipment, and systems across multiple sectors of the economy.
