Iron or non-alloy steel; wire, plated or coated with zinc

HS code 721720 covers iron or non-alloy steel wire that has been plated or coated with zinc. This type of wire is widely used in a variety of industries, from construction and infrastructure to automotive and consumer goods manufacturing. Its corrosion-resistant properties make it a popular choice for applications where exposure to the elements is a concern. As a key component in many supply chains, the production and trade of 721720 wire plays an important role in the broader global economy.

The production of 721720 wire typically involves several key steps. First, the base steel wire is drawn to the desired diameter and tensile strength. It is then passed through a molten zinc bath, where a thin layer of zinc is applied to the surface. This zinc coating provides protection against corrosion and weathering. Finally, the coated wire may undergo additional processing, such as spooling or cutting to length, before being packaged and distributed.

The main inputs required for the production of 721720 wire include high-quality steel wire rod, as well as zinc and various chemicals and lubricants used in the coating process. Specialized wire-drawing equipment and zinc plating machinery are also essential. Additionally, a reliable supply of energy, such as electricity or natural gas, is needed to power the manufacturing facilities.

The primary output of HS code 721720 is zinc-coated steel wire, which is then consumed by a range of downstream industries. This wire may be used in the production of 731210 Wire rope for applications like elevators, cranes, and cable suspension bridges. It is also a key input for 731420 Cloth, grill, netting and fencing, of iron or steel wire, which is used in construction, agriculture, and security fencing. Additionally, 721720 wire can be found in 870821 Safety seat belts and other automotive components.
