Iron or non-alloy steel; wire, plated or coated with base metals (other than zinc)

HS code 721730 covers iron or non-alloy steel wire that has been plated or coated with base metals, excluding zinc. This industry plays a crucial role in the manufacturing and construction sectors, providing essential materials for a wide range of applications. The production and trade of these specialized wire products contribute significantly to the global economy, supporting various industries and infrastructure development.

The production of HS 721730 wire typically involves a multi-step process. First, the base steel wire is drawn to the desired diameter and tensile strength. It is then passed through a plating or coating process, where a thin layer of another base metal, such as copper, nickel, or chromium, is applied to the wire's surface. This coating enhances the wire's corrosion resistance, appearance, and specific functional properties, depending on the application.

The main inputs required for the production of HS 721730 wire include high-quality steel wire rods, plating or coating materials (e.g., copper, nickel, chromium), and specialized machinery for wire drawing, plating, and coating. Additionally, the industry relies on a skilled workforce, energy sources, and efficient logistics to ensure the timely delivery of the finished products.

The primary outputs of HS 721730 are plated or coated steel wires, which are used in a variety of applications, such as 731210 Wire ropes, 731300 Barbed wire, 732010 Springs, and 732020 Helical springs. These specialized wire products are often consumed by industries like construction, automotive, machinery, and infrastructure development, contributing to the overall growth and development of the global economy.
