About copper; wire, of refined copper, of which the maximum cross-sectional dimension is 6mm or less

HS code 740819 covers the trade and production of refined copper wire with a maximum cross-sectional dimension of 6mm or less. This type of copper wire is a critical component in a wide range of industries, from electrical and electronics to construction and automotive. Its versatility and conductivity make it an essential material for the global economy, supporting the development of infrastructure, technology, and manufacturing across the world.

Production process

The production of copper wire under HS code 740819 typically involves a multi-step process. First, refined copper is melted and cast into billets or rods. These are then drawn through a series of dies to reduce the diameter and increase the length, creating the thin copper wire. Annealing may be used to soften the wire and improve its ductility. Finally, the wire is spooled or coiled for distribution and further processing.

Production inputs

The main inputs required for the production of HS code 740819 copper wire include refined copper, drawing dies, and specialized wire-drawing equipment. Refined copper is the primary raw material, which must meet strict purity standards to ensure the wire's conductivity. The drawing dies used to reduce the wire diameter are made from tungsten carbide or other durable materials. Additionally, the wire-drawing machines themselves, including capstans, rollers, and tensioning systems, are critical pieces of production equipment.

Production outputs

The primary output of HS code 740819 is refined copper wire with a maximum cross-sectional dimension of 6mm or less. This wire is then consumed by a variety of industries, including 854411 Winding wire, 854420 Coaxial cable, and 853710 Boards, panels, consoles, desks, cabinets and other bases for electric control or the distribution of electricity. The versatility of this copper wire makes it an essential component in the production of electrical and electronic devices, as well as in the construction of buildings, vehicles, and other infrastructure.
