About copper; foil, backed with paper, paperboard, plastics or similar backing material, of a thickness (excluding any backing) not exceeding 0.15mm, of refined copper

HS code 741021 covers the classification of copper foil, a thin and flexible material with a wide range of industrial applications. Copper foil is an essential component in various electronic devices, printed circuit boards, and packaging solutions. Its importance in the global economy stems from its unique properties, such as high electrical and thermal conductivity, corrosion resistance, and malleability, making it a versatile material for numerous industries.

Production process

The production of copper foil typically involves a process known as electroplating. In this method, a thin layer of copper is deposited onto a substrate, such as a stainless steel or aluminum sheet, using an electric current. The copper foil is then peeled off the substrate, resulting in a thin, flexible material. Depending on the desired thickness and quality, the copper foil may undergo additional processing steps, such as annealing or rolling, to achieve the required specifications.

Production inputs

The main inputs required for the production of copper foil include refined copper, which serves as the primary raw material, as well as electricity and specialized equipment like electroplating tanks and rolling mills. Additionally, the production process may require various chemicals, such as sulfuric acid or copper sulfate, to facilitate the electroplating and other finishing operations.

Production outputs

The primary output of HS code 741021 is copper foil, which is then used as a key component in the manufacturing of 854411 Winding wire for electrical machinery and equipment, 854420 Coaxial cable and other coaxial electric conductors, and 854442 Electric conductors, for a voltage not exceeding 1,000 V, fitted with connectors. Copper foil is also widely used in the production of 854411 Printed circuits and various packaging materials.
