Chapter 74: Copper and articles thereof

Plain-language overview

Use HS-6 740313 when importing or exporting refined copper billets. These are typically large, solid pieces of copper that have been processed to remove impurities, making them suitable for further manufacturing. For example, a shipment of 5,000 kg of copper billets for electrical wiring would fall under this code.

This HS-6 code specifically covers unwrought copper in the form of billets, which are often used in the production of various copper products. In contrast, HS-6 740311 refers to refined copper cathodes, which are flat and thin sheets used primarily in electrolysis and other processes.

Copper billets classified under HS-6 740313 are essential for industries that require high-quality copper for casting, extrusion, or forging. If you’re dealing with copper in other forms, like powders or scrap, you’ll need to look at different HS codes.

When shipping copper billets, ensure that your documentation clearly states the weight and purity level, as customs may require verification of the material's quality. Accurate classification helps avoid delays and potential penalties.
