HS-4 · Heading
7405 — Copper; master alloys
Chapter 74: Copper and articles thereof
Plain-language overview
Use HS-4 7405 when importing copper master alloys, such as those used in electrical applications or metal fabrication. For instance, if you're bringing in a shipment of copper-aluminum master alloys, this is the correct code.
The distinction within this heading is straightforward, as it primarily covers master alloys of copper. If your product is a master alloy that includes copper as a primary component, it falls under HS-6 740500. However, if it’s a different type of alloy or a copper product without alloying elements, you’ll need to look at other headings.
When deciding between HS-4 7405 and other nearby headings, consider the composition of your alloy. If your product contains significant amounts of other metals alongside copper, it may not qualify under this specific heading and might require classification under a different HS code.
