HS HEADING 7403

Copper; refined and copper alloys, unwrought

In plain English

This category covers copper and its alloys in raw, unworked forms. The items are split into refined copper products, such as cathodes, wire-bars, and billets, which are further divided by specific type or grouped together if they do not fit those specific categories. The remaining sections address various copper alloys, including brass based on copper and zinc, bronze based on copper and tin, and other unspecified copper alloys that are not master alloys.

Chapter 74 classification notes

Chapter 74 dominated by major Chilean / Zambian / DRC supply chains. Recycled copper trade subject to Basel Convention waste-trade controls.

Frequent misclassification in this chapter

Copper alloys (brass, bronze) — depending on minor alloy content.

Classification certainty

The 6-digit level shown here is the internationally harmonised layer. Duty rates attach to national 8-10 digit tariff lines, which differ by country — use the duty calculator for lane estimates. For binding certainty, request a ruling from the destination customs authority.
