HS Code for Copper billets

7403.13 Copper; refined, unwrought, billets
Metals & Metal Products
View full HS code details

Copper billets are classified under HS code 740313, which specifically identifies refined copper in an unwrought state. According to the General Rules of Interpretation (GRI) and the Explanatory Notes to the Harmonized System, Chapter 74 covers copper and articles thereof. Heading 7403 is reserved for refined copper and copper alloys in unwrought forms, such as ingots, pigs, slabs, and billets. The classification 740313 is designated for billets of refined copper, which are typically produced by continuous casting or by rolling an ingot into a semi-finished cylindrical or rectangular shape intended for further processing into tubes, rods, or wires. To qualify for this code, the material must meet the purity standards for "refined copper" as defined in Note 1(a) to Chapter 74, requiring a minimum copper content of 99.85% by weight, or slightly less if specific elements like silver are present within defined limits. Because these are intermediate products that have not been further worked than by simple casting or hot-rolling into a shape for extrusion, they remain in the unwrought category.

Products Included

  • Refined copper cylindrical billets
  • Solid copper logs for extrusion
  • Unwrought refined copper rectangular billets
  • Continuous cast copper billets

Common Misclassification

Copper billets are frequently confused with copper bars and rods classified under HS code 7407. The distinction lies in the degree of processing; 740313 is for unwrought forms, whereas 7407 covers products that have been further worked (e.g., cold-drawn or rolled to final dimensions). Additionally, they may be confused with copper alloy billets (740321-740329) if the copper purity is below 99.85%.

FAQ

What is the HS code for copper billets?

The HS code for refined copper billets is 740313.

What is the difference between a billet and a cathode?

A cathode (740311) is a primary product of electrolytic refining, while a billet (740313) is a cast shape produced from melted cathodes or scrap, intended for extrusion or forging.
