Copper, refined, unwrought, billets.
Classification of copper billets under HS 7403.13
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.

Codes often confused with 7403.13
Common mistake. 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%.
Top exporters and importers of HS 740313 (the code used for copper billets), 2025
In 2025, the largest exporter of HS 740313 (the code used for copper billets) in UN Comtrade data was Austria, with 52% of world exports; the largest importer in UN Comtrade data was France, with 30% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
