HS Code 7403.13 – Copper; refined, unwrought, billets
HS code 7403.13 is the 6-digit subheading for copper, refined, unwrought, billets. It is used for copper billets, refined copper ingots (billet form), continuous cast billets, oxygen-free copper billets and phosphorus deoxidized copper billets.
What HS 7403.13 covers
HS 740313 covers refined, unwrought copper in the form of billets. Billets are typically cylindrical or square-sectioned pieces of refined copper, produced by continuous casting or conventional casting. They serve as a crucial intermediate product for the extrusion and drawing of copper rods, bars, and tubes, which find extensive use in plumbing, HVAC systems, automotive components, and various industrial machinery. The trade in copper billets is driven by the manufacturing sectors that require these specific shapes for further processing. Importers are often fabricators and manufacturers in industrial economies, while exporters are major copper refiners and casters. The quality and consistency of billets are paramount for efficient downstream manufacturing processes, making them a vital part of the global copper supply chain.

Codes often confused with 7403.13
Common mistake. While also refined unwrought copper, billets (740313) are distinct from cathodes (740311) and wire-bars (740312) in their cross-sectional shape and primary end-use for extrusion.
Top exporters and importers of HS code 740313, 2025
In 2025, the largest exporter of HS code 740313 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).
