Copper, refined, unwrought, billets.
Classification of refined copper billets under HS 7403.13
Refined copper billets are classified under HS code 7403.13. Billets are a specific form of unwrought refined copper, typically produced by continuous casting or by casting into molds. They are characterized by their solid cylindrical shape and are primarily used as the starting material for the extrusion of copper tubes, pipes, and rods. Under the Harmonized System, Chapter 74 Note 1(a) defines refined copper based on specific purity thresholds (minimum 99.85% copper or specific impurity limits). Heading 7403 covers unwrought forms, and 7403.13 is the specific subheading for billets. Because these items are cast and have not been subjected to further mechanical working like rolling or drawing, they remain in the unwrought category rather than being classified as semi-finished products.

Codes often confused with 7403.13
Common mistake. Refined copper billets are frequently misclassified under HS code 7407.10, which covers refined copper bars and rods. The distinction lies in the manufacturing process: 7403.13 is for "unwrought" (cast) billets, while 7407.10 is for products that have been "worked" (rolled, extruded, or drawn). If the cylindrical shape has been further processed to achieve precise dimensions or improved grain structure through mechanical means, it is no longer a billet. Another error is using 7403.19, which is a residual category for other unwrought shapes like slabs or cakes. Billets must be cylindrical to qualify for 7403.13. Lastly, if the billet is made of a copper alloy (e.g., brass), it must be classified under 7403.21-29.
Top exporters and importers of HS 740313 (the code used for refined copper billets), 2025
In 2025, the largest exporter of HS 740313 (the code used for refined 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.

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).
