Product classification
HS code for Unwrought copper alloys: 7403.29
Copper, copper alloys n.e.c. in heading no. 7403 (other than master alloys of heading no. 7405).
Classification of unwrought copper alloys under HS 7403.29
Unwrought copper alloys are classified under HS code 7403.29. Chapter 74 covers copper and articles thereof, and heading 7403 specifically addresses refined copper and unwrought copper alloys. Subheading 7403.29 serves as a residual category for copper alloys that do not fall under more specific descriptions such as copper-zinc alloys (brass) or copper-tin alloys (bronze). To be classified here, the copper content must predominate by weight over each of the other elements present. The term "unwrought" implies that the alloy is in a primary form, such as ingots, billets, slabs, or wire-bars, produced by casting or sintering. This classification is essential for distinguishing raw alloy materials from master alloys, which are used as additives, and from semi-manufactured copper products like plates or sheets.

Codes often confused with 7403.29
Common mistake. Unwrought copper alloys are often confused with HS code 7405.00, which covers master alloys of copper. Master alloys are compositions used to introduce alloying elements into other metals and are not intended for direct processing into finished goods. Another common error is using 7403.21 (copper-zinc alloys) or 7403.22 (copper-tin alloys) for alloys that do not meet the specific chemical requirements for brass or bronze. Finally, any material that has been rolled or extruded must be moved to headings 7407 through 7410.
Top exporters and importers of HS 740329 (the code used for unwrought copper alloys), 2025
In 2025, the largest exporter of HS 740329 (the code used for unwrought copper alloys) in UN Comtrade data was Thailand, with 13% of world exports; the largest importer in UN Comtrade data was China, with 72% 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).

Questions about unwrought copper alloys
What is the HS code for Unwrought copper alloys?
The HS code for Unwrought copper alloys is 740329 (Copper; copper alloys n.e.c. in heading no. 7403 (other than master alloys of heading no. 7405)). The HS code for unwrought copper alloys, other than brass, bronze, or master alloys, is 7403.29.
How do I classify Unwrought copper alloys for customs?
Unwrought copper alloys is classified under HS code 740329 — Copper; copper alloys n.e.c. in heading no. 7403 (other than master alloys of heading no. 7405). This is a 6-digit subheading level code.
Can copper scrap be classified under 7403.29?
No, copper waste and scrap are classified under HS code 7404.00, regardless of whether they are alloys or refined copper.
Which countries are the top exporters of unwrought copper alloys (HS 740329)?
In 2025, the top exporters of HS 740329 (the code used for unwrought copper alloys) in UN Comtrade data were Thailand ($143M, 13% of world exports), Germany ($115M) and Japan ($112M). World exports came to about $1.1B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of unwrought copper alloys (HS 740329)?
