HS code for Brass ingots: 7403.21
Copper, copper-zinc base alloys (brass) unwrought.
Classification of brass ingots under HS 7403.21
Brass ingots are classified under HS code 740321. This code pertains to unwrought copper-zinc base alloys (brass). The term "unwrought" refers to primary forms that have been cast into shapes such as ingots, blocks, or billets but have not yet undergone further working like rolling, drawing, or forging. These are essentially raw materials for the manufacturing industry, intended to be remelted and cast into finished products or extruded into bars and profiles. The classification is found in Chapter 74, which covers copper and its alloys. Subheading 740321 is specific to brass, distinguishing it from refined copper and other copper alloys like bronze. To qualify for this code, the material must meet the chemical definition of brass provided in the Chapter 74 notes, where zinc is the predominant alloying element. The physical form must be a crude casting; if the ingot has been machined or further processed beyond simple de-burring or surface cleaning, it may no longer be considered unwrought.

Codes often confused with 7403.21
Common mistake. Brass ingots are sometimes misclassified as HS code 740400, which is for copper waste and scrap. While ingots can be made from scrap, once they are melted and cast into a uniform shape for trade, they become unwrought metal under 7403. Another error is using 740721, which is for brass bars and rods; the difference is that 7407 items are "wrought" (worked) products, usually produced by extrusion or drawing, whereas 7403 items are "unwrought" (cast).
Top exporters and importers of HS 740321 (the code used for brass ingots), 2025
In 2025, the largest exporter of HS 740321 (the code used for brass ingots) in UN Comtrade data was the Netherlands, with 12% of world exports; the largest importer in UN Comtrade data was China, with 65% 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).
