Product classification
HS code for Brass billets: 7403.21
Copper, copper-zinc base alloys (brass) unwrought.
Classification of brass billets under HS 7403.21
Brass billets are classified under HS code 7403.21 as unwrought copper-zinc base alloys. Chapter 74 covers copper and articles thereof. Heading 7403 is for refined copper and copper alloys, unwrought. According to the Chapter 74 Note 1(a), unwrought refers to products which have not been worked after casting, such as ingots, blocks, billets, and similar forms. Brass is defined in Note 1(b) as an alloy of copper and zinc, with or without other elements. Subheading 7403.21 is the specific code for these unwrought brass alloys. Billets are typically cylindrical or rectangular semi-finished castings intended for further processing like extrusion, rolling, or forging. The classification is strictly for the raw, unworked form of the alloy; once the billet is shaped into a rod, bar, or wire, the classification changes to a different heading within Chapter 74.

Codes often confused with 7403.21
Common mistake. Brass billets are frequently misclassified under HS code 7407.21, which covers brass bars and rods. The distinction lies in whether the product is unwrought (cast) or wrought (worked). Billets are cast forms (7403), while bars and rods are typically extruded or drawn (7407). Another common error is using 7404.00, which is for copper waste and scrap. While billets may be made from recycled material, they are finished unwrought products, not scrap.

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).
