HS Code for Unwrought brass

Unwrought brass is classified under HS code 7403.21, which specifically identifies copper-zinc base alloys. In the context of the Harmonized System, brass is defined as an alloy of copper and zinc, with or without other elements. When other elements are present, zinc must predominate by weight over each of those other elements. The term "unwrought" refers to primary forms such as ingots, billets, slabs, and wire-bars that are intended for further processing. These forms are usually produced by casting or sintering. This classification is part of heading 7403, which encompasses refined copper and copper alloys in unwrought forms. Accurate classification is dependent on the chemical analysis of the alloy to ensure it meets the specific definition of brass provided in the Chapter 74 legal notes. If the alloy contains more than 10% by weight of nickel, for example, it might be classified as cupro-nickel rather than brass, highlighting the importance of precise metallurgical data. This code is used by foundries and manufacturers who import raw brass to create semi-finished products like pipes, fittings, or decorative hardware.

Products Included

• Brass ingots
• Brass billets and slabs
• Brass cakes and wire-bars
• Unwrought copper-zinc alloys
• Cast brass blocks for remelting

Common Misclassification

Unwrought brass is frequently confused with refined copper (7403.11 to 7403.19) or other copper alloys like bronze (7403.22). Another common error is classifying brass scrap under this code; scrap should be under 7404.00. Finally, if the brass has been worked into bars or rods, it must be classified under 7407.21.

FAQ

What is the HS code for unwrought brass?

Unwrought brass, specifically copper-zinc base alloys, is classified under HS code 7403.21.

What defines "unwrought" for brass?

Unwrought forms are primary shapes like ingots, billets, or slabs produced by casting or sintering, which have not been rolled, extruded, or forged.
