HS Code for Unwrought copper alloys

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.

Products Included

• Unwrought copper-nickel alloys (cupro-nickel)
• Unwrought copper-nickel-zinc alloys (nickel silver)
• Unwrought copper-beryllium alloys
• Copper alloy ingots and billets
• Copper alloy slabs and wire-bars

Common Misclassification

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.

FAQ

What is the HS code for unwrought copper alloys?

The HS code for unwrought copper alloys, other than brass, bronze, or master alloys, is 7403.29.

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.
