C26000 Cartridge Brass Ingot
C26000 cartridge brass is a copper-zinc base alloy containing approximately 30% zinc, cast into ingot form for further processing. It falls under HTS 7403.21.00.00 as unwrought brass meeting the definition of copper-zinc base alloys where zinc predominates over other elements. Commonly used for ammunition casings and architectural applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper content exceeds 96% with minimal zinc
Alloys with very high copper content are classified as refined copper rather than copper-zinc base alloys.
If classified as master alloy for remelting
Master alloys of heading 7405 are specifically for alloying other metals, distinguished from standard unwrought alloys.
If tin content 3% or more
Copper alloys with significant tin become copper-tin base alloys (bronzes) per subheading note (b).

Import Tips & Compliance
• Obtain mill test certificates verifying chemical composition meets copper-zinc base alloy definitions (zinc predominant, nickel <5%, tin <3%)
• Ensure proper documentation of alloy grade (e.g
• UNS C26000) to avoid misclassification as refined copper
• Check for anti-dumping duties on specific brass alloys from certain countries
