C26000 Cartridge Brass Sheet
C26000 cartridge brass sheet is a copper-zinc alloy plate with 30% zinc content, thickness 0.25 mm, and width 400 mm, used for precision stamping in ammunition casings and hardware. It falls under HTS 7409.90.90.60 as a copper alloy plate/sheet/strip exceeding 0.15 mm thick but less than 5 mm, with width under 500 mm. The brass composition meets the subheading note definition for copper-zinc base alloys where zinc predominates over other elements.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If width 500 mm or more
Wider sheets of copper-zinc alloys fall under 7409.21 for plates/sheets/strips ≥500 mm wide, changing the subheading based on dimension.
If thickness 5 mm or more
Thicker plates ≥5 mm are classified in 7409.40 regardless of width, as thickness threshold determines the structural subheading.
If in coils or rolls
Coiled strip form is classified under Chapter 74 heading 7407 for copper alloy bars/rods/profiles in coils, not flat plates/sheets.

Import Tips & Compliance
• Provide mill test certificates confirming alloy composition (e.g
• 70% Cu, 30% Zn) to verify copper-zinc base alloy status per chapter subheading notes
• Measure and document exact thickness (>0.15mm, <5mm) and width (<500mm) on commercial invoice to avoid reclassification to wider or thicker subheadings
