Beryllium Copper Thick Plate for Aerospace Components
A high-strength beryllium copper plate measuring 10mm thick, used in manufacturing precision aerospace structural components. Classified under HTS 7409.90.10.30 due to its beryllium copper alloy composition and thickness exceeding 5mm, falling within Chapter 74 for copper plates and sheets over 0.15mm. Meets subheading definitions for copper alloys excluding specific brasses, bronzes, or nickel silvers.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If thickness under 5mm but over 0.15mm
Same beryllium copper alloy but thinner gauge moves to subheading for plates/sheets <5mm.
If of copper-nickel-zinc (nickel silver) base alloy
Alloy composition changes to nickel silvers (5%+ nickel) shifts to specific copper-nickel-zinc heading.
If made of aluminum rather than copper alloy
Material switches from copper Chapter 74 to aluminum Chapter 76 plates/sheets.

Import Tips & Compliance
• Provide mill test certificates verifying beryllium copper alloy composition per subheading note (a)-(d) exclusions
• Measure and document exact thickness to confirm >5mm classification; thinner sheets shift to 7409.90.10.50
• Comply with REACH and TSCA regulations for beryllium content due to toxicity risks
