C46400 naval brass slab is an unwrought copper-zinc-tin alloy with a maximum of 1% tin, maintaining brass classification. It falls under tariff item 7403.21.00 as copper-zinc base alloy because zinc predominates over tin (which is less than 3%), and the slab is unwrought.

Import Tips
• Confirm the tin content is below 3% to ensure classification as brass, not bronze
• Provide a certificate of analysis showing the alloy composition for CBSA
• Verify the slab is unwrought—if it has been machined or drilled, it may be classified elsewhere
