Naval Brass Slab from Mexico
Naval Brass Slab is an unwrought copper-zinc alloy slab containing about 1% tin and lead, used for propeller shafting and marine hardware. The tin content is below 3%, so it remains a brass (copper-zinc base alloy) under Chapter 74, and as an unwrought product it falls under tariff item 7403.29.00 for other copper alloys.

Import Tips
• Confirm the slab's dimensions and shape meet the definition of unwrought products, as bars or profiles have separate classifications
• Keep documentation of the alloy composition, especially tin and lead content, to justify the brass classification
• Check if the slab requires any special permits for marine use
