Copper-Phosphorus Master Alloy from China
A master alloy consisting primarily of copper with high phosphorus content (typically 10-15%) used in the non-ferrous metals industry to introduce phosphorus into brasses and bronzes. It falls under HTS 7405.00.60 as a master alloy of copper, classified as 'other' master alloys not specifically enumerated. This alloy aids in deoxidizing and improving fluidity during casting.

Import Tips
• Provide detailed chemical composition certificates to verify copper base and phosphorus content for proper classification under Chapter 74
• Ensure alloy meets master alloy criteria (high solute concentration >10%) to avoid reclassification as unwrought copper under 7403
