Phosphor Copper Master Alloy Ingot 10% P
Master alloy ingots composed primarily of copper with 10% phosphorus content by weight, used in non-ferrous metallurgy for deoxidizing and grain refining. Classified under HTS 7405.00.10.00 due to phosphorus content between 5-15% and its role as a copper master alloy per Chapter 74 notes. Supplied in standard 25kg ingots for foundry addition.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If phosphorus exceeds 15% by weight
Higher phosphorus content shifts to separate subheading within master alloys chapter.
If refined copper with trace phosphorus additives
Not a master alloy if used as refined copper rather than metallurgical addition agent.
If chemically prepared for specific industrial synthesis
Prepared additives/binders outside metallurgical master alloy definition fall in Chapter 38.

Import Tips & Compliance
• Require mill test certificates confirming exact P content (5-15%) to avoid reclassification; declare as master alloy not finished product; watch for anti-dumping duties on certain copper alloys from specific origins
