2853.90.10.00/Phosphor Copper Alloy CuP8/China

Phosphor Copper Alloy CuP8 from China

Phosphor copper alloy CuP8 contains approximately 8% phosphorus by weight combined with copper, exceeding the 15% threshold when formulated for high-phosphorus variants used in non-ferrous metallurgy. It is classified under HTS 2853.90.10.00 as a copper phosphide (phosphor copper) due to its chemical composition as a phosphide compound per Chapter 28 notes, specifically meeting the criteria for heading 2853 which includes copper phosphide with over 15% phosphorus. This master alloy is supplied in ingot or shot form for deoxidizing and alloying applications.

Import Tips

• Verify phosphorus content via certified lab analysis to confirm >15% threshold; provide material safety data sheets (MSDS) for phosphide hazards

• Ensure declaration as chemically defined inorganic compound under Chapter 28, avoiding misclassification as simple copper alloy
