Cadmium Phosphide from China
Cadmium phosphide serves as a II-V semiconductor material for infrared detectors and photovoltaics. This chemically defined phosphide of other metals falls under HTS 2853.90.50.00, distinct from organic or alloy forms. Its band gap properties suit optoelectronic applications.

Import Tips
• Handle as TSCA-listed toxic substance; include exposure limits and waste disposal plans
• For semiconductor wafers, confirm unworked form—processed discs go to 3818.00
• Export controls may apply under Wassenaar for dual-use optoelectronic materials
