Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pure chemical without luminescent doping
Undoped cadmium sulfide is a general sulfide salt under Chapter 28.
If for non-luminescent synthetic inorganic coloring use
Shifts if primary function is pigmentation over luminescence.
If pre-incorporated into photosensitive semiconductor wafers
Finished photosensitive components move to Chapter 85.

Import Tips & Compliance
• Comply with hazardous material regulations (cadmium toxicity) including proper UN labeling and DOT shipping papers
• Submit XRF analysis confirming CdS composition and luminescent grade to avoid Chapter 28 classification
