· JVASP-114916· CuSnS3

CuSnS3 is a ternary copper-tin sulfide compound belonging to the metal sulfide family, characterized by mixed-valence coordination chemistry. This material is primarily investigated in research contexts for semiconductor and photovoltaic applications, where its tunable band gap and earth-abundant constituent elements offer potential advantages over conventional cadmium- or lead-based alternatives; industrial adoption remains limited, but the material class shows promise for thin-film solar cells, photoelectrochemical devices, and potentially low-cost optoelectronic components where material cost and toxicity constraints drive material selection.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
