No commercial production.
Nihonium has no commercial supply chain. It is a laboratory-made superheavy element whose significance is scientific rather than industrial: confirming the synthesis and decay of element 113 helped complete the seventh row of the periodic table and informs ongoing work on nuclear stability near the superheavy region.
In practice, nihonium exists only as single atoms created in accelerator facilities. RIKEN's superheavy-element program remains active as of the 2025 snapshot, but the work is focused on new-element and isotope research, not on any bulk production or market application.
