Cadmium is primarily recovered as a byproduct of zinc smelting, and its trade in unwrought, scrap, and powder forms is shaped by that upstream dependency rather than by dedicated mining. Its principal end uses — nickel-cadmium batteries, pigments, and electroplating — face increasing regulatory pressure in many markets due to cadmium's toxicity, which can affect import admissibility and downstream handling requirements. Importers should be aware that environmental and hazardous-materials regulations at the state and federal level may impose additional compliance obligations beyond standard customs entry.
