Cadmium markets are trading in a relatively narrow range as the structural decline in by-product output from zinc smelters offsets steady but unspectacular demand. Asian benchmark prices for 99.99% cadmium ingot stood at approximately $3,876/tonne in China, $4,301/tonne in Japan, and $4,358/tonne in India as of late 2025, according to IMARC data, with modest upward drift through early 2026 driven by tighter zinc smelter operating rates.
The supply dynamic is the most distinctive feature of the cadmium market. Cadmium is not mined directly; over 90% of global output comes as a by-product of zinc smelting, primarily from sphalerite ores. This means cadmium supply is governed entirely by zinc production economics and environmental controls, not by cadmium price signals. On average, one tonne of zinc concentrate contains approximately 3 kg of cadmium, per International Cadmium Association (ICdA) data.
Global cadmium metal production has declined from approximately 23,000 tonnes in 2015 to around 18,500 tonnes by 2022, as major zinc smelters deliberately reduced cadmium recovery rates amid tightening environmental regulations. China produced approximately 9,500 tonnes of refined cadmium in 2025, with South Korea contributing 4,300 tonnes, making them the dominant producing countries. ICdA data shows total global production and consumption broadly flat at approximately 25,000 tonnes annually over two decades when recycling and different product forms are included.
Demand is anchored by two competing trends. Nickel-cadmium (Ni-Cd) battery demand continues its structural decline as lithium-ion batteries replace Ni-Cd in portable electronics and power tools. However, Ni-Cd remains entrenched in emergency backup, aviation, and rail applications where reliability and extreme temperature performance justify retention of the older chemistry. Cadmium telluride (CdTe) solar photovoltaic manufacturing, in contrast, provides growing demand. First Solar, the dominant CdTe module producer, has ramped capacity steadily, absorbing a meaningful share of global cadmium consumption.
The bull case for cadmium prices rests on the continued decline in zinc by-product recovery, particularly as Chinese and OECD environmental standards tighten, and steady CdTe solar demand. The bear case is that Ni-Cd replacement is accelerating as lithium-iron-phosphate (LFP) battery costs decline and reliability improves, eroding the largest traditional demand segment. The market appears to price these factors in rough balance.
Cadmium buyers are dealing with a market where supply is beyond the influence of cadmium pricing. Procurement strategy should focus on supply security rather than price timing: (1) Establish direct relationships with zinc smelters that recover cadmium, particularly in South Korea and China, to secure allocation during periods of reduced zinc output; (2) For Ni-Cd battery manufacturers, the declining production base means forward contracting is essential — spot availability can disappear when zinc smelters cut runs; (3) The CdTe solar sector should negotiate multi-year off-take agreements with producers, as the sector's growth trajectory will increasingly compete with battery demand for limited supply; (4) Monitor environmental regulation developments in China, where tightening emissions standards could further reduce cadmium recovery rates. Target procurement range: $3,800-4,500/tonne for standard-grade material; high-purity 5N/7N premium grades command significantly higher prices and require separate supplier qualification.
