Cobalt Price Per Tonne — The Scale Buyers Actually Use
One tonne of cobalt, scaled from today's per-gram rate of ₹3.56, comes to ₹3,563,080.00 on September 17, 2026. Battery-materials refiners and superalloy producers both transact at this scale routinely, negotiating directly against LME and Fastmarkets benchmark pricing rather than working up from a gram figure the way a retail buyer might.

Why This Figure Swings More Than Most Industrial Metals
Cobalt's supply concentration in the Democratic Republic of Congo, combined with the country's export quota system, means a single policy decision or a shift in one major producer's output can move the tonne-scale price sharply — a genuinely different dynamic than a metal with production spread across a dozen independent countries. That's part of why cobalt has earned a reputation for volatility that metals like copper or zinc simply don't carry to the same degree.
Metal, sulfate, or something else entirely
Not every tonne of "cobalt" priced in the market is the same product. Cobalt sulfate — the battery-grade chemical form most EV cathode manufacturers actually buy — is priced separately from refined cobalt metal, since it's a different processing step with its own separate market. This page tracks the metal reference rate; buyers sourcing sulfate specifically should expect a different, though related, number.
| Form | Typical Buyer |
|---|---|
| Refined cobalt metal | Superalloy and industrial producers |
| Cobalt sulfate | EV battery cathode manufacturers |

Reading This Figure Against the Broader Supply Picture
Because so much of global cobalt supply rides on decisions made in copper and nickel mining — cobalt is overwhelmingly a byproduct of both — a rise in demand for cobalt alone doesn't necessarily pull much new supply online quickly. New cobalt output depends more on copper and nickel mining economics than on cobalt's own price, a structural quirk that makes this tonne-scale figure move differently than a primary-mined metal's price would.
The comparison table and 10-day history above track that movement in context. For a longer view, the site's own cobalt price history page holds real recorded data by year and month.
Cobalt Price Per Tonne — FAQs
Scaled from today's per-gram figure of ₹3.56, one tonne of cobalt works out to ₹3,563,080.00 on September 17, 2026. This is a reference conversion — real cobalt deals are typically negotiated in tonnes directly against LME or Fastmarkets benchmark pricing, not converted up from a gram figure.
Battery-materials refiners producing cobalt sulfate for lithium-ion cathode manufacturers are the largest tonne-scale buyers, alongside superalloy producers supplying aerospace and jet-engine manufacturers — a smaller but genuinely distinct buyer group from the battery side.
Because supply is unusually concentrated and now shaped by government export quotas out of the Democratic Republic of Congo, small changes in policy or industrial output there can move the global tonne-scale price sharply — a genuinely different dynamic than a metal with dozens of independent producing regions.
Not exactly — cobalt pricing references both London Metal Exchange quotes and Fastmarkets benchmark assessments, and the two can differ, which is why this site's own cobalt benchmark comparison page exists as a dedicated explainer.
No — cobalt sulfate, the battery-grade chemical form most EV cathode manufacturers actually buy, is priced differently from refined cobalt metal, reflecting the extra processing step and the fact that buyers need different quantities of contained cobalt depending on the chemical form.
