Ore Daily PerspectiveGlencore now reports less cobalt than Congo lets it export
Glencore's reported cobalt fell to 3.5 kt in the third quarter. That pace is below its 2026 and 2027 export allocations. Glencore says its stockpiles in Congo cover its quotas in the near term.
The numbers
Glencore produced 13.7 kt of own-sourced cobalt in the first nine months, down 52% from 28.5 kt a year earlier. The third quarter gave 3.5 kt, down 20% from the second. That is down about 64% from 9.6 kt in the third quarter of 2025, by Ore Daily's calculation.
At the nine-month pace, Glencore would report about 18.3 kt this year. At the third-quarter pace, it is about 14 kt a year. Both sit below its 2026 export allocation of 22.8 kt, which includes 2025 carryover, and below the 18.8 kt allocated for 2027, by Ore Daily's calculation. In 2023 it produced 41.3 kt.


Why output fell faster than exports
Glencore says it is putting copper first in Congo and selling cobalt from stock. Its KCC and Mutanda mines hold enough inventory to meet their quotas in the near term, the company said in January. It gave no 2026 cobalt guidance, citing too much uncertainty.
Some cobalt never shows up as output. Glencore says cobalt in mixed ore is increasingly held in solution and not dried into hydroxide. That material is not counted as production and will be processed later as rules change.
Congo replaced its export ban with quotas in October 2025. The cap is 87 kt a year for 2026 and 2027, plus a 9.6 kt state strategic quota, Glencore says. Reuters puts the total at 96.6 kt. That is about 42% of the roughly 230 kt Congo mined in 2025, based on USGS estimates, by Ore Daily's calculation. Glencore's 18.8 kt is 22% of the 87 kt company quota, the company says.
What to watch
Prices have come off the highs. Cobalt hydroxide fell 31% in the third quarter, Benchmark Mineral Intelligence said on Sept. 30. Its analyst George Ingall linked the drop to rising supply from Congo. LME cobalt still averaged $54,301/t from January to September, IMF data show, 56% above the 2025 average.
Glencore reports full-year production in late January. That will show whether it books more of the cobalt held in solution. Congo's quotas run to at least the end of 2027, Glencore says.
