China flipped to zinc net exporter in 2026 as domestic mine output fell and smelters ran for export margins; LME touched $3,608/t in June

Summary

China became a net exporter of refined Zinc in Q1 2026, shipping approximately 30,000 tonnes more than it imported over the three months, a sharp reversal from 209,767 tonnes of net imports in full-year 2025. The shift reflects a structural decline in Chinese zinc mine output, down approximately 7% year on year in Q1 2026 as legacy deposits in Hunan, Yunnan and Inner Mongolia experienced grade depletion, reducing the concentrate feed available to Chinese smelters and prompting them to export refined zinc where global prices offered margin. The International Lead and Zinc Study Group reported a 19,000-tonne global deficit in the first two months of 2026, against a 46,000-tonne surplus in the same period of 2025. LME zinc cash settled at $3,608.50 per tonne on June 23, near its year-to-date high. Korea Zinc commissioned a Tennessee facility in February 2026 to recycle electric arc furnace dust into approximately 30,000 tpa of zinc-equivalent product, using IRA Section 45X credits. CRU Group projects a full-year 2026 global deficit of 150,000-200,000 tonnes if Chinese smelter export behaviour and Western mine curtailments persist.

The split

The deficit camp (CRU, Fastmarkets) argues that China's mine-output decline is structural, not cyclical: the Hunan and Yunnan deposits that built China's zinc industry are past peak grade, and no major Chinese greenfield mine is in the development pipeline. The corollary is that Chinese smelters will increasingly compete for imported concentrate, tightening TC/RC terms for Western miners in the same pattern that copper saw in 2024-2025. The more cautious view (ILZSG, S&P Global) notes that Western mine curtailments from the 2023-2024 price downturn are partially reversible: Nyrstar's idled Budel smelter, Boliden's Kokkola, and Century mine's potential restart could add supply faster than the deficit models assume. The Korea Zinc Tennessee investment is the first major Western zinc recycling plant under the IRA framework, but EAF dust recovery is volume-constrained by the quantity of steel scrap processed, and 30,000 tpa does not move the global balance materially.

By the numbers

• ~30,000t, China's net zinc exports in Q1 2026 (first quarterly net-export position in years).
• 209,767t, China's net zinc imports in full-year 2025.
• 19,000t, ILZSG-estimated global refined zinc deficit in January-February 2026.
• 46,000t, global zinc surplus in January-February 2025.
• ~7%, year-on-year decline in Chinese zinc mine production in Q1 2026.
• $3,608.50/t, LME zinc cash price on June 23, 2026.
• 100,000t, Korea Zinc Tennessee annual EAF dust processing capacity (recovers ~30,000t zinc equivalent).
• 150,000-200,000t, CRU's projected full-year 2026 global zinc deficit.

Why it matters

Zinc is the fourth-most-used metal globally, primarily for galvanizing steel against corrosion. It lacks the direct battery-chain narrative of lithium or cobalt, but as a critical input to construction, automotive and infrastructure steel, a structural zinc deficit has broad industrial cost implications. China's shift from net importer to net exporter of refined zinc is a market-structure inversion that reverses the flow of refined metal from East-to-West and tightens European smelter feedstock access, a pattern now visible across multiple base metals (copper TC/RC collapse, nickel surplus-to-deficit swings). The Korea Zinc Tennessee plant establishes the template for urban mining of zinc from the domestic steel-recycling waste stream under IRA incentives, a model that could partially decouple Western zinc supply from Chinese mine output over a 5-10 year horizon. But the near-term balance is driven by Chinese mine depletion and smelter export behaviour, neither of which Western policy can directly influence.

What to watch

• Chinese zinc mine output in H2 2026: whether Q1's 7% decline is sustained or partially offset by new Chinese mine openings.
• ILZSG monthly deficit/surplus data: whether the Q1 deficit widens through the year or narrows as Western smelters add back idled capacity.
• TC/RC terms for H2 2026 zinc concentrate contracts: if Chinese smelters compete aggressively for imported concentrate, TC/RCs will compress further, mirroring copper's trajectory.
• Korea Zinc Tennessee scale-up: whether the EAF dust model expands to additional US sites as IRA credits make secondary zinc competitive.
• LME zinc inventory levels and forward curve: a sustained backwardation would confirm the market is pricing the deficit thesis.
