China exported 40,668 metric tonnes of refined zinc in August 2026, marking the country's second-highest monthly export volume in nearly two decades, according to data compiled by The Oregon Group from World Bureau of Metal Statistics and Chinese customs figures. This export surge represents a fundamental shift in the global zinc market, as China transitions from its traditional role as a major net importer to a net exporter. The magnitude of August's export activity becomes clear when compared to July volumes, with August exports exceeding the previous month by more than four times.
China's imports fell to approximately 2,300 metric tonnes in August, resulting in net exports of 38,300 metric tonnes for that month alone. Across the first eight months of 2026, China accumulated net exports of 4,388 metric tonnes, a reversal of its historical import position. The export wave has significantly impacted London Metal Exchange inventory levels.
LME registered zinc stocks rose from 88,000 metric tonnes at mid-August to 126,975 metric tonnes by early October as Chinese metal arrived in approved warehouses across Asia. Hong Kong received 35,000 metric tonnes of zinc from mid-August to early October, while Singapore accepted 21,250 metric tonnes and Kaohsiung in Taiwan received 16,725 metric tonnes. While official Chinese customs data for September has not yet been published, physical evidence suggests export shipments continued into the following month.
Shanghai Metals Market reported that the export window remained open during September as international zinc prices continued to exceed domestic Chinese market prices after adjusting for currency, freight and other costs. However, the market analyst expects exports to moderate as the arbitrage opportunity narrows. The export activity has provided immediate relief to the LME market squeeze, though not complete resolution.
LME three-month zinc prices peaked at a four-year high of approximately US$4,065 per metric tonne in early September, subsequently declining to approximately US$3,715 per metric tonne by early October. The cash premium over three-month metal contracted from US$215 per metric tonne in late August to approximately US$60 per metric tonne, indicating narrowing market tightness. Despite the inventory rebuilding, cash zinc continues to trade above three-month contracts in a market structure known as backwardation, signaling that buyers still pay premiums for immediately available metal.
This persistent premium indicates that the underlying supply constraints have not been fully resolved. The export surge reflects a divergence between Chinese and Western zinc markets. Weak construction activity has weighed on domestic Chinese demand for galvanized steel, while China's refined-zinc production increased by 5.9 percent during the first half of 2026.
By contrast, refined production outside China fell 3.4 percent over the same period. On the raw material side, global zinc mine production declined by 2.6 percent year-over-year in the first half of 2026, as major operations including Antamina in Peru and Red Dog in Alaska processed lower-grade ore. This supply constraint has intensified competition between smelters for concentrates, pushing spot treatment charges to reported negative US$113 per metric tonne in August.
These negative charges transfer value from smelters to miners and place severe pressure on smelter processing margins. European smelters face particularly acute challenges due to elevated electricity costs. Nyrstar launched a strategic review of its 315,000-metric-tonne-per-year Budel smelter in the Netherlands on September 24, citing Chinese overcapacity, competition for feedstock, historically low treatment charges and elevated European energy costs.
The facility continues to operate during the review process. The longer-term implications of this market development extend beyond near-term price movements. While Chinese zinc shipments have lowered prices and rebuilt LME exchange inventories in the short term, the underlying structural issues remain unresolved.
The current squeeze is rooted partly in falling mine supply and weakening smelter economics. Moving Chinese metal into LME warehouses addresses the shortage of deliverable zinc but does not repair Western processing capacity or increase the supply of concentrate. China is on course to become a net annual zinc exporter for the first time since 2022.
The strategic point highlighted by market analysts is straightforward yet concerning for Western supply security: the West is attempting to reduce its dependence on Chinese processing for critical minerals, yet the LME zinc market increasingly requires Chinese smelters to supply its metal of last resort.
