China exported 40,668 tonnes of refined zinc in August, its second-highest monthly total in almost 20 years, as tight supply on the London Metal Exchange made overseas sales profitable. Most of it went straight into LME warehouses in Asia.
At a glance
- China was a net zinc exporter by 4,388 tonnes in the first eight months of 2026.
- LME warehouses in Hong Kong, Singapore and Kaohsiung have received about 73,000 tonnes since mid-August.
- Refined zinc output outside China fell 3.4% in the first half of 2026.
Background
The London Metal Exchange (LME) is the world's main market for industrial metals. A squeeze happens when little metal is available for immediate delivery, so cash zinc trades at a premium to zinc for delivery in three months. When LME prices rise above Chinese prices, traders can buy zinc in China, ship it out and deliver it to LME warehouses for a profit.
What happened
China exported 40,668 tonnes of refined zinc in August, the second-highest monthly total in almost 20 years, Reuters columnist Andy Home reported. The country was a net exporter by 4,388 tonnes in the first eight months of the year and is on course to be a net annual exporter for the first time since 2022.
Much of the metal went straight into the exchange's own stores. LME warehouses in Hong Kong have taken in 35,000 tonnes since mid-August, Singapore 21,250 tonnes and Taiwan's Kaohsiung port 16,725 tonnes. Together, the three accounted for 80% of China's August shipments. Metal in LME-registered warehouses can be delivered against exchange contracts, which is what makes the trade work.
Why it happened
Zinc outside China is scarce. Refined output in the rest of the world fell 3.4% in the first half of 2026, and some Western smelters are struggling. Nyrstar chief executive Guido Janssen said its Budel smelter "is losing money every year, and the conditions for next year look particularly difficult."
That shortage pushed LME prices above Chinese prices and opened an arbitrage window. Chinese smelters, sitting on a surplus, have been selling into it.
What it means
The Chinese shipments are easing the squeeze. LME-registered stocks have risen from 88,000 tonnes in mid-August to 126,975 tonnes. Cash zinc still trades at a $60-a-tonne premium to the three-month price, showing the market remains tight.
For India, where Hindustan Zinc made a record 212,000 tonnes of refined zinc last quarter, LME prices set the benchmark for domestic zinc. More Chinese metal flowing into LME stores could gradually cool those prices.
Our read
Outlook: bearish. Rising Chinese exports and LME stocks are easing the squeeze that lifted zinc prices. The market is still tight, so any fall may be gradual.
What to watch
- China's September zinc export data to see if the arbitrage window stays open.
- LME zinc stocks and the cash-to-three-month premium.
- Further closures or cuts at Western zinc smelters.

Detailed analysis
Timeline
- 2026-10-06: Reuters reports China exported 40,668 tonnes of refined zinc in August.
Supply Drivers
Refined zinc output outside China fell 3.4% in the first half of 2026.
Inventory Drivers
LME zinc stocks rose to 126,975 tonnes from 88,000 tonnes in mid-August.
Refinery Output
Chinese smelters are producing a surplus they can now sell abroad.
What could lift prices
- Western zinc output is falling, and smelters such as Nyrstar's Budel are losing money.
- Cash zinc still trades at a premium, showing tight nearby supply.
What could weigh on prices
- Chinese exports are refilling LME warehouses and easing the squeeze.
- China is on course to be a net zinc exporter for the year.
Country impact
| Country | Impact | Reason |
|---|---|---|
| China | High | Its smelters are exporting surplus zinc at the fastest pace in years. |
| India | Low | Domestic zinc prices follow the LME benchmark. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Metal Smelting | Negative | Western smelters face pressure as Chinese exports ease prices. |
| Galvanizing | Positive | More available zinc could ease costs for galvanisers. |
Who gains, who loses
- Chinese zinc smelters: They can sell surplus metal into the higher-priced LME market.
- Western zinc smelters: Rising Chinese supply could undercut prices as their output falls.
Other ways this could play out
- If the LME premium narrows further, Chinese exports could slow and the arbitrage close.
- If more Western smelters cut output, the squeeze could tighten again.
Price risks
- A further drop in Western output could keep LME zinc tight despite Chinese exports.
- A pickup in Chinese domestic demand would reduce metal available for export.
Historical comparison
- 2022: China was last a net annual exporter of refined zinc in 2022.
