Zinc prices in China's Tianjin hub held near a multi-year high on September 7 as Shanghai futures rose and inventory fell, but downstream factories mostly stayed on the sidelines, calling transactions poor.
At a glance
- Tianjin's benchmark #0 zinc ingot traded at 26,780-27,220 yuan a tonne on September 7, up roughly 7% from the 24,980-25,300 yuan range seen in early August.
- The most-traded SHFE zinc contract for October delivery (2610) closed at 27,095 yuan a tonne, up 90 yuan or 0.33% on the day, after touching an intraday high of 27,245 yuan.
- SMM's national zinc ingot inventory tracker showed 222,100 tonnes across seven monitored regions, down 28,900 tonnes from August 31 and down 10,700 tonnes from just four days earlier, on September 3.
- Despite the price strength, SMM's Tianjin market report measured purchasing sentiment at just 1.61 against a selling sentiment of 2.44, and described overall trading as "relatively weak."
What happened
Zinc prices in Tianjin, one of China's largest physical zinc trading hubs, stayed near multi-year highs on September 7, with the benchmark #0 zinc ingot changing hands at 26,780 to 27,220 yuan a tonne, according to Shanghai Metals Market (SMM). That is roughly 7% above the 24,980-25,300 yuan range the same grade traded at in early August. The most-traded Shanghai Futures Exchange (SHFE) zinc contract for October delivery closed the day at 27,095 yuan a tonne, up 90 yuan, after touching an intraday high of 27,245 yuan. SMM's national zinc ingot inventory tracker, covering seven monitored regions, stood at 222,100 tonnes, down 28,900 tonnes from August 31 -- a decline SMM's futures desk said was lending support to prices alongside firmer London Metal Exchange (LME) zinc. Even so, SMM's Tianjin market report described buyer sentiment as weak, with most downstream factories waiting for better prices and overall trading activity "relatively weak."
The details
Tianjin's zinc market on September 7 captured a genuine tension: prices near multi-year highs, and almost nobody in a hurry to pay them. SMM's #0 zinc ingot traded at 26,780 to 27,220 yuan a tonne, with the premium Zijin brand fetching 26,980 to 27,360 yuan and the top-end Huxin brand quoted as high as 28,360 yuan. Behind those spot numbers, the most-traded SHFE zinc contract for October delivery closed at 27,095 yuan, up 90 yuan on the day after touching an intraday high of 27,245 yuan.
The reason prices are holding up is a genuine supply story, not just a trading mood. SMM's own futures commentary tied the day's higher close directly to "declining social inventory in China" alongside stronger LME prices. That inventory decline is specific and recent: SMM's seven-region zinc ingot tracker fell to 222,100 tonnes on September 7, down 28,900 tonnes from August 31 and 10,700 tonnes from just four days earlier. The same tightness shows up on a global scale. LME cash zinc has traded near $4,107 a tonne, its highest level since June 2022, as LME warehouse stocks collapsed roughly 64% from about 264,000 tonnes in December 2024 to near 95,000 tonnes -- their lowest since April 2023. The International Lead and Zinc Study Group has revised its own 2026 outlook to match, swinging from a forecast 271,000-tonne surplus to a 29,000-tonne deficit, a shift that followed real mine disruptions such as Boliden's Garpenberg operation cutting its 2026 milled-volume guidance from 3.7 million to 1.5 million tonnes after a seismic event damaged the mine.
But a tight paper and inventory picture is not the same as strong physical demand, and Tianjin's own numbers show the gap. SMM measured purchasing sentiment at just 1.61 against a selling sentiment of 2.44 -- traders eager to move metal, buyers in no rush to take it. The market's own pricing structure reflects that imbalance: #0 zinc ingot traded at a 20-140 yuan discount to the SHFE October contract, and the whole Tianjin market priced about 50 yuan below Shanghai. That is a market where sellers are competing on price to find buyers even while the benchmark futures contract sits near a four-year high -- exactly what SMM meant by describing "inquiries were limited today, traders held shipment premiums steady, and overall market trading was relatively weak," while downstream factories stuck to buying only enough zinc to cover immediate, rigid production needs rather than restocking into the rally.
That tension points toward the more interesting question for where prices go next: some market participants have told Fastmarkets that China is beginning to ramp up zinc exports, a shift that could relieve the same domestic inventory tightness now supporting Tianjin's prices. If that materialises at scale, the combination of easing local stockpiles and more Chinese metal reaching the global market could take some of the edge off both the SHFE benchmark and the LME price strength it has been tracking -- a genuine two-sided risk for a market that, for now, is being held up by supply rather than demand.
Why it matters
Even though this is a story about a Chinese domestic trading hub, it reaches Indian buyers and producers directly. India imported about $1.04 billion of zinc against $785.7 million in exports in 2025, making it a net importer that pays global benchmark-linked prices for a meaningful share of its supply. The same global tightness lifting Tianjin's prices -- LME cash zinc near a four-year high and LME warehouse stocks down 64% since December 2024 -- is the backdrop against which Indian producers price their own metal, so a sustained rally in China's domestic market is one more sign that the global cycle, not just local Indian supply and demand, is setting the floor under zinc prices this year.
Our read
Outlook: bullish. SHFE zinc closed higher on September 7 with national inventory falling and LME zinc near a four-year high amid a global supply deficit the ILZSG now projects for 2026, but weak purchasing sentiment and discounted physical premiums in Tianjin show the price strength is being driven more by tightening supply than by robust downstream demand -- a combination that supports the price without guaranteeing it holds if demand stays this soft.
What to watch
- Whether China's zinc exports continue rising, a trend some market participants have flagged to Fastmarkets that could ease the current domestic and LME inventory squeeze
- SMM's national zinc ingot inventory readings across its seven monitored Chinese regions, currently at 222,100 tonnes
- LME zinc warehouse stock levels, down roughly 64% from December 2024's approximately 264,000 tonnes
- Whether Tianjin's purchasing sentiment readings recover from September 7's weak 1.61 level as prices stabilize or pull back

Detailed analysis
Timeline
- 2026-08-05: Tianjin's #0 zinc ingot trades at 24,980-25,300 yuan a tonne, roughly 7% below where the same grade trades a month later.
- 2026-08-31: SMM's seven-region zinc ingot inventory tracker stands at roughly 251,000 tonnes, the baseline against which September 7's decline is measured.
- 2026-09-07: Tianjin's #0 zinc ingot trades at 26,780-27,220 yuan a tonne, the SHFE October zinc contract closes at 27,095 yuan (up 0.33% on the day), and SMM's inventory tracker falls to 222,100 tonnes.
Demand Drivers
In Tianjin, SMM measured purchasing sentiment at just 1.61 against a selling sentiment of 2.44, and reported downstream buyers largely restocking only to meet immediate, rigid production needs rather than building inventory at current price levels -- a classic sign that elevated prices are actively discouraging physical demand even as the futures market stays firm.
Supply Drivers
The International Lead and Zinc Study Group revised its 2026 global zinc balance from a forecast 271,000-tonne surplus to a 29,000-tonne deficit, a roughly 300,000-tonne swing driven partly by mine disruptions such as Boliden cutting 2026 milled-volume guidance at its Garpenberg mine from 3.7 million to 1.5 million tonnes after a seismic event. Some market participants have told Fastmarkets that China is beginning to ramp up zinc exports, which could ease the tightness over time.
Inventory Drivers
China's SMM-tracked national zinc ingot inventory fell to 222,100 tonnes across seven regions on September 7, down 28,900 tonnes from August 31 and 10,700 tonnes from September 3 alone -- a decline SMM's own futures desk cited as a direct support factor for SHFE zinc prices. Globally, LME zinc warehouse stocks have fallen roughly 64% from about 264,000 tonnes in December 2024 to near 95,000 tonnes, their lowest since April 2023.
What could lift prices
- LME cash zinc has traded near $4,107 a tonne, its highest level in more than four years, as LME warehouse stocks have fallen roughly 64% since December 2024 to their lowest since April 2023.
- China's own SMM-tracked zinc ingot inventory fell to 222,100 tonnes on September 7, down 28,900 tonnes in under a week, a decline SMM's futures desk linked directly to the day's higher SHFE close.
- The International Lead and Zinc Study Group now projects a 29,000-tonne global zinc deficit for 2026, reversing its earlier forecast of a 271,000-tonne surplus, after mine disruptions such as Boliden's Garpenberg seismic event cut output guidance.
What could weigh on prices
- SMM measured Tianjin's purchasing sentiment at just 1.61 against a selling sentiment of 2.44 on September 7, and described overall trading as "relatively weak," showing current prices are actively discouraging physical buying.
- Some market participants have told Fastmarkets that China is beginning to ramp up zinc exports, a shift that could ease the same domestic tightness now supporting prices.
- Tianjin's #0 zinc ingot traded at a 20-140 yuan discount to the SHFE October contract, with the whole Tianjin market pricing about 50 yuan below Shanghai -- signs that traders are competing on price to move physical metal even as the futures benchmark holds near its highs.
Country impact
| Country | Impact | Reason |
|---|---|---|
| China | High | The price, inventory and trading-sentiment dynamics described are all specific to China's domestic zinc market -- Tianjin, Shanghai and the SHFE benchmark contract. |
| India | Medium | India is a net importer of zinc and pays prices linked to the same global benchmarks that Tianjin's domestic market is tracking. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Mining | Positive | Elevated SHFE and Tianjin spot prices, supported by falling inventory and a tighter global 2026 balance, lift realisations for zinc miners and smelters even though physical trading volumes are thin. |
| Construction | Negative | Higher zinc prices raise input costs for galvanized steel used in construction and infrastructure, a cost downstream Chinese factories are already resisting by delaying purchases. |
Who gains, who loses
- Chinese zinc smelters and traders: Elevated SHFE and Tianjin spot prices, supported by falling national inventory, lift realisations even though physical trading volumes are thin.
- Zinc mine operators globally: A tighter 2026 global balance, revised by the International Lead and Zinc Study Group to a projected deficit, supports prices for producers regardless of any single day's Chinese trading volume.
- Chinese downstream galvanizing and die-casting factories: SMM measured weak purchasing sentiment in Tianjin as factories resist restocking at prices roughly 7% above early-August levels, raising their input costs whenever they do have to buy.
Other ways this could play out
- If Chinese zinc exports rise meaningfully from here, the combination of easing domestic inventory tightness and additional metal reaching the global market could soften both China's local premiums and the broader LME price strength that has supported them.
- If downstream demand stays as weak as September 7's sentiment readings suggest even as prices hold near multi-year highs, traders could be forced to cut premiums further to move inventory, a pattern already visible in Tianjin's discount to the SHFE contract.
Price risks
- A pickup in Chinese zinc exports could ease the domestic inventory tightness that is currently supporting Tianjin and SHFE prices.
- Purchasing sentiment in Tianjin has been running well below selling sentiment, and continued reluctance among downstream buyers to restock at current levels could eventually force traders to cut premiums further.
- The International Lead and Zinc Study Group's swing to a projected 2026 deficit rests partly on mine-disruption assumptions like Boliden's Garpenberg guidance cut, which could prove larger or smaller than currently estimated.
Historical comparison
- Early August 2026 vs. September 7, 2026: Tianjin's #0 zinc ingot has risen from a 24,980-25,300 yuan-a-tonne range to 26,780-27,220 yuan, a gain of roughly 7% in about a month, even as SMM has continued to describe downstream buying as poor or weak across that stretch.
