Guangdong: Yesterday, the refined zinc purchase sentiment in the Guangdong region was 1.66, and the sales sentiment was 2.48. Yesterday, traders' offer prices remained relatively high, but downstream demand has already entered the off-season. Combined with the lack of significant fluctuations in zinc prices, overall market demand was rather ordinary. However, the ongoing impact of invoices in the current market persisted, and spot premiums continued to rise.

Tianjin: Yesterday, the refined zinc purchase sentiment in the Tianjin region was 1.82, and the shipments sentiment was 2.42. Yesterday, zinc prices mainly maintained a fluctuating trend. With the rainy season limiting end-user construction activities, galvanizing orders weakened, and downstream purchase sentiment was low. The Tianjin market had relatively ample supplies, but traders' shipment premiums remained slightly stable, and overall market transactions were still moderate.

Ningbo: Yesterday morning, futures zinc prices fluctuated. Traders' shipment offer prices in the market were flat compared to the previous day. Yesterday, spot premiums remained stable. Some downstream factories had already made purchases earlier, and yesterday mostly adopted a wait-and-see approach. Overall zinc ingot shipments were sluggish.

Zinc price forecast: Overnight, LME zinc posted a bullish candlestick, with the upper Bollinger Bands forming resistance.

The US dollar index softened, LME zinc rebounded from lows, and the center shifted slightly higher. Overnight, SHFE zinc posted a bullish candlestick, with the 5-day moving average providing support below. On the fundamentals side, the tightness in zinc concentrates continued to support zinc prices. Combined with the boost from LME trends, the SHFE zinc center shifted higher during the night session, maintaining an overall fluctuating trend at highs.

Australia Reviews Anti-Dumping Duties on Galvanized Steel from India, Malaysia, Vietnam Amid Zinc Concerns
On September 9, 2026, Australia initiated its second sunset review of anti-dumping measures on galvanized steel sheet from India, Malaysia and Vietnam, and separately launched a sunset review of countervailing measures on imports from India. The review covers July 2025-June 2026, with the final report expected by February 11, 2027. As galvanized steel is the largest end-use sector for zinc, the measures directly affect export costs and competitiveness, potentially impacting Australia’s domestic zinc demand and supply chain. Maintaining the duties would provide some protection for domestic steel and coating capacity, while termination could increase low-priced imports and affect regional zinc consumption. The final outcome remains subject to the authorities’ determination.
