[Imported Zinc Concentrate Market] Overseas ore supply disruptions have persisted recently. Offers for imported ore remained scarce this week, with some heard quoted at around -$80 to -$90/dmt, but smelters held a strong wait-and-see sentiment, keeping overall trading activity sluggish during the week.

[Zinc concentrate TCs remain low, keep watching subsequent smelter operations]: From weekly data, the SMM Zn50 domestic weekly TC average fell by 150 yuan/mt Zn WoW to -200 yuan/mt Zn, and the SMM import zinc concentrate index fell by $0.56/dmt WoW to -$71.76/dmt..

Time flies as the midpoint of 2026 approaches. The zinc concentrate market has witnessed another extraordinary price cycle this year. As of June 12, domestic zinc concentrate treatment charges (TCs) plunged to -50 yuan per metric ton of zinc metal, marking the arrival of negative TCs. Meanwhile, TCs for imported zinc concentrate tumbled to -71.2 US dollars per dry metric ton, both hitting all-time record lows.

【Imported Zinc Concentrate Market】Offer volumes of imported zinc concentrate remained limited this week. Smelters prioritized purchasing domestic ore, resulting in sluggish trading sentiment for imported zinc concentrate overall.

[Domestic Zinc Concentrate TCs Reach Negative Territory, TCs Continue to Decline]: On a weekly basis, the average SMM Zn50 domestic weekly TCs fell by 100 yuan/mt Zn WoW to -50 yuan/mt Zn, and the SMM imported zinc concentrate index dropped by $0.45/dmt WoW to -$71.20/dmt..

As we near the midpoint of the year, zinc concentrate treatment charges (TCs) have repeatedly tumbled to historic lows. As of June 5, the average TC for domestic zinc concentrate fell to 50 yuan per metric ton of metal content, while the TC for imported zinc concentrate dropped to -70.75 US dollars per dry metric ton.

Lead concentrate TCs were lowered by 50 yuan/mt Pb overall this week. The average weekly TC for domestic Pb50 was reduced to 200 yuan/mt Pb, while some silver-lead ores rich in copper and zinc were still quoted with high TCs above -2,000 yuan/mt Pb due to reasons such as non-pricing or low pricing of contained metals. Overall, lead concentrates remained in tight supply. Due to low arrivals of imported ore, the average weekly TC for imported Pb60 was reduced to -145 $/dmt, and the mainstream quotation range for smelters was lowered to -160 to -130 $/dmt. A few smelters accepted quotations above -200 $/dmt for imported silver-lead ores with good richness due to by-product revenue needs and other reasons. Some smelters have not yet finalized their prices for this month. In terms of negotiations and expectations, lead concentrates exhibited a polarization trend: smelters paid less attention to low-richness ores, but were still willing to accept high-metal-richness silver-lead ores. Additionally, the decline in imported zinc ore, to some extent, fueled the tight supply sentiment for lead ore, making lead concentrate TCs more likely to fall than rise. Meanwhile, the silver coefficient in lead concentrates remained unchanged, mainly because silver prices stayed range-bound and the coefficient had already risen to a relatively high level, thus remaining largely stable overall.

[Imported zinc concentrates market] According to SMM, this week few ore traders made offers in the market, and prices continued to decline. Meanwhile, smelters still prioritized purchasing domestic zinc concentrates due to the low import-to-domestic price ratio, and trading activity in the imported ore market was generally subdued during the week.
