According to SMM estimates, China's Grade 1 sodium pyroantimonate production in June 2026 will edge down slightly from the previous month, by approximately 4%, marking a second consecutive monthly decline following the modest dip seen in May.

According to SMM estimates, China's antimony ingot production (including antimony ingots, crude antimony on a converted basis, cathode antimony, etc.) in June 2026 edged up by approximately 2% month-on-month, showing a notably stable trend overall.

On the supply side of the antimony market, overseas ore continues to flow into the domestic market. The six-month-long price decline has prompted some traders to offload their inventories, though the downtrend has shown signs of easing recently. Major producers such as Yunnan Muli have gradually suspended production, yet some large manufacturers still have spot material available for sale, meaning supply is unlikely to tighten significantly in the near term.Market participants note that from a cost perspective, the mining cost of self-owned antimony ore at some major producers has risen to nearly 100,000 yuan per metal tonne. When adding the smelting and processing charges for antimony ingots, current spot prices are gradually approaching production costs.

Antimony prices fell sharply last week. On the supply side, some companies faced mid-year sales performance pressure in June, forcing them to offload inventory and adding to market supply. On the demand side, end-use demand remained weak — flame retardant operating rates declined, photovoltaic glass demand contracted, and polyester operating rates slid — all of which left buying interest among downstream consumers feeble.

Antimony prices maintained a steep downward trend this week. Entering the first half of June, overall market trading activity remained sluggish. End buyers stayed largely on the sidelines, purchasing only to meet immediate demand with a cautious stance. Nevertheless, certain enterprises faced mounting mid-year sales pressure and ramped up shipments. Recent selling prices from suppliers, particularly for antimony oxide, saw substantial price concessions. Suppliers prioritized moving inventory, which drove a rapid slump in market prices.

SMM, June 10 — A mining development company in Yunnan is set to carry out its 2026 concentrate sales plan, conducting a public inquiry-based sale of antimony concentrate containing 150 tonnes of antimony. The starting bid coefficient is 77%, with a deposit of RMB 100,000. The transaction location is Chuxiong City, Yunnan Province. Bidding commences at 15:00 on June 12, 2026.

According to SMM's assessment, China's antimony ingot production (including antimony ingots, crude antimony conversions, cathode antimony, etc.) in May 2026 declined significantly on a month-on-month basis, dropping approximately 27% compared to the previous month, showing a marked downward trend.

According to customs data, China's antimony oxide export volume in April 2026 stood at 379.385 metric tons, representing a modest month-on-month increase from the March export volume of 345.753 metric tons. Many market participants noted that given the current fundamental situation of antimony prices, the steady performance and minor fluctuations in antimony oxide export volumes over recent months are indeed quite consistent with market conditions.
