SMM June 3 news: According to customs data, China's cadmium telluride (CdTe) exports showed a continuous upward trend over the past three months. Following exports of 48 mt in February, exports rose to 64 mt in March and further climbed to 80 mt in April. Market participants noted that the increase in exports was well reflected in the continuous rise of domestic tellurium prices. Market participants stated that the core reason for tellurium price increases remained on the supply side, where China maintained a highly monopolistic position with global supply being extremely concentrated. Demand side, multi-sector resonance drove steady demand growth, particularly as summer approached and the peak season for thermoelectric cooling modules arrived, boosting end-user purchasing demand for tellurium. This year, large overseas end-users such as First Solar continued to expand CdTe thin-film module capacity, providing strong long-term support for global tellurium raw material demand. Additionally, AI data center construction would also highly likely trigger thermoelectric cooling demand. As AI computing chip power consumption continued to climb, bismuth telluride thermoelectric cooling modules became a key thermal management solution, inevitably driving structural growth in tellurium demand. In the short term, China's export controls showed no signs of easing. Although CdTe exports were on an upward trend, the likelihood of further significant increases was relatively small. Meanwhile, downstream CdTe PV and AI thermoelectric demand continued to accelerate in release, and the tight balance in tellurium supply-demand dynamics would most likely persist, with prices expected to stay high or even continue to rise. Risk factors to watch include: whether the recovery rate of tellurium as a by-product of copper mine improves, and progress in ex-China alternative capacity (such as tellurium recycling technology).

[SMM Analysis] SS declined, combined with persistently weak transactions during the off-season, and stainless steel inventory stopped its decline, stabilized, and slightly accumulated.

[SMM Analysis] SS Decline and Weak Off-Season Trading Keep Stainless Steel Inventory Basically Stable with Slight Buildup SMM, June 25: This week, stainless steel social inventory ended its previous destocking trend, and under off-season conditions, overall inventory stabilized and edged up slightly. Total inventory in the two core markets of Wuxi and Foshan rose slightly, from 932,000 mt on June 18, 2026, to 932,800 mt on June 25, up 0.06% WoW. The inventory shifted from continuous destocking to slight buildup, with off-season inventory pressure becoming marginally apparent. This week, the stainless steel market was fully in the traditional consumption off-season, with end-user rigid demand support continuing to weaken. During the week, metals futures weakened across the board, coupled with news-related disturbances from Indonesia. SS futures drifted lower, bearish sentiment in the market intensified, downstream end-users became more wait-and-see, overall purchasing willingness was insufficient, and spot market trading remained weak. This week, news of maintenance and production cuts at steel mills continued to simmer, with some mills reducing shipments, leading to a marginal decline in market supply. Meanwhile, traders, amid pessimistic expectations, showed low willingness to actively purchase, and generally adopted strategies of selling at lower margins and reducing inventory to accelerate the turnover of goods on hand. This largely offset the inventory buildup pressure from weak off-season demand, keeping overall social inventory basically stable with only a slight increase. Overall, the core factors behind the shift from destocking to slight inventory buildup this week were weak end-user rigid demand during the off-season and weakening futures dampening market sentiment. Meanwhile, supply contraction from steel mill maintenance and traders' proactive destocking provided critical support to prevent a pronounced inventory buildup. At this stage, the market's off-season characteristics are increasingly evident...

A Guangdong Tungsten Enterprise's Long-Term Contract Procurement Price Remained Flat in Second Half of June

[Wolfram Snapshot] SMM, June 25: A Guangdong tungsten enterprise announced its long-term contract purchase quotations for the second half of June as follows: wolframite concentrates (55% grade) at 518,000 yuan/standard tonne (65% WO3 basis), scheelite concentrates (55% grade) at 517,000 yuan/standard tonne (65% WO3 basis). The long-term contract prices for ore were flat MoM from the first half of June. APT (national standard, zero grade) was executed at 780,000 yuan/mt, flat compared with the long-term contract price in the first half of June.

Today, tungsten concentrate transactions were scarce, and the short-term market was in the doldrums.

[Tungsten Express] SMM June 24: The tungsten concentrates market saw sparse transactions today. Downstream smelters mainly purchased as needed, while mines faced difficulty with shipments. Some spot orders were concluded at negotiated prices centered below online quotes and long-term contract prices, and the market was mainly in the doldrums in the short term. This week, attention will focus on auction results for medium- and low-grade tungsten concentrates from mines in Yunnan, Shaanxi, and Hunan, as well as the long-term contract prices of an enterprise in Guangdong.
