SMM April 30: SHFE lead fluctuated this week, with prices pulling back slightly near the weekend. On the raw material side, scrap battery procurement prices were largely stable overall, with only a few smelters in east China and north China making slight reductions early in the week. Current scrap battery retirement volumes remain at low levels, with tight supply for both recyclers and smelters. Smelter arrivals declined significantly WoW this week, with raw material inventory maintained at low levels of only 1-2 weeks. Combined with recyclers generally taking 2-6 days off for the Labour Day holiday, short-term supply circulation is expected to be further constrained. Looking ahead to next week, smelter procurement prices are expected to remain largely stable: upward adjustments are constrained by finished lead profit pressure, while downward adjustments are supported by low raw material inventory, leaving limited room for fluctuations in either direction.

SMM April 30 update: Lead prices fluctuated at highs before pulling back this week, with secondary refined lead generally trading at discounts. Early in the week, smelter maintenance increased and regional supply tightened, with quotes maintained at a discount of 80 yuan/mt to a premium of 50 yuan/mt. Downstream buyers saw weak rigid demand ahead of the holiday, and market trading was sluggish. From mid-week to the weekend, lead prices weakened. Raw material cost support narrowed quotes to a discount of 50 yuan/mt to a premium of 50 yuan/mt, as downstream enterprises gradually went on holiday and spot cargo transactions remained weak. Regional secondary lead supply contracted as smelters held prices firm on shipments. Combined with stable scrap battery procurement prices, smelting costs pulled back somewhat, and losses were slightly repaired. As of April 30, large enterprises posted losses of 109 yuan/mt, while small and medium-sized enterprises posted losses of 309 yuan/mt. Next week, scrap battery raw material inventory will remain tight, some smelters will cut production, and secondary lead supply will contract. Downstream consumption will remain weak, the weak supply-demand pattern on both sides will continue, and industry losses will be difficult to improve. Secondary refined lead is expected to maintain a discount of 50-0 yuan/mt.

In mid-April, CATL announced plans to invest 30 billion yuan to establish a wholly-owned subsidiary, Times Resources Group, registered in Xiamen and positioned as a professional investment, operation, and management platform in the new energy minerals sector. This major move is not only a key step for CATL in building a closed-loop entire industry chain of "ore — materials — battery — recycling," but will also inject strong momentum into the extraction and reuse of rare and precious metal resources, driving the battery recycling industry from standardized development toward a new phase of technological breakthroughs and scale expansion. The core mission of Times Resources Group is to integrate global critical minerals resources such as lithium, nickel, and cobalt, while expanding into high-quality rare and precious metal mining projects. From an industry perspective, lithium, nickel, and cobalt are core raw materials for power batteries, while rare and precious metals such as gold, silver, and platinum group metals are indispensable in electronic devices and catalysts. Through this 30 billion yuan capital deployment, CATL can both ensure that its primary lithium resources self-supply rate rises above 35% and keep lithium chemicals costs below 50,000 yuan/mt, while also establishing stable raw material connection channels for rare and precious metal regeneration after battery recycling through full industry chain control of mineral resources. More notably, CATL hired Chen Jinghe, founder of Zijin Mining, as a mining consultant, leveraging his extensive experience in mineral exploration and extraction to further optimize resource development processes. This means the upstream extraction segment will place greater emphasis on green and efficient technology applications, such as adopting efficient leaching technology for low-grade ore and comprehensive recovery processes for rare and precious metal associated ore, improving resource utilization rate from the source, laying the raw material foundation for rare and precious metal regeneration in subsequent battery recycling, and achieving synergy between "primary extraction + secondary recycling."

[SMM Vanadium Flash News] In April, Phase I of Jiaozuo Scandium-Vanadium New Materials Industrial Park was officially put into operation, with a total investment of 1.08 billion yuan. Relying on the by-product resources of titanium dioxide, the project has an annual production capacity of 2,500 tons of high-purity vanadium pentoxide + 20,000 cubic meters of vanadium electrolyte, directly supporting long-term energy storage orders. High-purity vanadium is entering the high-end alloy and vanadium battery markets, while the electrolyte has established the industrial chain of "titanium dioxide - vanadium electrolyte - energy storage", significantly increasing the added value of by-products..

[Silicon Metal Futures Center Shifted Higher with Increased Enterprise Shipments; Heavy Wait-and-See Sentiment in Polysilicon Market]: In the futures market, the most-traded contract trended stronger during the week, with the SI2609 contract center at 8700-8800 yuan/mt and the highest point touching above 8,900 yuan/mt. Driven by macro factors and news, futures rose, boosting silicon producers' shipment sentiment, and silicon enterprises' shipments to trading firms engaging in both spot and futures market increased. On the fundamentals side, silicon metal supply and demand were in tight balance in April, and the supply-demand structure is not expected to see major adjustments in May. Facing the pressure of increased supply during the rainy season in Sichuan and Yunnan from June to July, the market outlook leaned toward caution. On the cost side, raw material prices remained firm. With upside in silicon metal prices capped and downside supported by costs, the price fluctuation range was narrow.

As of April 30, the in-factory inventory of major primary lead delivery brands was 15,000 mt, a WoW increase of 2,000 mt. Recently, primary lead smelters saw both maintenance shutdowns and production resumptions coexisting, with regional output reductions in southwest and east China, and widening supply disparities across regions. In the consumer market, as downstream enterprises were about to take the Labour Day holiday, with some even starting their holidays early, pre-holiday stocking demand from downstream enterprises was limited. After a few battery enterprises went on holiday in the second half of the week, lead procurement volume shrank notably, and in-factory inventory at primary lead smelters edged up.
