[SMM Silicon-Based PV Morning Meeting Summary] Polysilicon: N-type recharging polysilicon was quoted at 34-36.1 yuan/kg. Polysilicon prices were relatively stable overall, with extremely limited order signing in the market. Some crystal pulling plants showed low-price purchase willingness, but top-tier manufacturers still held the floor above 35 yuan. With cost setting imminent, manufacturers had a strong wait-and-see sentiment. Wafer: Market 18X wafer prices were 0.9-0.93 yuan/piece, 210RN wafer prices were 1.00-1.03 yuan/piece, and 210N wafer prices were 1.2-1.23 yuan/piece. Recently, a top-tier enterprise completed bulk transactions of 210R wafers at 1.02 yuan/piece. Currently, except for 210N, the other two sizes had already accepted the previous round of price increases, and subsequent trends would depend on downstream cell price movements.

【SMM Copper Cathode Rod News Flash】In April, as copper prices continued to rebound, downstream purchasing sentiment was dampened. New orders for copper cathode rod enterprises slowed down somewhat, but influenced by the low operating rates of secondary rod producers, orders for copper cathode rod enterprises remained resilient. The operating rate decreased 3.86 percentage points MoM to 71.2%.

[Macro Policy and Tug-of-War Between Sellers and Buyers: Aluminum Prices Move Sideways] The risk of supply disruptions to aluminum outside China has not yet subsided, and there remains a supply gap in ex-China aluminum, with the strong LME market transmitting to China and providing support for aluminum prices. However, the continuation of inventory buildup exceeding expectations in China will weigh on domestic aluminum prices. Meanwhile, tightened invoicing regulations may lead to structural tightness in spot cargo, and the weakening spot market further limits the upside room for domestic aluminum prices. Close attention should be paid to the potential turning point in China's social inventory, which could drive a rebound and rise in aluminum prices.

[SMM Cast Aluminum Alloy Morning Comment: Tightening Supply Sources Combined with Pullback in Imports, Tight Aluminum Scrap Circulation Underpins Prices] Aluminum alloy 2607 in the night session exhibited an overall trend of "retreat after rapid rise, hover at lows." From the intraday perspective...

Driven by recovering risk appetite and China's peak demand season, copper prices both in China and abroad bottomed out since late March. However, as SHFE copper returned to the 100,000 level, the tug-of-war between longs and shorts increased, and futures prices shifted to range-bound consolidation. After the Labour Day holiday, copper prices quickly resumed their upward momentum. Today, prices opened higher with a gap and continued to rise, with SHFE copper just one step away from the record high set at the end of January, while LME copper hit a new closing high. What is fueling such strong confidence behind this rally? Deepening Ore-Side Vulnerability Intensifies Supply Disruption Concerns Since the suspension of First Quantum's Cobre Panama copper mine at the end of 2023, spot TC for copper concentrates in China has been caught in an endless downward spiral. Falling from around $80/dmt at the end of 2023, it largely dropped to single-digit levels and moved sideways in 2024. Entering 2025, it further plunged into negative territory, mainly due to successive production disruptions at world-class copper mines including Ivanhoe Mines' Kakula, Codelco's El Teniente, and Freeport's Grasberg mine in Indonesia. Entering 2026, global major copper ore supply growth remained limited, and the ore tightness showed no improvement. The latest data showed that spot TC for copper concentrates in China had fallen below -$90/dmt. With long-term contract TC at zero and spot TC declines accelerating, domestic smelters' production profits mainly relied on surging sulphuric acid prices and firm by-product prices of gold, silver, and other metals to compensate. It was reported that current sulphuric acid revenue could already cover smelters' procurement costs for copper concentrates and part of the processing costs, enabling domestic smelters to maintain relatively high operating rates, and the ore tightness had not yet notably transmitted to the smelting side. It is worth noting that sulphuric acid is not only a by-product of pyrometallurgy but also a core production material for SX-EW copper. For every 1 mt of copper produced, 5–6 mt of sulphuric acid is consumed. Sulphuric acid costs account for 40%–50% of total SX-EW copper production costs, and SX-EW copper production accounts for approximately 20% of global mine copper production. Since the beginning of this year, sulphuric acid prices surged sharply due to multiple factors, and ex-China sulphuric acid supply was periodically disrupted, raising concerns that copper supply in some countries could be affected. Focusing on the reasons behind the sulphuric acid price surge: on one hand, since the escalation of the Middle East conflict on February 28, shipping through the Strait of Hormuz has been broadly restricted and has recently faced a dual blockade by Iran and the US. Sulphur exports from the Middle East have been impacted, with the DRC and Zambia being the most concentrated SX-EW copper producing regions that are highly dependent on sulphur imports from the Middle East. As sulphur supply has been constrained, sulphuric acid prices have naturally risen in tandem, not only raising local SX-EW copper production costs but also potentially triggering further production cuts if the Strait of Hormuz blockade continues and sulphur disruption risks escalate. On the other hand, to prioritise domestic spring ploughing phosphate fertiliser production and support new energy industry expansion, China has imposed a phased ban on sulphuric acid exports according to industry sources. Chile has a relatively high dependence on Chinese sulphuric acid, with SX-EW copper accounting for around 20% of its output, and the market is also concerned that Chile's SX-EW copper production may be affected. In addition, against the backdrop of an already fragile copper ore supply, frequent news shocks from outside China recently have undoubtedly intensified market concerns. Last week, market rumours suggested that the full restart of Indonesia's Grasberg copper-gold mine, which declared force majeure in September last year, had been delayed by one year, driving SHFE copper sharply higher in the afternoon of 8 May. However, according to the latest update from Freeport-McMoRan, the company still expects Indonesia's Grasberg copper-gold mine to fully resume production by the end of 2027, reaffirming the plan outlined last month and refuting reports that production resumptions could be delayed to 2028. Furthermore, yesterday Peru declared an emergency energy decree due to a natural gas pipeline explosion. Peru's copper production reached 2.63 million mt in metal content last year, ranking third globally. Copper mining and smelting are relatively sensitive to power stability, and the market is concerned that Peru's energy strain may disrupt local copper supply. Overall, China's copper cathode production remains relatively stable, but some major global miners lowered their full-year production guidance in Q1, the ore tightness persists, sulphuric acid supply — a core raw material for ex-China SX-EW copper — is constrained, and there are multiple supply disruption themes on the copper supply side, which can easily boost copper prices once the macro front stabilises. Global Copper Visible Inventory Divergence: China Destocking Provides Support Last year, driven by the US government's threat to impose additional tariffs on imported copper, global copper continued to flow into the US, causing COMEX copper inventories to accumulate continuously while copper inventories in non-US regions remained low, providing sustained support for copper prices. In February this year, the US Supreme Court struck down most of the tariff measures introduced by the Trump administration in 2025. The Trump administration subsequently turned to Section 122 of the Trade Act of 1974 to push new global tariff policies. On 7 May, the US Court of International Trade issued a ruling stating that the legal basis for imposing a 10% global import tariff was invalid. The tug-of-war between US courts and the Trump administration over tariffs has continued recently, but the market has certain expectations that the US may subsequently impose additional tariffs on imported copper. Under such expectations, the price spread between COMEX copper and LME copper has shown a slight strengthening trend recently, meaning copper in LME warehouses still has the potential to flow to the US. Specifically, COMEX copper inventories have continued to rebound since mid-April, rising from around 590,000 mt to the latest 620,000 mt, again hitting a multi-year high. Correspondingly, LME copper inventories pulled back from around 400,000 mt in mid-April, declining to 397,700 mt on 6 May. They have rebounded with fluctuations recently, but overall inventories have not exceeded the over-12-year high set in mid-April. SHFE copper inventories fell for the eighth consecutive week, currently dropping to 181,300 mt, the lowest since the beginning of the year. Data source: Webstock Inc. Overall, on the macro front, there are currently disagreements in US-Iran negotiations, but both sides continue the ceasefire with no recent signs of escalation in conflict. Energy prices pulled back from late April levels, inflation concerns eased somewhat, the US dollar index was in the doldrums, and combined with the AI boom lifting global stock markets, market risk appetite was moderate, providing a fertile ground for copper prices to strengthen. Focusing on copper's own fundamentals, inventories outside China remained elevated, but significant prior destocking of China inventories provided support. The ore tightness was difficult to reverse, and supply-side narratives were abundant, meaning copper prices may still hold up well. However, it is worth noting that the Middle East situation remains the biggest macro variable, and the policy path following the Fed Chairman's power transition also deserves close attention.

On May 12, 2026, iron ore futures were in the doldrums, with the most-traded contract I2609 closing at 812.5 yuan/mt, down 0.98% from the previous trading session. Port spot prices fell 5-7 yuan from the previous trading day. Traders were relatively active in quoting; steel mills restocked on an as-needed basis; overall spot transactions were limited. Affected by fluctuations in the coking coal market, ferrous metals futures prices declined across the board today. Fundamentals side, according to SMM survey results, the hot metal impact from blast furnace maintenance was 1.4075 million mt this week, up 25,000 mt WoW. The hot metal impact from blast furnace maintenance next week is expected to be 1.4045 million mt, down 3,000 mt WoW. Iron ore demand weakened slightly this week, but no clear trend has formed yet overall. Even though steel mills were generally reluctant to purchase high-priced ore, robust end-use demand supported steel mill blast furnace operating rates and rigid demand for iron ore. Therefore, iron ore prices are expected to remain stable on the downside in the short term, and prices are expected to fluctuate at highs.

As of May 12, the operating rate of 50 major construction steel EAF steel mills nationwide was 41.9%, up 1.32% WoW; capacity utilization rate was 43.0%, up 0.99% WoW; daily average construction steel production was 95,700 mt, up 2,200 mt WoW.

According to the latest statistics from the GACC, total iron ore imports in April 2026 amounted to 103.854 million tonnes, representing a decrease of 889,000 tonnes from the previous month, a month-on-month decline of 0.8%. From January to April, cumulative imports of iron ore and its concentrates reached 418.587 million tonnes, marking an 8.0% increase year-on-year. In April, steel mills generally exhibited subdued purchasing activity due to the limited cost-effectiveness of imported iron ore. Concurrently, rising premiums and shipping costs further compressed import margins, diminishing the purchasing intentions of some importers. Nonetheless, strong downstream demand resulted in high utilisation rates of blast furnaces within steel mills, sustaining elevated levels of pig iron production and maintaining robust iron ore demand. Additionally, ongoing geopolitical tensions in the Middle East led to adjustments in some iron ore shipping routes originally designated for export to that region, with China increasingly serving as a transit and receiving hub, which contributed to an overall increase in China's iron ore imports. Consequently, despite a slight decrease in April, import levels remained broadly stable under the influence of various factors. Looking ahead to May, the gradual recovery of port facilities in major importing countries from weather-related disruptions is expected to facilitate a significant increase in shipments from key iron ore-producing nations. Meanwhile, steel mills are anticipated to sustain high operating rates driven by profit margins, indicating that demand for iron ore imports is likely to remain strong. Furthermore, overseas mines that commenced production earlier are still in the ramp-up phase, which will support continued shipment growth. The Simandou iron ore mine is projected to reach its first shipping peak in May, with the majority of shipments destined for China. However, the Labour Day holiday in May, which reduces working days and could impact customs clearance efficiency and data collection, may result in a marginal increase in China's iron ore imports compared to April.

[Inventory Buildup and Macro Tailwinds Offset Each Other, Aluminum Prices Trade in a Range] The risk of supply disruptions to aluminum outside China has not yet subsided, and the ex-China aluminum ingot supply-demand gap will continue to provide support for aluminum prices. Meanwhile, the continuation of higher-than-expected inventory buildup in China will weigh on domestic aluminum prices. At the same time, tightened invoicing regulations may lead to structural tightness in spot cargo, and the weakening spot market will further limit upside room for domestic aluminum prices. Close attention should be paid to the potential emergence of a turning point in China's social inventory, which could drive a rebound and rise in aluminum prices.
