[SMM Aluminum Express News] Aluminum Corporation of China (Chalco) will invest approximately US$1 billion to build a 1.2 Mtpa alumina refinery in Guinea, strengthening upstream bauxite-to-alumina integration amid tightening global aluminum supply chains. The project includes supporting port infrastructure, while the Guinean government retains the option to acquire up to a 35% equity stake in the development.

This week, ferrous metals continued to pull back, with coking coal and coke seeing the most notable correction. In the first half of the week, the Ministry of Industry and Information Technology issued a notice on the implementation measures for capacity replacement in the steel industry, proposing that the capacity replacement ratio for ironmaking and steelmaking should be no less than 1.5:1. The further tightening of capacity replacement requirements had a longer-term impact. Meanwhile, macro markets outside China experienced significant fluctuations, and market expectations for ex-China "interest rate hikes" strengthened. In the second half of the week, data on the five major steel products were released, showing production increased somewhat while inventory continued to decline. Spot market side, traders began to show some flexibility on prices, the spot-futures price spread for hot-rolled coil continued to narrow, some spot-futures arbitrage traders mainly cut losses with shipments, and end-users continued to restock on an as-needed basis...

In Guinea, in the capital Conakry, Chalco Hong Kong—the project investment entity of Chalco, a publicly listed firm under Chinalco Group—signed an agreement related to the alumina project with the Guinean government. The local time in Guinea was May 21. The Chalco Guinea alumina project is another major international project invested and constructed by Chinalco Group in Guinea, following the Simandou iron ore project. Leveraging Guinea's high-quality resources, the project plans to invest approximately $1 billion to build a production line with an annual output of 1.2 million mt of alumina.

SMM News, May 6: According to SMM data, the average all-in tax-included cost of the domestic primary aluminum industry in April 2026 rose by 1.5% month-on-month and fell by 0.6% year-on-year, mainly due to a mild increase in prices of raw and auxiliary materials during the period. In April, the supply gap of primary aluminum overseas pushed up LME aluminum prices. However, high domestic inventory put strong downward pressure on aluminum price upside. The monthly average price of SMM A00 spot aluminum (March 26 - April 25) edged up only 1.0% month-on-month. The profit margin of primary aluminum narrowed slightly by RMB 12 per ton to RMB 8,303 per ton, with the average profit surging 125.1% year-on-year. Calculated based on the monthly average price, 100% of the operational primary aluminum capacity in the domestic market remained profitable in April. Breakdown of Cost Components Alumina price dipped intra-month but monthly average climbed month-on-month SMM data showed that the monthly average SMM alumina index stood at RMB 2,736 per ton in the statistical period of March 26 to April 25, up 1.9% month-on-month. The overall operational alumina capacity stayed stable during the month, and prices bottomed out and rebounded. Driven by market rumors over the bauxite quota policy in Guinea, bullish market sentiment picked up moderately. Nevertheless, the relatively high price at the start of the month lifted the overall monthly average. Entering May, with newly commissioned capacity ramping up steadily, alumina output is expected to increase. Meanwhile, continuous inflows of imported alumina into the domestic market will further ease spot alumina supply. Given the pending clarification of Guinea’s bauxite policy, supply tightening may trigger a minor price rebound. Alumina raw material costs are expected to remain in a consolidating trend in April. Rising costs drive up prices of auxiliary materials Geopolitical conflicts in the Middle East pushed up international crude oil prices in April. Higher cost levels kept petroleum coke prices on an upward track, underpinning higher prebaked anode prices. Aluminum fluoride prices also moved higher in April amid rising raw material costs. Auxiliary material prices will maintain an upward trend in May, driving a further rise in the auxiliary material cost of primary aluminum and lifting the overall cost center slightly. Power prices stabilize, hydropower costs expected to drop entering wet season Power prices remained generally steady in April. As the market gradually transitions from the normal water period to the wet season starting in May, hydropower tariffs in some regions are projected to edge down, leading to a mild decline in the power cost of primary aluminum production. Overall, the weighted average all-in tax-included cost of the domestic primary aluminum industry edged higher in April 2026. The primary aluminum cost is expected to keep rising moderately month-on-month in May, with the average level projected at around RMB 16,200 - 16,600 per ton.

SMM News, April 27: On April 24, 2026, market rumors emerged that Guinea would cap its bauxite export volume at 150 million tons, with the relevant policy to be officially released on April 25. The news drove a sharp rise in alumina during the overnight session that day. The main alumina contract 2609 hit a high of 2,899 yuan per ton and closed at 2,894 yuan per ton, up 2.76% from the previous settlement price. As of April 25, 2026, no updated official policy documents had been released on relevant government websites in Guinea. Per market rumors, Guinea’s bauxite exports will be restricted to 150 million tons. Should the final policy be implemented as rumored, based on Guinea’s general bauxite trade flow ratios and historical shipment volumes, SMM estimates that domestic bauxite imports from Guinea will drop to approximately 132 million tons in 2026. Customs data for 2025 showed domestic imports of Guinea bauxite stood at around 149 million tons, Australian bauxite imports at roughly 37.42 million tons, and non-mainstream source bauxite imports at about 14.26 million tons. If Guinea bauxite imports fall to 132 million tons in 2026, Australian bauxite imports remain largely stable, and non-mainstream bauxite imports edge down to around 12.5 million tons, the total domestic bauxite import volume is projected to decline to roughly 182 million tons. SMM forecasts domestic bauxite output to reach 79 million tons in 2026 (including volumes supplied for non-metallurgical alumina production), putting the total domestic bauxite supply at approximately 261 million tons for the year. SMM estimates domestic metallurgical alumina output at 87.22 million tons in 2026, sufficient to support a annually aluminum production capacity of 45.3 million tons. The alumina market will shift to a net import status. Factoring in bauxite demand for non-metallurgical alumina segments, overall bauxite total demand is expected to hit around 262 million tons. On the whole, the bauxite market fundamentals are set to shift into a tight balance in 2026. Amid raw material inventory buildup demand from newly commissioned alumina capacity, the bauxite market is theoretically poised to face mild tight supply conditions. However, actual market performance is expected to be looser than modelled calculations, for the following key reasons: Electrolytic aluminum production cuts in the Middle East have exacerbated overseas alumina surplus, while global bauxite supply contraction has lifted price expectations. Rising domestic bauxite prices will push up local alumina production costs, further enhancing the cost competitiveness of overseas alumina. Higher alumina imports will replace part of bauxite imports, easing domestic bauxite supply tightness. Elevated inventory levels will ease market tightness. In 2025, high price incentives drove a substantial increase in bauxite supply, resulting in a notable supply surplus and sharp inventory accumulation.Data from SMM showed domestic port bauxite inventories stood at 21.32 million tons and bonded ore inventories at alumina refineries at about 57.06 million tons by early 2026, with combined inventories reaching 78.38 million tons. Ample inventory buffers will keep actual market conditions looser than theoretical projections. In summary, if Guinea finalizes its policy to cap total bauxite exports at 150 million tons with no major fluctuations in ocean freight rates, bauxite prices are expected to trend a little bit higher. Nevertheless, substantial overseas alumina surplus and increased substitutable alumina imports will cap upside potential for bauxite prices. Barring unforeseen black swan events, neither bauxite nor alumina prices are likely to replicate the strong rally seen from late 2024 to early 2025. In the short term, both buyers and sellers in the bauxite market are adopting a wait-and-see stance, pending official updates on Guinea’s new policy. Market sentiment remains cautious, and prices are projected to move in a volatile range ahead of clear policy guidance.
