On April 9, 2026, the Japanese Cabinet officially approved the latest amendment to the Waste Disposal and Public Cleansing Act (commonly known as the "Waste Cleansing Act"). The core of the amendment is to upgrade metal recycling operations from a notification system to a permit system, and to impose a new obligation requiring confirmation from the Minister of the Environment for scrap metal exports.

Global Aluminum Market Review – April: Divergent Domestic & Overseas Trends and Marked Spot Structure Disparities The global aluminum market in April featured a core pattern of strength overseas and weakness domestically with diverging trends. The main Shanghai aluminum contract retreated from highs amid fluctuations, while LME aluminum maintained firm momentum supported by low inventories and geopolitical factors, with both markets seeing mild corrections toward month-end. Market drivers this month centered on macro policies, geopolitical conflicts, supply-demand fundamentals and inventory structures, with movements of key indicators further highlighting supply-demand imbalances between domestic and overseas aluminum markets. I. April Aluminum Price Review: Linked Movements with Distinct Strength Differentials Shanghai aluminum and LME aluminum shared similar price rhythms in April, both fluctuating higher initially before retreating. However, notable gaps emerged in upward momentum and correction ranges, with overseas aluminum prices significantly outperforming domestic counterparts. The average Shanghai-LME aluminum ratio dropped from 7.36 in March to 7.03 in April, reflecting stronger overseas aluminum pricing relative to Shanghai aluminum. The main Shanghai aluminum contract trended upward early in the month before softening overall, declining from elevated levels through range-bound trading. It opened lower at RMB 24,715 per ton at the start of the month and consolidated. Driven by escalating Middle East geopolitical tensions and rising LME aluminum prices, it surged to a monthly peak of RMB 25,675 per ton in mid-April. In late April, amid continuous domestic inventory accumulation, weaker-than-expected downstream demand, and risk-averse capital outflows ahead of the May Day holiday, prices corrected steadily. Closing at RMB 24,430 per ton on April 30, the contract recorded a monthly trading range of nearly RMB 1,360 per ton. LME March aluminum traded firmly with mild late-month declines. Opening at USD 3,459 per ton, it climbed to a monthly high of USD 3,672 per ton in mid-April, underpinned by overseas supply disruptions from geopolitical frictions and sustained inventory destocking. Prices edged down later due to fluctuating US-Iran negotiations, hawkish macro sentiment and profit-taking at high levels, settling at USD 3,476 per ton at month-end with a slight monthly loss. Overall, LME aluminum vastly outperformed domestic Shanghai aluminum. In terms of price drivers, geopolitics served as a shared upward catalyst for global aluminum prices, with production cuts and supply disruptions in the Middle East continuously boosting market risk aversion. Price divergence stemmed from dual disparities in macro policies and fundamentals: elevated domestic inventories and sluggish demand consistently capped aluminum price rebounds, while tight overseas inventories and strained spot supplies provided robust support for LME aluminum. II. Key Inventory Indicators: Divergent Inventory Movements and Contrasting Supply-Demand Landscapes As a core gauge of aluminum market supply and demand, domestic and overseas inventory trends diverged sharply in April, directly shaping the relative strength of regional aluminum prices. Domestic aluminum inventories kept rising and stood at a multi-year seasonal high. Social inventories maintained an upward trend throughout April, hitting 1.465 million tons in mid-month, the highest seasonal level in five years. A clear imbalance emerged between rigid supply release and lackluster downstream demand during the traditional peak "Silver April" period, leading to persistent spot market loosening. SHFE warehouse stocks expanded from 420,000 tons at the start of the month to 450,000 tons at month-end. Elevated warehouse stock levels further confirmed ample domestic spot supply, weighing continuously on aluminum prices. Overseas LME aluminum inventories declined steadily to a 20-year low. Total LME aluminum inventories fell from 410,000 tons to 370,000 tons in April, extending months of destocking to historic lows. Noticeable structural divergence persisted in inventory composition: Russian aluminum accounted for approximately 92% of total LME stocks in March, resulting in low market-circulating inventories and increasingly tight physical spot supply, which acted as the fundamental pillar for strong LME aluminum prices. In summary, April’s global aluminum market was governed by contrasting core dynamics: low overseas inventories, geopolitical disruptions and hawkish Federal Reserve policies on the overseas front, versus high domestic inventories, weak real demand and stable growth expectations domestically. This drove pronounced market divergence. Affected by intertwined internal and external factors, the main Shanghai aluminum contract corrected downwards from highs, while LME aluminum remained in a firm trading range, backed by historically low inventories, a tight spot balance and geopolitical risk premiums.

According to customs data, China imported 6,835 tonnes of lithium hydroxide in March 2026, up 66% month-on-month and double year-on-year. Of this, 2,927 tonnes came from Indonesia, accounting for about 48% of total imports, while approximately another 40% came from Australia and South Korea. During the same period, China exported 3,143 tonnes of lithium hydroxide, up 20% month-on-month but down 26% year-on-year. In terms of exports, 2,059 tonnes went to South Korea and 278 tonnes to Japan. Since 2025, the combined effect of diverging domestic and overseas demand and continued overseas supply of lithium salts has caused excess lithium hydroxide to flow one‑directionally into the Chinese market. From the fourth quarter of 2025, domestic imports of lithium hydroxide remained at persistently high levels, while exports continued to weaken. Entering the first quarter of 2026, total imports exceeded 16,000 tonnes, while total exports were less than 8,000 tonnes, resulting in net imports of more than 8,000 tonnes — a complete reversal of the trade pattern characterised by "shrinking exports and surging imports". In terms of major import sources, Japan, South Korea, Australia and Indonesia accounted for a significant share. The key reason is that both domestic demand and prices are more favourable than overseas markets: In the third quarter of 2025, driven by expectations of subsidy policy reduction in 2026 and bullish sentiment on raw material prices, demand for ternary cathode materials remained strong in the fourth quarter. While overseas lithium hydroxide production lines maintained relatively stable output, downstream demand fell short of expectations, leading to rising inventory pressure among overseas holders – who had a strong incentive to destock towards the end of the year. Price increases for lithium hydroxide overseas lagged behind those in China, creating a profitable import arbitrage window. Coupled with the anticipated launch of lithium hydroxide futures in 2026, the number of trading participants involved in lithium hydroxide imports increased significantly. Given the long negotiation cycles and relatively stable supply channels with overseas suppliers, lithium hydroxide from Japan, South Korea and Australia has continued to flow into China. However, it is worth noting that although the continuous increase in import volumes has made lithium hydroxide more readily available for trading in China from Q4 2025 to Q1 2026, the quality of the lithium hydroxide flowing into the country is uneven due to the relatively customized production requirements of ternary cathode materials. As a result, there is a certain lag before it actually reaches material manufacturers. Looking ahead, as long‑term orders are steadily delivered, import volumes are expected to remain relatively high, while the potential for export growth is likely to remain limited.
