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.

According to customs data, China's aluminum foil (tariff codes 76071110, 76071120, 76071190, 76071900, 76072000) total exports in March 2026 reached 103,500 mt, up 10% MoM but down 13% YoY. The share of exports to the UAE plunged from 6.8% in January-February to 2.5% in March, with the Middle East trade chain nearly severed.

According to customs data, China's aluminum plate/sheet and strip (tariff codes 76061121, 76061129, 76061191, 76061199, 76061220, 76061230, 76061251, 76061259, 76061290, 76069100, 76069200) exports in March 2026 reached 278,200 mt, up 21% MoM and up 3% YoY.

【SMM Analysis】 Why Are Chinese Lead-Acid Battery Enterprises Taking More Holidays for the 2026 Labor Day? As the Labor Day holiday approaches at the end of April, SMM conducted a survey on holiday arrangements among lead-acid battery enterprises across 10 provinces in China.

Around April 23, 2026, import and export data for cobalt and lithium battery industry chain products in March were released. Data showed that March spodumene imports rebounded significantly from February, hitting a new record high of 837,400 mt in physical content. Lithium carbonate side, China imported 29,974 mt of lithium carbonate in March, up 13% MoM and up 65% YoY.......SMM compiled the import and export data for battery materials as follows: Upstream Lithium Concentrates Customs data showed that March spodumene imports rebounded significantly from February, hitting a new record high of 837,400 mt in physical content. By source country: African ore arrivals increased notably — Nigeria imports reached 125,100 mt, up 63% MoM; Zimbabwe shipments from earlier periods arrived at ports in the month totaling 112,600 mt, up 61% MoM; Canada broke the zero-import situation in January-February with 58,600 mt arriving in March; while Australian ore volumes declined MoM due to shipping schedule impacts. According to SMM's screening and analysis, total port arrivals this month were equivalent to 81,000 mt LCE. Lithium concentrates accounted for 72% of the month's imports, down slightly compared to the same period last year, mainly due to the notable increase in South African raw ore port arrivals recently. Notably, driven by prices and local beneficiation plant development, Nigerian ore volumes increased significantly, with not only raw ore volumes rising markedly but also concentrates share increasing notably YoY. Source: China Customs, compiled by SMM Spodumene concentrates (CIF China) spot pricing side, according to SMM spot prices, March spodumene concentrates (CIF China) spot prices showed a V-shaped trend, dropping to a low of $2,028/mt at month-end, then rebounding to $2,313/mt at month-end, with a monthly average of $2,081.4/mt. According to SMM, in March, spodumene and lepidolite profit trends diverged, with structural cost differences among lithium chemicals enterprises becoming evident. Available spodumene volumes were tight, ore traders held back from selling, and inventory continued to be drawn down. Enterprises purchasing spodumene externally suffered losses on spot margins throughout the month, with non-integrated enterprises facing greater difficulties in hedging and procurement. Entering April, spodumene concentrates (CIF China) spot prices also showed a pattern of initial decline followed by recovery. Recently, spodumene concentrates prices continued to probe higher. As of April 27, spodumene concentrates (CIF China) spot prices rose to $2,507/mt, up $194/mt from $2,313/mt at end-March, an increase of 8.39%. According to SMM's recent research, driven by market expectations of improving future demand, speculative sentiment in the lithium carbonate futures market remained strong, pushing futures prices up. Lithium ore merchants showed increased willingness to sell, with pricing-against-futures prices staying high. Looking ahead, lithium chemical plant operating rates stay high, with demand for lithium ore continuing to climb. Meanwhile, Zimbabwe has suspended spodumene exports for nearly two months, leading to persistently tight available lithium ore supply in the market. Overall, spodumene prices are expected to hold up well. Lithium Carbonate According to customs data, China imported 29,974 mt of lithium carbonate in March, up 13% MoM and up 65% YoY. By source, the top 3 were Chile (18,000 mt, 61%), Argentina (8,292 mt, 28%), and Indonesia (2,100 mt, 7%). From January to March, China's cumulative lithium carbonate imports reached 83,000 mt, up 65% YoY cumulatively. China exported 448 mt of lithium carbonate in March, down 25% MoM and up 104% YoY. From January to March, China's cumulative lithium carbonate exports totaled 1,516 mt, up 46% YoY cumulatively. According to SMM spot quotes, lithium carbonate showed a volatile trend of first declining then rising in March. As of March 31, the average spot price of battery-grade lithium carbonate was quoted at 163,000 yuan/mt, with a monthly average price of 156,700 yuan/mt. According to SMM analysis, spot lithium carbonate prices in China showed a significantly volatile upward trend in March, with the monthly average price up 5% MoM. Fundamentals-wise, supply side, production gradually recovered as maintenance ended, and lithium chemical plants showed increased willingness to sell spot orders at the relatively high level around 170,000 yuan/mt; demand side, downstream cathode material producers basically adopted a dip-buying strategy, with strong purchase willingness at price levels around 140,000 to 150,000 yuan/mt. As demand continued to improve, some enterprises engaged in large-scale restocking at low levels. In March, battery-grade spot lithium carbonate prices rose to 172,500 yuan/mt at the beginning of the month and pulled back to around 163,000 yuan/mt at month-end. Recently, battery-grade lithium carbonate spot quotes stayed high above 170,000 yuan. As of April 28, battery-grade lithium carbonate spot quotes were at 172,000-177,000 yuan/mt, with an average price of 174,500 yuan/mt. According to SMM, in today's spot lithium carbonate market, as lithium carbonate prices declined, downstream purchase enthusiasm picked up, with some buyers' target prices basically around 170,000 to 175,000 yuan/mt; upstream spot order quotes remained at high levels. Overall, market inquiries and transactions were relatively active. Looking ahead, the supply side presents mixed signals: Huayou in Zimbabwe announced the successful shipment of lithium sulfate over the weekend, which may ease some supply anxiety in the short term; however, disruptions from mine license renewals in Jiangxi persisted, Middle East geopolitical fluctuations pushed up diesel costs, and some Australian mines confirmed cost increases in their Q1 quarterly reports. Although actual mining has not been affected yet, medium and long-term supply elasticity may be impacted. Demand side, LFP capacity release and the peak season for new car model deliveries in Q2 are expected to continue boosting lithium carbonate demand. Overall, cost support and demand expectations are resonating, and lithium carbonate prices are expected to remain on a relatively strong trend in Q2. Lithium Hydroxide According to customs data, in March 2026, China imported 6,111 mt of lithium hydroxide, up 66% MoM and up 200% YoY. Of this, 2,927 mt came from Indonesia, accounting for approximately 48% of imports, with another 40% from Australia and South Korea. In March, China exported 3,143 mt of lithium hydroxide, up 20% MoM and down 26% YoY, of which 2,059 mt were exported to South Korea and 278 mt to Japan. Battery Materials Ternary Cathode Material In March 2026, China's ternary cathode material (NCM and NCA combined) exports reached 21,900 mt, up 103% MoM and up 163% YoY. Of this, NCM exports were 20,900 mt, accounting for 96%. In terms of export destinations, South Korea was the largest importer of NCM, with March imports of 8,500 mt; Poland, Malaysia, and Japan ranked second, third, and fourth at 3,720 mt, 2,409 mt, and 2,363 mt respectively. In addition, Germany's imports saw significant growth compared to the same period last year. China's ternary cathode material exports hit a record high in March, mainly driven by the cancellation of China's 13% VAT export rebate policy for ternary cathode material effective April 1. Four leading battery cell manufacturers in Japan and South Korea placed orders in advance, boosting demand not only for their domestic plants but also for their battery cell production sites in Southeast Asia and Europe. Beyond the rebate policy impact, EV subsidy policies in Europe also fueled strong demand growth, driving up China's ternary cathode material exports. Among them, the Nordic countries led in EV penetration rate thanks to the most generous subsidies; the UK, France, and Germany continued to serve as important sources of NEV sales support. In contrast, US NEV sales declined notably in Q1, down nearly 30% YoY, significantly impacting Q1 orders for some ex-China battery cell manufacturers targeting the North American market. Looking ahead to Q2, Europe is expected to remain the largest source of incremental ex-China ternary cathode material demand. Despite some disruption from the tax rebate policy, as more battery cell manufacturers and ternary cathode producers plan to complete construction and commence production this year and next, the outlook for European market demand remains optimistic. LiPF6 According to China Customs data, in March 2026, China's cumulative LiPF6 exports totaled approximately 4,554 mt, up approximately 161% MoM, while cumulative imports were approximately 31 mt. Export side, China's LiPF6 exports in March 2026 were approximately 4,554 mt, up approximately 161% MoM from February and up approximately 188.8% YoY. Specifically, as the VAT rebate policy for LiPF6 exports was officially canceled starting April 1, 2026, enterprises rushed to export in advance in March, driving MoM increases in exports to multiple major destination countries. Among them, exports to Poland were 1,723.602 mt (up approximately 693.63% MoM), South Korea 1,099.429 mt (up approximately 184.26% MoM), Czech Republic 460.5 mt (up approximately 237.36% MoM), and Malaysia 249.346 mt (up approximately 141.39% MoM). However, exports to the US declined — 266.146 mt (down approximately 53.70% MoM). Artificial Graphite In March 2026, China's artificial graphite imports were 673 mt, up 0.6% MoM and down 34.1% YoY. Average import price in March 2026 was 61,696 yuan/mt, up 3.9% MoM and up 10.6% YoY. Data source: China Customs, SMM In March 2026, China's artificial graphite exports were 37,525 mt, up 6% MoM and down 16% YoY. Average export price in March 2026 was 9,866 yuan/mt, up 14.4% MoM and down 7% YoY. Flake Graphite In March 2026, China's flake graphite imports were 3,905 mt, up 11% MoM and up 45% YoY. Data source: China Customs, SMM In March 2026, China's flake graphite exports were 8,118 mt, up 35% MoM and up 65% YoY. Phosphate Ore According to customs data, China's phosphate ore imports in March 2026 were 182,000 mt. March imports rose 88.2% from February's 97,000 mt, up 144.4% YoY from 75,000 mt; March total import value was $14.552 million, up 74.6% MoM from February's $8.336 million. Unit price was $79.9/mt, down 7.2% significantly from February's $86.1/mt. In March, China's phosphate ore imports mainly came from Egypt and Pakistan, with imports of 170,000 mt and 12,000 mt respectively. Affected by factors related to the Strait of Hormuz, Jordanian phosphate ore failed to be imported, though imports from other regions filled the gap. Due to hindered transportation of high-priced Jordanian phosphate ore and lack of import volume support, March phosphate ore import unit price declined from February, pulling back to below $80/mt. Cobalt Cobalt Hydrometallurgy Intermediate Products In March 2026, China's cobalt hydrometallurgy intermediate products imports were approximately 1,690 mt in physical content, down 26% MoM and down 97% YoY. Among them, imports from DRC were approximately 1,668 mt in physical content, up 10% MoM and down 97% YoY. In March 2026, the average import price of China's cobalt hydrometallurgy intermediate products was $16,730/mt in physical content, up 2.92% MoM. It was learned that cobalt intermediate products export volume from DRC increased notably in March. If the government maintains this efficient approval pace going forward, quotas for Q4 2025 and Q1/Q2 2026 will most likely be exported within the stipulated timeframe, reducing the probability of further delays. However, shipping in Africa is currently tight, with only a few miners completing small-batch vessel bookings in April. Based on a 1-2 month shipping time from South Africa to China, these intermediate products are expected to arrive at port in May-June, while intermediate products from other miners are not expected to arrive until around July. Unwrought Cobalt In March 2026, China's unwrought cobalt imports were approximately 961 mt, down 44% MoM and up 83% YoY. March imports remained at a relatively high level, mainly due to continued arrivals of export orders placed during the import window opening from late December 2025 to mid-January 2026. On average import price, China's unwrought cobalt average import price in March 2026 was $50,346/mt, up 10% MoM. Cumulative imports from January to March 2026 totaled 4,582 mt, up 206% YoY cumulatively. It was learned that as the import window gradually closed after mid-to-late January 2026, overseas traders' export willingness weakened, and refined cobalt imports in April may continue to decline MoM. Exports, China's unwrought cobalt exports in March 2026 were approximately 413 mt, up 32% MoM and down 69% YoY. By country, China's exports to the US rose slightly, with 280 mt exported to the US in March, up 13% MoM. Average export price, China's average export price of unwrought cobalt in March 2026 was $51,596/mt, down 3% MoM. Cumulative imports from January to March 2026 totaled 1,574 mt, down 52% YoY cumulatively.

According to customs data, China's antimony oxide export volume in March 2026 stood at 345.75 metric tons. On a month-on-month basis, this showed little change compared to the February export volume of 379.8 metric tons. Many market participants noted that China's antimony oxide exports have remained at a level of a few hundred metric tons per month over the past several months, with no significant improvement in the export trend. This also reflects a lack of strong willingness to export along the industrial chain. It is anticipated that the total antimony oxide export volume for the full year will be significantly lower than last year on a month-on-month basis.

Customs data shows that China's imports of other antimony ores and concentrates reached 9,263.96 metric tons in March 2026, continuing to rise from the February import volume of 6,693.67 metric tons on a month-on-month basis, and surpassing the 9,000-metric-ton mark for the first time in recent years. Market participants stated that given the narrowing price gap between domestic and international markets, the increase in antimony ore imports is reasonable. However, many market participants also indicated that the long-term tight supply trend for imported antimony raw materials is expected to persist in the future.

According to customs data, China's bismuth trioxide export volume in March 2026 stood at 1,100.23 metric tons, compared to 753.74 metric tons in February 2026, showing a continued month-on-month increase. Looking at the overall trend in export volumes, from September 2025 onward, China's bismuth trioxide exports have increased almost every month, indicating that domestic exporters remain highly motivated and overseas demand is also rising significantly.

As of April 24, the average domestic zinc concentrate TC dropped to 1,050 yuan/mt in metal content, and the imported zinc concentrate TC fell to -$36.13/dmt. Overall, zinc concentrate TCs continued to decline, with imported zinc concentrate TCs deepening further into negative territory. In May, domestic zinc concentrate TCs in multiple regions plan to further drop to three-digit levels.

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.
