Philippine Nickel Ore Market: Ample Inventories at Chinese and Indonesian Smelters, Tug-of-War between Sellers and Buyers Driving Nickel Ore Prices Under Pressure Philippine nickel ore prices declined this week. Price-wise, Philippine nickel ore CIF China quotes: Ni 1.3% grade at $53-56/wmt, Ni 1.4% grade at $61-64/wmt, Ni 1.5% grade at $68-71/wmt. In addition, the 1.3% grade CIF average price from the Philippines to Indonesia was quoted at $48-50/wmt, and the 1.4% grade CIF average price at $56-58/wmt. Recently, Philippine nickel ore prices have generally faced downward pressure. In terms of supply, as the rainy season ended in major producing areas, shipments of Philippine nickel ore increased significantly. Most mines resumed normal shipping, effectively easing the previously tight supply situation. Meanwhile, demand side, large smelters from China and Indonesia were leveraging ample inventories and favorable supply availability in the market to push for lower prices. As buyers on both sides only accepted lower prices, miners had to compromise. In terms of export flows, nickel ore shipments to Indonesia were relatively low this week, indicating a slow procurement pace in the Indonesian market. Given the still-weak recovery in nickel ore shipments to Indonesia, bearish market sentiment is expected to drag nickel ore prices further down. Inventory side, as of May 8 (Friday), nickel ore inventory at Chinese ports stood at 4.55 million mt, up 150,000 mt WoW, with total port inventory equivalent to approximately 35,700 mt Ni in metal content. Demand side, China's NPI prices continued to rise overall this week, while spot transaction prices edged down to 1,146 yuan/nickel unit. The high-grade NPI market overall hovered at highs this week, with significant divergence between sellers and buyers. The price center shifted slightly lower amid the tug-of-war between cost support and weak demand, and overall market sentiment remained subdued. Smelters' continued push for lower prices on the raw material side caused the nickel ore CIF price center to shift further downward. As a result, Philippine ore FOB price support was extremely lacking. Considering destocking and maintaining trade turnover, miners are expected to make concessions in subsequent quotes. Currently, bearish sentiment dominates the market, and there remains room for further downside in prices in the short term. Prices are expected to maintain a downward trend in May. Indonesian Nickel Ore Market: Indonesian Nickel Benchmark Price Breaks Through $18,000, Extreme Weather and Policy Dynamics Intensify Price Divergence Indonesian nickel ore market prices fluctuated overall this week. Indonesia's Ministry of Energy and Mineral Resources (ESDM) officially released the nickel mineral benchmark price (HMA) for the second half of May 2026. The HMA for the first half of May was: nickel at $18,849.3/mt (up $1,047.15 from the first period of May 2026 at $17,802.14, a 5.88% increase); cobalt at $55,854/mt; iron ore at $1.58/mt; chrome ore at $6.37/mt. Currently, the CIF price of 1.6%-grade saprolite ore reached $77.8–80.8/wmt, up $3.3 from last week. The price of 1.2%-grade limonite ore was approximately $28.33/wmt, flat from last week. 2. Supply-Demand Fundamentals and Weather Impact Saprolite ore: Production from major mines is expected to edge up in May. Although Indonesia has largely entered the dry season, abnormally heavy rainfall hit the central and southern Sulawesi region mid-week. As a result, land transportation and barge transshipment plans at some small and medium-sized mines were forced to halt. Despite RKAB approval progress reaching 90%, spot supply of high-grade saprolite ore remains tight; nevertheless, market expectations for easing supply have strengthened notably compared to earlier periods. Notably, the average grade of ore accepted by smelters has begun to trend downward. Although the decline is not yet significant, some smelters have started blending low-grade ore into their raw materials to alleviate the pressure from high-grade ore shortages and surging costs. Pricing side, smelters currently primarily adopt fixed pricing or a "HPM + $7–10 premium" model. Additionally, some smelters have begun implementing uniform saprolite ore benchmark specifications (cobalt 0.05%, iron 20%, chromium 1%), regardless of differences in actual ore output from individual mines. Furthermore, composition bonuses in the market have been reduced to minimal levels, as most bonuses are already incorporated into the fixed premium. Overall, as HMA has already breached the $18,000/mt threshold and the nickel ore royalty has risen to 15%, downside room for Indonesian nickel ore prices is limited in the short term. Limonite ore: Limonite ore prices declined and did not follow the increase in the new HPM. Affected by a potential sulphuric acid supply deficit in May that could lead to MHP production cuts, limonite ore demand was under pressure. Against a backdrop of relatively stable inventory, smelters continued to push for lower prices aggressively. 3. SMM Internal Estimates: The new formula led to ore price divergence and amplified fluctuations (particularly affected by the relatively high associated cobalt content in certain ores). SMM estimates showed that the new HPM for 1.2%-grade limonite ore was approximately $49.95, already significantly higher than actual market assessed prices; the new HPM for 1.6%-grade saprolite ore was $70.83, and under the new pricing formula, price fluctuations were notably amplified due to the higher cobalt content in certain ores. Although current actual market transaction prices remain above this benchmark, the gap between the two is steadily narrowing. 4. Regulatory Quota (RKAB) and Market Outlook: Indonesia's ESDM indicated that the 2026 RKAB approval progress has reached approximately 90%. According to SMM statistics, the cumulative approved RKAB quota for Indonesian nickel ore totalled approximately 230–240 million wmt. The market widely expects the final quota to be officially finalised by month-end of April. Affected by the combined impact of expectations of RKAB quota reductions, resource uncertainty, and the shortage of high-grade ore, some smelters have already begun raising trade premiums and surcharges to secure supply sources. The market has recently been closely watching the announcement by Indonesia's Minister of Energy and Mineral Resources (ESDM) Bahlil Lahadalia on Monday (May 11, 2026) that the government will postpone its plan to impose export duties (bea keluar) on nickel downstream products in order to formulate a reasonable pricing formula that is a "win-win" for both the country and enterprises. Although this tariff is intended to drive the transformation of the nickel industry, which currently achieves only 40% deep processing, toward higher value-added products (such as moving beyond merely producing NPI), the government decided to temporarily "shelve" the proposal after hearing industry opinions.

In the manganese-based hydrometallurgy industry chain, sulphuric acid is not merely an ordinary auxiliary material, but rather a core lifeline raw material that runs through the production of all product categories, controls production costs, and influences process selection. Mainstream products such as EMM, various grades of manganese sulphate, and EMD differ vastly in production processes and have entirely distinct acid consumption structures, which also leads to completely stratified sensitivities of various manganese products to sulphuric acid price fluctuations. Every round of change in acid prices transmits from top to bottom, directly reshaping the cost structure and market dynamics of the manganese industry chain.

Lead concentrate TCs remained generally stable this week. The weekly average TC for domestic Pb50 was quoted at 300 yuan/mt Pb, while the weekly average TC for imported Pb60 was quoted at -$135/dmt. Smelters maintained mainstream quotations within the range of -$150 to -$130/dmt. As the SHFE/LME lead price ratio continued to decline, losses on lead concentrate imports widened, and smelters showed little enthusiasm for negotiating purchases, resulting in minimal actual transactions for imported ore. The biggest unexpected impact on the precious metals market this week came from the issuance of Peru's energy crisis decree. Silver prices experienced wild swings, but the price fluctuations in precious metals have not yet transmitted to the TC quotation stage for imported ore or the silver payable stage for lead concentrates. Some smelters indicated that there are no expectations of supply disruptions from Peru-sourced lead concentrates in the short term. The silver payable indicator remained stable, mainly because buyers and sellers had doubts about the sustainability of the silver price rebound, and consensus could still be reached on maintaining the current payable indicator. Although zinc concentrate TCs saw significant reductions in May due to factors such as a sharp rise in sulphuric acid prices, lead concentrate TC quotations saw almost no reduction during the same period. Multiple mining enterprises stated that lead concentrate TCs have almost no room for further decline.

Zambia banned sulphuric acid exports in September 2025 and subsequently implemented a licensing policy in March this year. Zambia's Minister of Commerce, Trade and Industry Chipoka Mulenga told Reuters on Thursday that the government had authorized Chambishi copper smelter and Mopani copper mine to resume sulphuric acid shipments after local inventory had been replenished. Mulenga also said Zambia could expand export licenses if supply conditions continued to improve. Documents seen by Reuters showed that the Ministry of National Defense also authorized chemical trader Alliswell Investment Limited to ship 5,000 mt of sulphuric acid. An industry source said Mopani had not yet received an export license. Mopani, Chambishi, and Alliswell did not respond to requests for comment.

SMM May 14: This week, trading activity among China's aluminum fluoride enterprises was moderate, with aluminum fluoride prices remaining stable. As of now, SMM aluminum fluoride prices closed at 11,480-12,000 yuan/mt; cryolite prices remained stable, with SMM cryolite quoted at 7,000-8,500 yuan/mt. Raw material side: Prices of core raw materials for aluminum fluoride showed mixed performance, while overall cost support remained relatively firm. This week, delivery-to-factory prices of 97% fluorite powder in China maintained a stable transitional pattern, with mainstream transaction range at 3,200-3,500 yuan/mt and notable regional price spreads persisting. Supply side, operating rates in northern production areas rebounded steadily, coupled with continued arrivals of Mongolian imports at ports, further easing overall market supply. As a result, high-priced cargoes faced notable transaction pressure, and some traders remained willing to cut prices to ship out goods for capital recovery purposes. Demand side, post-holiday wait-and-see sentiment among downstream markets had yet to dissipate, with insufficient momentum for new orders. Enterprise procurement mainly focused on digesting earlier contract orders, and spot trades remained sluggish. Although rising hydrofluoric acid prices provided sentiment support for fluorite, and delayed resumption of operations in Zhejiang mining areas along with locally low inventory still offered some support, the combination of ample supply and sluggish spot trades kept the overall market in the doldrums with slight weakness. Aluminum hydroxide prices edged down slightly, with the current SMM weighted average price at 1,656 yuan/mt, down 0.24% WoW. The sulphuric acid market continued to rise. Currently, raw material sulphur circulation remained tight with prices continuing to climb. Supply side, some enterprises halted for maintenance, tightening supply, while demand gradually weakened. Overall, sulphuric acid prices hovered at highs, and the market remained relatively strong. In summary, prices of core raw materials for aluminum fluoride showed mixed performance, with the overall cost center fluctuating at highs, and production pressure on enterprises remained difficult to ease. The supply side exhibited a negative cycle of rigid cost increases—deeply squeezed profitability—low willingness to operate. Recently, overall raw material costs for aluminum fluoride remained elevated, with the industry mired in deep losses and cost inversion. Enterprise production enthusiasm was significantly dampened, and the industry's overall operating rate dropped to a low of around 40%. Demand side, downstream operating aluminum capacity remained stable at highs, providing rigid floor demand for aluminum fluoride. Brief comment: This week, raw material prices in the aluminum fluoride market showed mixed performance, but comprehensive calculations indicated that raw material costs remained in a high range, significantly suppressing operating profits for producers. The industry overall maintained a "triple pressure" pattern of high costs, low profits, and low operating rates, making it difficult to effectively boost enterprise production enthusiasm. Overall, the market currently lacked clear trend-driving factors for price movements, with a stalemate in the tug-of-war between sellers and buyers. Transactions were mainly driven by rigid demand, and wait-and-see sentiment was relatively strong. In the short term, prices were expected to remain stable, with limited room for wild swings. Going forward, it is necessary to continue closely monitoring the dynamic changes on the raw material cost side, as well as the marginal adjustments in the procurement pace of downstream aluminum enterprises.
