According to reports, on the 26th, the Executive Management Committee of Brazil’s Foreign Trade Chamber (Gecex) decided to implement a four-month zero-tariff policy on 191 electronic and information technology products for which import duties had previously been increased, in order to reduce industrial costs and ensure supply in China. According to Brazil’s Ministry of Development, Industry, Trade and Services, the tariff reduction covered products including smartphones, computer equipment, and electronic components. In early February this year, the Brazilian government raised import tariffs on more than 1,200 electronic products, significantly affecting the mobile phone industry, household appliances, and medical equipment; in late February, it adjusted its tariff policy and applied zero tariffs to 105 of those items.

[Multiple Bearish Factors Stall the Uptrend; China’s Tantalum Market Undergoes Short-Term Adjustment While Medium and Long-Term Support Remains Solid] Recently, the sustained upward momentum in China’s tantalum products market came to a halt, with the overall market entering a phase of temporary consolidation and adjustment. Upward momentum slowed markedly in the short term, mainly due to three core factors: the transmission of macro sentiment, changes in circulating supply, and weakening raw material costs.

As a niche yet high-strategic rare metal, hafnium (Hf, atomic number 72) lags behind common metals like copper in public awareness, but its unique physicochemical properties make it irreplaceable for nuclear power, aerospace, semiconductors and other high-end fields. This concise breakdown covers its core traits, supply dynamics and critical applications to highlight its underrecognized role in advanced manufacturing. I. Core Properties A silver-gray, high-melting-point transition metal, hafnium exists solely as a zirconium-associated metal—no independent ore deposits. The near-identical atomic radius and chemical properties of zirconium and hafnium make separation/purification highly challenging, the root of its scarcity.Key strengths for harsh industrial use: 2233℃ melting point, exceptional high-temperature oxidation/structural stability Strong room-temperature plasticity, balanced strength and toughness Superior corrosion resistance (insoluble in dilute acids/alkalis, soluble only in hydrofluoric acid/aqua regia) ~600x higher thermal neutron absorption than zirconium (ideal for nuclear reactor control) High dielectric constant of hafnium oxide (critical for advanced semiconductors) Carbides/nitrides (melting point >2900℃) for ultra-high-temperature ceramics and hard alloys II. Supply & Scarcity Resources: Extremely scarce (crustal abundance ~3 ppm), exclusively tied to zirconium ores. Global resources concentrated in Australia, South Africa, the U.S. and Brazil; China faces low hafnium content in domestic zirconium ores, leading to high external dependence. Supply: Production hinges on zirconium smelting, with zirconium-hafnium separation as a core technical barrier. Only a handful of global players produce high-purity (nuclear/electronic-grade) hafnium at scale, forming an oligopoly. Annual output is ~hundreds of tons, with ultra-low supply elasticity—supply disruptions trigger sharp price swings. Ⅲ. Irreplaceable Core Applications Demand is rigid (no cost-effective substitutes) across high-end sectors: Nuclear Industry: Preferred material for pressurized water reactor control rods, regulating reaction rates and ensuring safety. Driven by global nuclear power revival, demand is steadily growing. Aerospace: Key nickel-based single-crystal superalloy additive, boosting high-temperature creep strength and lifespan for aero-engine turbine blades, combustors and rocket nozzles. Semiconductors: High-purity electronic-grade hafnium oxide overcomes silicon dioxide’s miniaturization limits, reducing leakage current and enabling advanced-node chip production—a key growth driver. Other High-End Fields: Used in cutting tool coatings, special electronic components, corrosion-resistant materials and emerging hydrogen storage research, with expanding use cases. Ⅳ. Conclusion Hafnium is a "scarce niche metal with rigid high-end demand," holding irreplaceable strategic value in China’s key industries (nuclear power, aerospace, semiconductors). The global market remains in long-term tight supply-demand balance, and its strategic and market value will rise alongside global advanced manufacturing upgrades.

SMM March 13: This week, China’s domestic tungsten market exhibited high-level oscillations with intensified supply-demand competition. Multiple mines put products up for auction during the week, but transactions were bleak.As of March 13, tungsten prices remained largely stable, yet market sentiment became extremely divided.

New Zealand recycling technology company Mint Innovation has partnered with electronics manufacturers to recover copper from electronic waste and reuse it in the production of specific electronic components. The initiative demonstrates the potential of closed-loop recycling within the electronics industry while reducing reliance on primary copper mining. Industry observers believe similar models could gradually expand across global electronics supply chains in the coming years.

On Feb 24, 2026, China placed 20 Japanese firms, including Subaru, on an export control watchlist for unverifiable end-use of dual-use items. This signals tighter controls on critical minerals and tech amid geopolitical and supply chain shifts. The analysis examines the firms' supply chain roles and the long-term industrial implications.
