Chinese domestic tungsten spot prices held firm in mid-June 2026 amid persistently muted trading. At a USD-CNY spot rate of 7.21, 65% black tungsten concentrate was quoted at $72,120-73,510 per mtu, while domestic ammonium paratungstate (APT) settled steadily at $110,960/dmt. Spot prices have moved less than 1% over the past two weeks, with end-users and traders staying on the sidelines. Price and Liquidity Divergence Price Floor Supported by Tight Raw Material Supply Domestic mine environmental compliance checks and falling Myanmar tungsten ore inflows have constrained raw material supply, keeping mine operators firm on offer prices. Midstream smelters are running modest operating rates with balanced APT inventories, showing no urge for fire sales. State reserve procurement expectations also cap downside price pressure across the complex. Thin Trading Stemming From Weak End-User Demand Cemented carbide downstream demand remains sluggish. Cutting tool consumption from construction machinery and mold sectors has entered seasonal lulls, while incremental demand for new-energy tungsten wire and PCB micro-drills undershot market forecasts. Downstream fabricators completed pre-season inventory builds earlier and now adopt hand-to-mouth purchasing. Secondary traders have also pared spot turnover, leading to a tight, illiquid spot market. Near-Term Market Outlook 1-2 months (Short term): Prices are set to rangebound trade. Offset supply-side support and soft demand will keep spot values unchanged, with limited trading improvement expected. Q3 2026 (Medium term): Mild upside potential remains. Peak seasonal demand from automotive and construction machinery sectors will lift tool offtake, alongside seasonal mine output curbs during flood season. Sharp price rallies are not anticipated. Market Takeaway: Industry participants are advised to maintain lean inventories and avoid speculative positioning amid prolonged low liquidity.

Since 2026, the price of tungsten carbide, a core raw material for road milling teeth, has shown a trend of "sharp surge followed by high-level volatility", becoming a key variable disrupting the global road milling teeth industry. Data shows that the price of tungsten carbide soared from 143,000 yuan/ton at the beginning of 2025 to 1.03 million yuan/ton in March 2026, a staggering increase of 600%. Although it experienced a technical correction to 914,000 yuan/ton in April, it still remains in an historically high range. This price fluctuation has a direct impact on the road milling teeth industry—since tungsten carbide accounts for 62%-68% of the raw material cost of road milling teeth, and the proportion of raw material costs for cemented carbide tools has now risen to over 80%, every 10% increase in tungsten carbide prices will lead to an average increase of 5.8%-6.3% in the unit marginal cost of road milling pick.​ For China's road milling teeth market, the cost pressure is particularly prominent. The market size of China's road milling teeth reached 4.36 billion yuan in 2025, a year-on-year increase of 8.2%, of which cemented carbide road milling teeth accounted for 68.5%. The average domestic price of tungsten carbide in 2025 had reached 238 yuan/kg, a year-on-year increase of 5.3% compared with 2024, and the sharp price surge in 2026 has further compressed the profit margins of enterprises. Small and medium-sized manufacturers have been hit the hardest—some manufacturers lacking the ability to lock in raw material prices have hesitated to accept orders. Meanwhile, the Q1 2026 financial reports of leading enterprises show that their gross profit margins have dropped by an average of 4-6 percentage points compared with the same period last year.​ Supply-Demand Gap Drives Price Surge, Multiple Factors Support High-Level Operation​ The core logic behind this sharp rise in tungsten carbide prices is the supply-demand imbalance characterized by "rigid supply contraction + multi-point demand outbreak". On the supply side, as the world's largest producer of tungsten resources, China reduced its tungsten mining quota by 8% year-on-year in 2026. Moreover, it implemented export controls on 25 types of tungsten products (one license per order) starting from February, leading to a sharp drop of 35.99% in export volume year-on-year in January-February. Global tungsten inventories can only last for 15-20 days, reaching an historical low. Although China accounts for over 80% of global tungsten carbide production, it has long faced structural problems of overcapacity in mid-to-low-end products and reliance on imports for high-end products, making it difficult to quickly respond to the growth in high-end demand.​ On the demand side, there is a "traditional + emerging" dual-driver: on one hand, the global infrastructure recovery has driven steady growth in demand from traditional application areas such as road milling teeth and mining tools. In 2026, global tungsten demand reached 145,000 tons, while supply was only 126,500 tons, resulting in a gap of 18,500 tons. On the other hand, the explosive demand from emerging areas such as photovoltaic tungsten wire and AI server PCB micro-drills has further squeezed the tungsten carbide resource quota of the road milling teeth industry. International investment banks generally predict that the supply-demand gap of tungsten carbide will continue to expand during 2026-2028, and the price center is expected to remain at 900,000-1.1 million yuan/ton, showing a long-term trend of being prone to rise and difficult to fall.​ Accelerated Industry Differentiation, Technological Innovation and Resource Integration as Key to Breaking the Dilemma​ Faced with the new normal of high tungsten carbide prices, the road milling teeth industry is undergoing accelerated differentiation, and enterprises have adopted multiple strategies to hedge against cost pressures. In terms of resource guarantee, leading enterprises have locked in the supply chain through vertical integration. For example, leading enterprises such as China Tungsten & Hightech Materials Co., Ltd. and Xiamen Tungsten Industry Co., Ltd. have controlled the procurement cost of tungsten carbide to 8%-12% below the industry average by participating in the shares of tungsten mines and signing long-term strategic agreements. At the same time, the recycling system for waste asphalt milling teeth has developed rapidly—the average industry recycling rate reached 55% in 2025, and the application of recycled tungsten carbide has effectively reduced the dependence on raw materials.​ Technological innovation has become the core path for cost reduction and efficiency improvement. On one hand, enterprises are optimizing product formulas, improving the utilization rate of tungsten carbide and reducing the consumption per unit product through technologies such as submicron grain refinement and gradient structure design. On the other hand, they are upgrading production processes—the application of technologies such as automatic powder pressing and intelligent vacuum sintering has reduced the material loss rate from the traditional 15% to below 8%. Some leading enterprises have also launched cost-effective alternative solutions, such as improving the wear resistance of road milling teeth through nano-composite coating technology, which extends the service life of products by 30%-50% without increasing the dosage of tungsten carbide, indirectly reducing the unit construction cost.​ Reshaped Market Pattern, High-Endization and Differentiation Become Competitive Focus​ Cost pressure has forced the industry pattern to evolve towards "the strong getting stronger". The CR10 concentration ratio of China's road milling teeth industry has risen to 38.7% in 2025, and is expected to exceed 40% in 2026. International brands still dominate the high-end road milling teeth market (such as airport runways and high-grade highway projects) relying on their technical accumulation and global supply chain advantages—their average product price reaches 132.7 yuan/piece, 53.6% higher than that of domestic high-end products. Meanwhile, domestic leading enterprises are accelerating the replacement of imports in incremental markets such as highway maintenance and urban road renovation through cost-performance advantages and rapid customization services. They are also making breakthroughs in high-end fields such as PDC road milling teeth—the market share of domestic PDC road milling teeth has increased from 12% in 2020 to 22.3% in 2025.​ For small and medium-sized enterprises, differentiated competition has become the key to survival. Some enterprises focus on regional segmented markets and develop customized products for special working conditions such as wet pavements and gravel subgrades. Others are deeply engaged in the export market, leveraging the infrastructure dividends along the "Belt and Road" to transform their cost-performance advantages into international competitiveness. The export volume of China's road milling teeth exceeded 980 million yuan in 2025.​ Future Outlook: Normalized Cost Pressure, Green Innovation Leads Long-Term Growth​ Looking ahead to 2026-2030, the high-level operation of tungsten carbide prices will become the norm in the road milling teeth industry, and the industry's growth logic will shift from "scale expansion" to "value enhancement". It is expected that the market size of China's road milling teeth will grow steadily at a CAGR of 7.8%-8.5%, and is expected to exceed 6.5 billion yuan by 2030. However, the growth momentum will come more from product high-endization and service value-added rather than pure quantity expansion.​ At the policy level, the national strategic deployment for the independent controllability of key basic materials will continue to strengthen. The green and intensive transformation of the tungsten carbide industry chain will receive more policy support, and enterprises with low-carbon production processes and ESG compliance capabilities will gain competitive advantages. At the technical level, innovative directions such as intelligent cold milling teeth (with built-in wear monitoring sensors) and circular economy models (recycling and remanufacturing of waste tools) will become industry hotspots, promoting the transformation of road milling teeth from "passive consumables" to "active production factors".​ Overall, although the fluctuation of tungsten carbide prices has brought short-term pains to the road milling teeth industry, it has also accelerated industry reshuffling and transformation and upgrading. Enterprises with resource integration capabilities, technological innovation strength and differentiated competitive advantages will seize opportunities in the wave of cost restructuring, driving the global road milling bit industry towards high-quality and sustainable development.

As global urbanization accelerates and existing road networks demand more maintenance, road milling teeth—core consumables for road construction—see sustained growth. The global road construction equipment market hit 28.05 billion in 2026, projected to reach 34.78 billion by 2035 (CAGR: 2.42%). Road milling teeth, a critical component, outpace the industry’s average demand growth. China stands out with a 2025 market size of RMB 4.36 billion (+8.2% YoY), expected to surpass RMB 4.7 billion in 2026. Key drivers: ongoing investment in highway renovations, urban road expansions, and airport runway upgrades, plus "regular maintenance" policies for transportation assets—all boosting demand for high-performance asphalt milling picks. Material & Process Upgrades Enhance Competitiveness Material innovation is central to the industry. Traditional plain alloy steel can no longer meet high-intensity construction needs; leading brands now widely use tungsten carbide tips + high-strength alloy steel substrates. Vacuum brazing strengthens the bond between tip and tooth body, cutting down on tooth loss, chipping, and excessive wear. Surface carbonization, quenching, and tempering have improved impact and corrosion resistance. These advanced products adapt to wet pavements, old cement roads, and gravel subgrades, extending service life by 30%-50% vs. traditional models and reducing replacement frequency. Structural Optimization & Customization Become Mainstream Design refinements focus on tooth angle, shank specs, and assembly. Classic conical, flat-headed, and arc-shaped milling teeth are now scenario-specific: sharper tips for asphalt pavement (boosting cutting efficiency) and thicker carbide tips/reinforced shanks for cement pavement (enhancing impact resistance). Industry-wide interface standardization enables compatibility with major milling machine brands (Wirtgen, Caterpillar, XCMG), expanding application scope. Market Competition Intensifies, Shifting to High-End Segments The global market has three key player groups: tech-driven international giants, cost-competitive domestic leaders (e.g., in China), and regional SMEs. International brands dominate high-end projects (airport runways, high-grade highways) via mature R&D and global after-sales networks. Domestic manufacturers in emerging markets are catching up through tech innovation and scale, narrowing performance gaps while retaining price advantages.
