Since the onset of November, international tin prices have refrained from a one-sided, steep upward surge. Even so, the record peak of RMB 285,800 per ton (as of November 10) has triggered urgent cost concerns across downstream sectors.
Supply Scarcity: The Core Driver Behind Price Surge
Global tin ore supply has been squeezed by a combination of factors: delayed resumption of mining operations in Wa State, Myanmar; Indonesia’s sustained crackdown on unauthorized mining activities; and geopolitical tensions sweeping across African regions. Against this backdrop, consistent demand from high-growth sectors like semiconductors and new energy has offered robust underpinning for the lingering high prices.
Cost Impacts Penetrate Straight to Production Floors
For manufacturers in the sintered diamond tool industry, the elevated tin prices are translating directly into higher matrix costs. As a critical bonding metal, tin delivers three non-substitutable functions: lowering sintering temperatures, fine-tuning the toughness and hardness of the matrix, and sealing pores to boost holding capacity. Fluctuations in its cost directly influence both product performance and profit margins.
Tackling High Costs: Combining Strategic Procurement and Technical Oversight
We propose a two-pronged strategy for enterprises to mitigate cost pressures. First, develop a flexible procurement system: proactively boost inventory levels when prices dip to relatively lower ranges, and forge long-term strategic partnerships with key suppliers to secure stable supply chains. Second, initiate formula optimization initiatives: conduct precise evaluations to determine the minimum effective tin content required, and actively explore process upgrading pathways that cut costs while enhancing efficiency.
The future trajectory of tin prices will play a decisive role in shaping the cost structures and competitive edges of downstream enterprises. Proactively revamping procurement strategies and expediting technical optimization efforts have become indispensable measures for businesses to rein in costs and protect profit margins.
