III. Core Trend Analysis
High Concentration of Suppliers
Transaction records show that Shanghai Xiaoshudian Chemical Technology Co., Ltd. holds a dominant position in the supply chain. This supplier secured the vast majority of awards across all 5 publicly disclosed successful batches. Additionally, the cooperation frequency and single-batch procurement volume have increased over time, with the per-batch quantity rising from 500 kg to 800 kg.
Stepped Surge in Procurement Unit Prices
The unit price of the commodity witnessed a notable stepped upward trend. The average unit price was RMB 12,150 per kg in December 2025, climbing to RMB 13,915 per kg in January 2026 and RMB 19,890 per kg in April 2026, before hitting RMB 23,250 per kg in May 2026. Within six months, the procurement price of the raw material surged by nearly 90%, almost doubling, indicating mounting upward price pressure across the upstream raw material sector.
According to statistics from SMM, China’s domestic output of ammonium perrhenate reached approximately 24,000 kg in 2025, while the consumption of rhenium metal stood at around 15,000 kg, equivalent to 21,000 kg of ammonium perrhenate. On paper, the market still saw a supply surplus. Nevertheless, actual delivery data reveals that some producers held back inventories, leading to a real market supply far below the 24,000 kg output figure.
Overall, large institutional buyers have ramped up stockpiling and continued to deplete circulating inventory. Coupled with new tender demands released by Sinopec, the supply-demand gap for high-purity ammonium perrhenate is narrowing. Prices are poised to stay firm with an upward bias, and available goods will further concentrate among core suppliers and major end-users.
