Current Spot Price Trends of Graphite Electrodes
Recent market data indicates that UHP 600mm graphite electrodes are trading between 2,000–2,800 per ton, depending on quality, supplier, and regional demand. Prices have seen moderate volatility due to:
Supply constraints from major producers exiting key markets (e.g., Resonac’s shutdown of China/Malaysia plants).
Rising demand from EAF steelmakers, especially in Asia, where scrap-based steel production is expanding.
Raw material costs, including needle coke and petroleum coke, which impact production expenses.
The global steel sector is increasingly adopting EAF technology for its lower carbon footprint, driving demand for UHP electrodes. With China and India leading in steel output, their procurement strategies significantly affect spot prices.
Supply Chain Disruptions
Recent exits by major players have tightened supply, benefiting manufacturers like Rongsheng Graphite Electrode Manufacturer. Reduced competition in Asia could lead to higher price stability or increases.
Raw Material and Energy Costs
Needle coke prices (a key component) remain high due to limited suppliers.
Energy-intensive production (requiring 3,000°C+ graphitization) means electricity costs directly impact pricing.
Inventory and Logistics
Wooden packaging and shipping delays (e.g., from Chinese ports) add to costs.
Just-in-time purchasing by steel mills can cause short-term price spikes.
Future Market Outlook
Analysts predict UHP graphite electrodes will see 5–7% annual price growth through 2030, driven by:
