Graphitized Petroleum Coke (GPC) remains an important carbon additive for steelmaking, foundry production and other metallurgical applications. In 2026, the GPC market is being influenced by several factors at the same time, including petroleum coke feedstock costs, graphitization expenses, electricity prices, steel and foundry demand, low-sulfur material availability and international freight.
For buyers, this means that the GPC price trend cannot be explained by a single number. A quotation for 98.5% fixed carbon GPC with 0.5% sulfur is not directly comparable with a low-sulfur 99%+ product. Particle size, nitrogen, ash, moisture, packaging and delivery terms can also change the final commercial value.
Recent market information illustrates this point. Asian Metal has recently listed Chinese graphitized petroleum coke at around RMB 3,350–3,450/MT EXW China for C 98.5% min, S 0.5% max, 1–5 mm, while its FOB indication for the same specification was around USD 515–530/MT. These figures are market references rather than universal transaction prices, and buyers should request a specification-specific quotation before making purchasing decisions.
1. What Is Driving the GPC Price Trend in 2026?
The first factor is the cost of the raw material.
GPC is produced through high-temperature graphitization of suitable petroleum coke. Consequently, changes in the petroleum coke market can influence the cost structure of GPC.
The petroleum coke market itself has shown differences between grades. SMM reported in July 2026 that low-sulfur petroleum coke in China was receiving stronger support, while some medium- and high-sulfur grades faced more pressure. Refinery pricing and downstream purchasing activity were both influencing market conditions.
This distinction is important for GPC buyers because low-sulfur feedstock is generally more valuable when producing higher-purity carbon materials.
2. Electricity and Graphitization Costs
Unlike ordinary calcined petroleum coke, GPC requires graphitization.
The graphitization process requires very high temperatures and substantial electricity consumption.
Therefore, electricity prices and furnace utilization can affect the production cost of GPC.
When electricity and operating costs rise, producers may attempt to increase quotations. However, the final price still depends on market competition.
If downstream demand is weak, suppliers may have limited ability to transfer the entire cost increase to customers.
This creates an important distinction between:
production-cost pressure
and
actual market price movement.
The two do not always change at the same speed.
3. Low-Sulfur GPC Is Receiving More Attention
The market is becoming increasingly segmented by quality.
For general steelmaking applications, a buyer may accept a standard GPC specification.
For higher-quality steel, foundry applications or processes where sulfur and nitrogen must be controlled, customers may request low-sulfur and low-nitrogen material.
This can result in a noticeable price difference between standard and premium grades.
Industry suppliers have also highlighted increasing interest in low-sulfur, low-nitrogen GPC for high-end foundry and steelmaking applications.
Therefore, the phrase "GPC price" should always be followed by the actual specification.
4. Demand From Steelmaking
Steelmaking remains one of the key application areas for GPC.
GPC is used as a recarburizer to increase carbon content during steel production.
Demand can therefore be influenced by:
- Crude steel production
- Electric arc furnace output
- Foundry activity
- Pig iron availability
- Scrap consumption
- Carbon adjustment requirements
Electric arc furnace steelmaking is particularly relevant because EAF producers rely heavily on recycled steel and may need carbon additives to adjust melt chemistry.
The broader graphite electrode market also remains linked to EAF steelmaking. A 2026 market report estimated that EAF steelmaking would account for a large share of graphite electrode demand, highlighting the continuing importance of electric steel production in the carbon-material supply chain.
5. Foundry Demand
The foundry industry represents another important source of GPC demand.
Foundries need carbon adjustment materials to control the chemistry of molten iron.
The required specification can differ considerably from one foundry to another.
Some customers prioritize:
high fixed carbon
while others place greater emphasis on:
low sulfur + low nitrogen + low ash + fast carbon recovery.
This explains why two products with similar fixed-carbon levels can still receive different quotations.
6. Why Fixed Carbon Is Not the Only Price Factor
A common purchasing mistake is to compare only fixed carbon.
For example:
Product A:
Fixed Carbon: 98.5%
Sulfur: 0.5%
Ash: low
Size: 1–5 mm
Product B:
Fixed Carbon: 99%
Sulfur: 0.03%
Ash: very low
Size: 1–3 mm
Product B will normally serve a more demanding application and may have a significantly different production cost.
Therefore, procurement departments should compare the entire COA rather than one number.
7. International GPC Price Reference
International buyers should distinguish between:
- EXW
- FOB
- CFR
- and
- CIF
- prices.
For example, an FOB China price includes export-side logistics but does not represent the same landed cost as CIF Europe.
Freight can significantly change the final cost for buyers in Europe, North America, South America or the Middle East.
A professional RFQ should therefore include:
GPC grade + fixed carbon + sulfur + nitrogen + ash + size + quantity + destination + Incoterm.
8. What Could Support GPC Prices?
Several market factors could provide support to GPC prices.
Tight low-sulfur supply
Premium low-sulfur feedstock can become more expensive when availability is limited.
Higher electricity costs
Graphitization is energy intensive.
Strong steel demand
Higher steel production can support recarburizer demand.
Growing carbon-material demand
Demand from graphite and battery-related industries can influence high-quality carbon material supply chains.
CRU's 2026 commodity outlook specifically expects GPC and CPC prices to remain elevated, citing strong battery production, rising demand for low-sulfur GPC in China and growing aluminum demand.
9. What Could Put Pressure on Prices?
The opposite factors should also be monitored.
Prices may face pressure when:
- Petroleum coke supply increases
- GPC production capacity expands
- Steel demand weakens
- Foundry activity slows
- Inventories rise
- Freight costs decline
- Buyers postpone replenishment
This is why buyers should avoid assuming that prices will continuously increase.
10. How Should Buyers Purchase GPC in 2026?
A practical purchasing strategy is to divide annual demand into several procurement periods.
Instead of purchasing the entire annual requirement at one time, buyers can consider:
Long-term contract + quarterly purchasing + spot replenishment.
This can reduce the risk associated with purchasing at a temporary market high.
However, inventory costs should also be considered.
Holding excessive GPC inventory can tie up working capital and increase storage requirements.
11. GPC Packaging and Storage
Common export packaging includes:
- 25 kg bags
- 500 kg bags
- 1 MT jumbo bags
- Palletized bags
- Customized export packaging
GPC should be protected from contamination and excessive moisture.
The storage area should ideally be:
dry + covered + ventilated + clean.
Products should not be stored directly on wet floors.
Different GPC grades should also be separated to avoid cross-contamination.
12. GPC Price Outlook
The 2026 market is likely to remain differentiated rather than moving uniformly.
Standard grades may respond primarily to petroleum coke and steel demand.
Low-sulfur and high-purity grades may receive additional support from tighter feedstock availability and more demanding applications.
Therefore, buyers should monitor the specific GPC grade they actually consume rather than relying on a general market index.
