The localization of China's carbon fiber industry is deepening from materials to equipment. A newly approved national standard has unified the terminology, classification, and model numbering for complete polyacrylonitrile (PAN) precursor production equipment, essentially completing the standard system for the entire carbon fiber equipment chain.
This standard, led by Zhejiang Jinggong Integrated Technology Co., Ltd. and Zhejiang Huachuang Carbon Fiber Technology Co., Ltd., is scheduled to take effect on February 1, 2027. It follows the national standard for carbonization equipment that came into effect in June 2025, marking the second national standard in core carbon fiber equipment led by Jinggong Technology.
The Historical Cost of Standard Gaps
PAN precursor is the precursor material for carbon fiber, and its quality directly determines the strength and stability of the final product. In the entire carbon fiber production process, the precursor stage has the highest technical barriers, and equipment precision and intelligence levels directly affect mass production yield and costs. Previously, China's precursor equipment sector lacked unified specifications—equipment terminology, classification, and model naming varied widely among companies, leading to inefficiencies in production line design, equipment procurement, and supply chain coordination.
The hidden costs of this standard gap were significant. Incompatibility of equipment interfaces between different manufacturers required extensive customization for new production lines. Spare parts could not be shared, driving up maintenance costs. More importantly, the industry lacked a unified performance evaluation benchmark, forcing equipment selection to rely on experience rather than data, increasing investment risk.
From Precursor to Carbonization: A Closed-Loop Standard
This new national standard for the first time unifies terminology, classification, and model numbering for the entire process from polymerization, spinning, drawing, and drying to solvent recovery. This means the two most critical stages of carbon fiber production—precursor preparation and carbonization—are now fully covered by national standards.
For the industry chain, the direct impact of standard unification is improved reproducibility. Equipment manufacturers can design and produce in a modular fashion based on the standard, reducing the share of customization. Carbon fiber producers gain a clear reference for equipment selection during new project planning, potentially shortening production line construction cycles. At a macro level, the unified standard also lays the foundation for industry data benchmarking, energy efficiency assessment, and smart manufacturing upgrades.
Jinggong Technology stated it will continue to collaborate with Huachuang Technology, leveraging the two national standards while promoting group standards, focusing on key bottlenecks such as large-tow, high-performance PAN precursor, and carbonization equipment. This signals that building the standard system is just the first step; subsequent technical breakthroughs and industrialization are the real challenges.
Practical Impact on Buyers and Foreign Trade Companies
For downstream carbon fiber buyers, equipment standard unification means greater supply chain transparency. Previously, comparing suppliers' capacity and quality was difficult without a common equipment performance reference. After implementation, standardized model classification will reduce information asymmetry, helping buyers more accurately assess technical levels and reliability across different production lines.
For foreign trade companies, the improved domestic standard system could have dual effects. On one hand, standardized Chinese carbon fiber equipment can boost international competitiveness, especially in new material cooperation projects along the Belt and Road Initiative. On the other hand, stricter domestic standards may raise entry barriers for imported equipment, prompting overseas suppliers to adjust their product strategies.
