China's carbon fiber equipment sector has reached another standardization milestone. A new national standard for polyacrylonitrile (PAN) precursor fiber production equipment—covering terminology, classification, and model designation—has been approved and will take effect in February 2027. This follows the implementation of a carbonization equipment standard in June 2025, completing a unified national standard system for the entire carbon fiber production line.
The Industrial Logic Behind the Standard
PAN precursor fiber is the precursor to carbon fiber, and its quality directly determines the strength and stability of the final product. The production process involves multiple stages—polymerization, spinning, drawing, drying, and solvent recovery—where equipment precision and intelligence directly impact yield rates and production costs. For years, the domestic precursor equipment sector lacked unified specifications, leading to inconsistent terminology, classification, and model designations. This fragmentation hindered production line design, equipment procurement, and supply chain coordination.
The new standard, led by Zhejiang Jinggong Integrated Technology Co., Ltd. and Zhejiang Huachuang Carbon Fiber Technology Co., Ltd., standardizes terminology, classification, and model designation rules for the entire precursor production process. This is not merely a technical document; it provides a common language for upstream and downstream companies in equipment selection, production line integration, and technical communication, significantly reducing transaction costs and coordination friction.
Strategic Significance of a Full-Process Standard System
The carbonization equipment standard, also led by Jinggong Technology, has been in effect since June 2025. Now, both key stages of carbon fiber production—precursor and carbonization—are covered by national standards, creating a coherent standard system for China's entire carbon fiber equipment chain.
From an industry perspective, this standardization effort is not an isolated event. The carbon fiber industry is expanding from aerospace and other high-end applications into civil sectors such as wind turbine blades, pressure vessels, and automotive lightweighting, demanding greater equipment consistency and scalability. Unified standards enable domestic equipment manufacturers to achieve modular design and mass production, thereby reducing per-line investment costs and shortening production line construction cycles.
For buyers, standardized equipment parameters make comparisons more objective, shifting procurement decisions from experience-based judgments to quantifiable comparisons. For equipment suppliers, the standard provides clear direction for technological upgrades—products failing to comply with national classification and model designation rules will face compliance hurdles in the market.
Accelerating Supply Chain Synergy and Domestic Substitution
Jinggong Technology has stated that it will continue to collaborate with Huachuang Carbon Fiber Technology, leveraging the two national standards to promote group standards and tackle core bottlenecks in large-tow, high-performance PAN precursor, and carbonization equipment. This signals that standardization efforts are extending from terminology to technical breakthroughs.
Globally, companies like Toray and Hexcel still dominate the high-end carbon fiber market. While China's carbon fiber capacity has expanded rapidly, the stability and consistency of precursor equipment remain key constraints on yield improvement. The new standard provides a benchmark for domestic equipment makers to align with international practices and iterate systematically, accelerating the transition of domestic precursor equipment from 'usable' to 'high-performance.'
For downstream users, a complete standard system reduces procurement risks. In the past, confusion over equipment terminology often led to production line compatibility issues. The new standard will help minimize such disputes, promoting the large-scale adoption of domestic equipment in wind power, hydrogen energy, sports equipment, and other sectors.
