China’s carbon fiber localization drive has gained a critical institutional boost. In July 2026, the country’s first national standard for polyacrylonitrile (PAN) precursor equipment— Terminology, Classification and Model Designation Method for Polyacrylonitrile Fiber Production Complete Equipment —was officially approved, set to take effect on February 1, 2027. Jointly authored by Zhejiang Jinggong Integrated Technology Co., Ltd. and Zhejiang Huachuang Carbon Fiber Technology Co., Ltd., this standard follows the carbonization equipment national standard implemented in June 2025, marking another milestone in the standardization of core carbon fiber equipment.
What the Standard Fills
Carbon fiber quality heavily depends on its precursor—PAN fiber. The strength and stability of the precursor directly determine the final carbon fiber’s performance, while the precision and intelligence of precursor production equipment influence yield and production costs. For years, China lacked unified specifications for precursor equipment, leading to inconsistent terminology, classification, and model naming. This caused inefficiencies in line design, equipment procurement, and supply chain coordination. The new standard unifies terminology, classification, and model designation across the entire process—from polymerization, spinning, stretching, and drying to solvent recovery—filling a critical gap in precursor equipment standardization.
For equipment manufacturers, standardized naming reduces technical communication costs and procurement errors. For carbon fiber producers, uniform classification enables faster equipment comparison and optimized line configuration. For the entire supply chain, a consistent specification system facilitates equipment interchangeability and maintenance, lowering long-term operational costs.
From Precursor to Carbonization: A Closed-Loop Standardization
Notably, this is not Jinggong’s first involvement in carbon fiber equipment standards. In June 2025, its-led standard for carbonization production equipment took effect. Now, both critical stages—precursor preparation and carbonization—are covered by national standards, creating a unified system for China’s entire carbon fiber equipment chain.
From an industry perspective, this dual-standard framework bridges information gaps between upstream and downstream. With precursor equipment standards in place, carbonization equipment suppliers can better understand preceding process parameters and optimize furnace design. Conversely, precursor equipment makers can refine spinning and stretching processes based on carbonization requirements. This bidirectional synergy is key to moving from isolated breakthroughs to system integration in the carbon fiber sector.
Impact on Industrial Clusters
The implementation timeline—February 2027—provides a six-month transition period. For carbon fiber clusters in Zhejiang, Jiangsu, and Shandong, this is both a window for technical upgrades and a catalyst to phase out outdated capacity. Small and medium enterprises still using non-standard, customized equipment will face pressure to update or retrofit. Leading firms with standardized production capability, meanwhile, can widen cost advantages through scale.
Jinggong has stated it will continue to work with Huachuang to promote the two national standards, advance group standards, and tackle bottlenecks in large-tow and high-performance PAN precursor and carbonization equipment. This signals that standardization is just the starting point; the real competition lies in equipment breakthroughs for large-tow and high-performance carbon fibers.
