The carbon fiber industry is undergoing a 'standard-driven' upgrade. According to publicly available industry data, a national standard for complete sets of carbon fiber precursor production equipment has been approved and will take effect in February 2027. This is not only the first national technical specification in this niche field but also marks a shift from fragmented standards to a fully integrated equipment standard system for China's carbon fiber industry.
For the precursor segment, which has long relied on imported equipment and experience-based production, the unification of terminology and classification has immediate implications. Production line designers, equipment manufacturers, and end users will now share a common technical language, systematically alleviating issues such as selection errors and high adaptation costs caused by chaotic model designations.
Filling a Critical Gap
The newly approved standard focuses on complete sets of equipment for polyacrylonitrile (PAN) precursor production, covering the entire process from polymerization, spinning, drawing, drying, to solvent recovery. Public data from the National Bureau of Statistics shows that PAN precursor accounts for about 50%-60% of carbon fiber production costs, and its quality directly determines the strength and stability of carbon fiber. However, for a long time, the domestic precursor equipment sector lacked unified norms, with equipment terminology, classification, and model designations varying widely, leading to inefficiencies in production line design, equipment procurement, and supply chain coordination.
The standard was led by Zhejiang Jinggong Integrated Technology Co., Ltd. and Zhejiang Huachuang Carbon Fiber Technology Co., Ltd. It follows the 'Terminology, Classification, and Model Designation Method for Complete Sets of Fiber Carbonization Production Equipment' (implemented in June 2025), marking another national standard in the core equipment field of carbon fiber. With this, both key production stages—precursor and carbonization—now have unified national standards, forming a coherent standard system for China's entire carbon fiber equipment chain.
Industry Impact: Accelerating the Shift from Capability to Quality
The ripple effect of standard unification on the industrial chain is significant. For upstream equipment manufacturers, unified classification and model designation methods will reduce repetitive investment in product R&D and accelerate the launch of modular, standardized equipment. For downstream carbon fiber producers, the cycle for equipment selection and production line expansion is expected to shorten, and the certainty of improving yield rates will increase.
The deeper impact lies in providing a technical basis for substituting imported equipment with domestic alternatives. Previously, carbon fiber companies often referenced foreign standards when purchasing precursor equipment, leaving domestic equipment at a disadvantage due to the lack of a unified evaluation system. With the national standard in place, domestic equipment now has an official 'identity card' in terms of terminology and performance indicators, making it easier to gain user trust.
Furthermore, this standard will synergize with the existing carbonization equipment standard, laying the groundwork for intelligent and large-scale production across the entire carbon fiber process. Industry analysts point out that with a comprehensive standard system, breakthroughs in core bottlenecks such as large-tow and high-performance PAN precursor and carbonization equipment will follow a clearer path, helping China's entire carbon fiber industry chain achieve security and control.
