The standardization of carbon fiber production equipment in China has reached a critical milestone. A new national standard focusing on complete sets of equipment for polyacrylonitrile (PAN) precursor production—titled 'Terminology, Classification, and Model Numbering Method for Complete Sets of Polyacrylonitrile Fiber Production Equipment'—has been officially approved and will take effect on February 1, 2027. The standard was jointly developed by Zhejiang Jinggong Integrated Technology Co., Ltd. and Zhejiang Huachuang Carbon Fiber Technology Co., Ltd., marking the first time that both the precursor and carbonization stages of carbon fiber manufacturing are governed by a unified national standard system.
From Terminology Chaos to Unified Coding
For years, the domestic PAN precursor equipment sector lacked a widely accepted set of terminology and classification rules. Different suppliers used varying names for similar components and adopted inconsistent model numbering logic. This directly led to high communication costs during production line design, difficulties in precise equipment procurement, and frequent compatibility issues during line integration and maintenance for downstream carbon fiber producers. The newly approved national standard systematically unifies the terminology, classification, and model numbering rules for the entire precursor production process, including polymerization, spinning, drawing, drying, and solvent recovery. Starting in 2027, equipment manufacturers, carbon fiber producers, and engineering design firms will share a common technical language, significantly improving supply chain coordination efficiency.
A Complete Standard Framework Takes Shape
This is not Jinggong Technology's first foray into carbon fiber equipment standardization. The company previously led the development of the national standard for carbonization production equipment, which took effect in June 2025. With both the precursor and carbonization standards now in place within less than two years, the two most technically demanding and capital-intensive stages of carbon fiber manufacturing are fully covered by national standards. For the industry, this means a traceable and reusable benchmark for equipment selection, production line construction, and maintenance. For China's rapidly expanding carbon fiber sector, the immediate value of standardization lies in reducing the marginal cost of replicating and scaling up production lines.
Practical Impact on the Supply Chain
The most direct beneficiaries of the new standard are equipment procurement teams. Previously, carbon fiber companies had to spend considerable time on technical benchmarking and compatibility testing when purchasing precursor equipment, as parameters from different suppliers were difficult to compare directly. After the standard takes effect, the unified classification and model numbering rules will enable buyers to conduct more efficient price and performance comparisons. On a deeper level, the standard provides technical endorsement for domestic equipment substitution. In the past, downstream companies often preferred imported equipment partly because domestic products lacked a unified quality benchmark. The national standard helps create a level playing field among domestic suppliers, pushing domestic precursor equipment from 'usable' to 'reliable'.
Targeting High-Performance and Large-Tow Solutions
Setting the standard is just the beginning. Jinggong Technology has announced plans to promote the application of industry group standards alongside the two national standards, focusing on overcoming bottlenecks in large-tow, high-performance PAN precursor and carbonization equipment. Global carbon fiber demand is increasingly shifting toward large-tow products, which offer cost advantages in industrial applications such as wind turbine blades and pressure vessels. However, large-tow precursor production places higher demands on equipment uniformity and stability. The establishment of a standard system provides a quantifiable reference for these technical challenges, helping to shorten the transition from laboratory to mass production.
