The standardization of the carbon fiber supply chain is extending from the carbonization stage to the more upstream precursor machinery sector. A recently approved national standard is poised to fundamentally resolve the long-standing issues of chaotic terminology, inconsistent model numbering, and low coordination efficiency in domestic precursor equipment production, providing foundational support for the quality breakthrough of domestic carbon fiber.
Standard Fills a Critical Gap in Precursor Machinery
The State Administration for Market Regulation and the Standardization Administration of China have jointly approved and released the national standard 'Polyacrylonitrile Fiber Production Complete Equipment - Terminology, Classification, and Model Numbering Method'. Led by Zhejiang Jinggong Integrated Technology Co., Ltd. and Zhejiang Huachuang Carbon Fiber Technology Co., Ltd., this standard will take effect on February 1, 2027. It marks the first time China has a unified national technical specification for complete sets of carbon fiber precursor production equipment.
Previously, terminology definitions, equipment classifications, and model numbering for domestic precursor machinery varied widely among suppliers. This lack of uniformity resulted in significant communication costs and compatibility risks for end-users during line design, equipment selection, and procurement. The new standard directly addresses this industry pain point by establishing a common framework.
A Complete Equipment Standard System Takes Shape
This is not Jinggong Technology's first achievement in this area. Their previously led national standard for 'Fiber Carbonization Production Complete Equipment - Terminology, Classification, and Model Numbering Method' was already implemented in June 2025. Precursor and carbonization are the two core stages of carbon fiber production; the former determines the fiber's inherent quality, while the latter defines its final performance.
The successive implementation of these two standards means that from precursor preparation to carbonization treatment, the entire equipment chain now has unified terminology and classification rules. This provides clear design and production guidelines for equipment manufacturers and enables downstream carbon fiber producers to achieve more efficient cross-vendor coordination and equipment interchangeability during line planning, procurement, and future upgrades.
Industry Impact: The Logic of Cost Control and Quality Improvement
From an industry analysis perspective, the core value of standardization lies in reducing systemic friction costs. In the technology-intensive carbon fiber industry, the precision and intelligence level of precursor machinery directly determine the yield rate of precursor fibers, which in turn affects the cost and performance consistency of the final carbon fiber product. The previous lack of uniform standards meant that equipment parameters across different lines were difficult to compare directly, leading to lengthy process debugging cycles and inflated trial-and-error costs.
By unifying terminology and classification for the entire process—from polymerization, spinning, drawing, and drying to solvent recovery—this standard creates a common language for technical communication, equipment acceptance, and process replication across the supply chain. For domestic carbon fiber companies currently expanding capacity, this will help shorten the ramp-up time for new lines and reduce hidden losses caused by equipment mismatches.
Future Direction: Tackling Large-Tow and High-Performance Bottlenecks
Establishing the standard system is only the first step. Jinggong Technology has publicly stated that it will leverage the implementation of these two national standards to promote their application in group standards, while simultaneously focusing on overcoming core technical bottlenecks in large-tow, high-performance PAN precursor, and carbonization complete sets. This indicates that leading industry players are attempting to secure a strategic advantage and voice in the global competition for new materials by prioritizing standards.
For the domestic carbon fiber supply chain, unified equipment standards are a critical piece of infrastructure for enhancing the independent controllability of the entire industry. They provide quantifiable benchmarks for the substitution of imported equipment with domestic alternatives and offer a more stable quality guarantee for downstream applications such as aerospace, wind turbine blades, and hydrogen energy storage.
