CSPC PERIC Specialty Gases (Shanghai) Co., Ltd. is a joint venture established by China Shipbuilding System Engineering Research Institute, a subsidiary of China State Shipbuilding Corporation Limited, and Hebei Pari Special Gases Co., Ltd. (listed on the Beijing Stock Exchange, stock code: 831175). The State-owned Assets Supervision and Administration Commission of the State Council is the actual controller. The company is positioned as one of the core domestic platforms for electronic specialty gases targeting strategic emerging industries, including semiconductors, display panels, LEDs, photovoltaics, and high-end manufacturing.  

The company focuses on research and development, production, filling, testing, transportation, and on-site services for high-purity, high-stability, and high-safety electronic specialty gases. Its principal products include over ten types of electronic specialty gases, such as nitrogen trifluoride (NF₃), tungsten hexafluoride (WF₆), carbon tetrafluoride (CF₄), octafluorocyclobutane (c-C₄F₈), high-purity ammonia (NH₃), and silane (SiH₄). NF₃ and WF₆ have already achieved mass supply to 12-inch logic and memory chip production lines and have passed multiple rounds of process validation at leading domestic wafer fabs—including Semiconductor Manufacturing International Corporation (SMIC), Yangtze Memory Technologies Co., Ltd. (YMTC), and CXMT—entering their qualified supplier lists.  

The company operates an electronics-grade gas filling and analytical laboratory compliant with SEMI F57 standards, capable of impurity detection at the parts-per-trillion (ppt) level. It holds certifications for three major management systems—ISO 9001, ISO 14001, and ISO 45001—as well as key licenses, including the Hazardous Chemicals Business License, Road Transportation License for Hazardous Goods, and Special Equipment Production License (for pressure vessel filling). Leveraging the large-scale production capacity of Pari’s Handan base (annual NF₃ output exceeding 5,000 metric tons and annual WF₆ output exceeding 300 metric tons) and Shanghai Lingang’s R&D and application service center, the company has established an integrated layout covering “R&D–pilot production–mass production–localized service,” providing deep support to the Yangtze River Delta integrated circuit industry cluster.  

The company undertakes key projects under Shanghai’s “14th Five-Year Plan” for strengthening and supplementing the integrated circuit industrial chain, as well as sub-projects under the Ministry of Industry and Information Technology’s Industrial Foundation Reconstruction Project. It has led or participated in drafting three national standards and two industry standards, and holds 12 authorized invention patents and eight utility model patents. Currently, its business is concentrated exclusively in the mainland China market, with cooperation areas spanning electronic specialty gas supply, process compatibility support, on-site technical services, joint R&D, and collaborative standard development.
