On September 17, a collaborative event took place as Jiulongpo District in Chongqing joined forces with Xindu District in Chengdu to host the fourth "Xinlong" Quality Innovation Achievement Presentation and Quality Cooperation Exchange Activity. During this gathering, the two regions jointly released the first compliance guidelines for hydrogen energy quality infrastructure across the Chengdu-Chongqing economic zone, addressing a previous gap in quality standards for the regional hydrogen industry and charting a clear compliance pathway for its large-scale, standardized growth.

The event was co-organized by the Jiulongpo District Government of Chongqing and the Xindu District Government of Chengdu, with execution handled by the market supervision administrations of both districts. It drew participation from industrial parks and over a hundred supply chain enterprises from the two regions.

The program featured a showcase of high-caliber quality innovation achievements, exchanges on frontline Quality Control (QC) improvement cases, and a patent navigation analysis for the hydrogen sector. These initiatives tackled aspects such as technology, processes, standards, and intellectual property, contributing to cost reduction and efficiency gains in the advanced manufacturing and hydrogen industries throughout the Chengdu-Chongqing zone.
