Key Regulation 1: AQ 3063-2025 – Safety Management for Flammable Liquid Atmospheric Storage Tanks
Effective April 30, 2026, this comprehensive standard covers the entire lifecycle of atmospheric storage tanks containing flammable liquids:
Design requirements: Mandatory nitrogen blanketing, internal floating roofs, and leak detection systems for certain services.
Construction requirements: Stricter welding qualifications, NDT coverage, and hydrostatic test procedures.
Operational requirements: Detailed inspection intervals, maintenance records, and emergency response plans.
Retrofit deadlines: Existing single-wall underground tanks must be replaced or upgraded to double-containment systems within a defined transition period.
Key Regulation 2: VOC Emission Control Guidelines
China's Ministry of Ecology and Environment has issued updated guidelines requiring:
All volatile organic liquid storage tanks to be equipped with properly sized breather valves and vapor recovery systems.
Regular leak detection and repair (LDAR) programs for tank fittings and accessories.
Underground fuel storage tanks to use double-containment systems with continuous monitoring.
Key Regulation 3: Petrochemical Aging Equipment Replacement Program (2026–2029)
A seven-ministry joint plan encourages enterprises to accelerate the replacement of aging, corroded, or non-compliant storage tanks with modern, intelligent, and environmentally friendly alternatives. Financial subsidies and tax incentives are available in many provinces for qualifying upgrade projects.
How to Ensure Compliance
Facility owners planning new tank installations or retrofit projects should:
Work with manufacturers who hold ISO 9001, ISO 14001, and ISO 45001 certifications.
Request full compliance documentation including design calculations, material certificates, NDT reports, and test certificates.
Verify that tank designs specifically address the requirements of AQ 3063-2025 and applicable local regulations.
Zhongneng Huajian's entire product line-from SF double-wall fuel tanks to large vertical chemical storage tanks-is designed and manufactured to meet current national and industry standards. Full compliance documentation is provided with every delivery.
