SELO China Certification for Pressure Vessels & Special Equipment
For global manufacturers of pressure equipment such as pressure vessels, boilers, or safety accessories, entering the Chinese market requires mandatory approval through the SELO China system. The Special Equipment Licensing Office (SELO) under the State Administration for Market Regulation (SAMR) oversees this licensing framework, which is a core part of China’s national safety regulations for special equipment.
A valid SELO license certifies that the product complies with the Special Equipment Technical Standards (TSG), the Guobiao Standards (GB), and national market regulation requirements. Without the appropriate license, manufacturers may face customs rejection, operational blocks, or denial of product installation in China.
Regulatory Framework for SELO Certification
The SELO certification scheme is based on China’s Regulations on Safety Supervision of Special Equipment, which provide the legal basis for managing special equipment such as gas cylinders, steam boilers, and pressure vessels. The following are key regulations:
These standards and regulations define the basic requirements, technical scope, and licensing process for all products subject to SELO oversight. They also ensure quality assurance and consistent production standards.
Scope of the SELO License
A SELO license is required for a wide range of special equipment, including:
All equipment falling within the SELO China regulatory scope must be approved through the equipment licensing office SELO before it can be sold, installed, or operated in China.
The SELO Licensing Process
Step 1: Application Process
Cisema ensures complete and correct submission throughout the approval procedure, reducing the risk of rejection.

Step 2: Design Appraisal (If Required)
Some pressure equipment requires a Design Appraisal Conformity Certificate from a designated research institute in China, especially pressure vessels or products not previously certified under SELO China.
Step 3: On-Site Inspection
Cisema prepares your team for this inspection with friendly audits, mock reviews, and real-time support during the visit. This is especially helpful for first-time applicants or those managing an alteration to an existing license.

Step 4: Issuance of the SELO License
Once the audit and testing are successful, the license is issued. The SELO license is typically valid for four years, subject to regular inspection and annual surveillance audits.
The product is now eligible for the China Stamp, a critical mark of compliance required to sell, install, or operate special equipment in China.
Importance of the SELO License in the Chinese Market
The SELO license is more than a technical approval—it's a market passport. Without it, your pressure vessels, safety valves, and other special equipment cannot clear Chinese customs or be used in projects within the country.
The license also builds trust with local regulators, clients, and project stakeholders by proving your product meets Chinese regulation and compliance standards under the GB standards and TSG framework.
