China’s State Administration for Market Regulation (SAMR) has announced the implementation of China Compulsory Certification Requirements for gas appliance connecting hoses and gas emergency shut-off valves.
Effective from October 1, 2025, all hoses for connecting gas appliances and gas emergency shut-off valves listed in the CCC certification catalogue must be certified by CCC and bear the CCC certification marks before they can be manufactured, sold, imported, or used in business activities. Starting from October 1, 2024, designated certification bodies will begin accepting CCC certification commissions.
These certification bodies are required to formulate implementation rules for certification based on the general CCC certification rules and the “Rules for the Implementation of Compulsory Product Certification for Gas Burning Appliance Safety” (Annex 2 of the recent announcement – summary provided below).
To alleviate the burden on enterprises, the designated certification bodies and laboratories are encouraged to utilize existing conformity assessment results where possible, ensuring that certification risks remain controlled and certification quality is upheld.
Annex 2 Overview: Certification Process for Safety Accessories used in Gas-Burning Appliances
Annex 2 of the document, labeled CNCA-C24-02:2024, outlines the compulsory certification process for safety accessories used in gas-burning appliances. This certification process has significant implications for manufacturers of these products, including hoses for gas appliance connections and solenoid gas emergency shut-off valves. The document details the rigorous standards and procedures manufacturers must adhere to in order to comply with certification requirements, which are designed to ensure product safety and quality. Failure to meet these standards can prevent manufacturers from entering or remaining competitive in the Chinese market.
Scope and Impact on Manufacturers
The scope of the China Compulsory Certification Requirements for gas appliance connection hoses and solenoid gas emergency shut-off valves used in residential and commercial settings. The scope of application for this rule covers two main categories of products:
- Hoses for connecting gas appliances: These include stainless steel corrugated hoses with specific size and pressure limits, designed for town gas, gas combustion appliances, and connections from bottled liquefied petroleum.
- Solenoid gas emergency shut-off valves: These are used in gas pipelines (natural gas, liquefied petroleum gas, artificial gas) and are linked to urban gas safety control systems.
The certification process is divided into several critical stages, including product inspection, initial factory inspection, and post-certification supervision. Each stage involves detailed procedures that manufacturers must follow:
- Product Testing: Manufacturers must submit their products for rigorous testing to verify that they meet the specified safety and performance standards. This testing is typically conducted in designated laboratories and includes various tests such as pressure resistance, tensile strength, and durability (see below for more details). The process ensures that the product is safe for consumer use and capable of withstanding the conditions it will be exposed to during its operational life. By complying with these inspection requirements, manufacturers can enhance their product’s marketability and consumer trust.
- Initial Factory Inspection: After product testing, manufacturers undergo an initial factory inspection. This inspection evaluates the manufacturer’s production processes, quality assurance systems, and consistency in product manufacturing. The inspection is comprehensive, covering all production sites involved in the manufacturing process. For manufacturers, this means maintaining high standards in their production processes to pass the inspection and achieve certification. Successfully passing this stage can open doors to broader market access and improve operational credibility.
- Post-Certification Supervision: Once a product is certified, manufacturers are subject to ongoing supervision. This includes follow-up inspections, sampling of products from production lines, and market sampling to ensure that products continue to meet certification standards. Manufacturers must maintain detailed records and be prepared for unannounced inspections, which can occur at any time during the certification period.
Division of Certification Units
The certification process also involves the division of products into certification units based on various factors such as product type, connection characteristics, and installation environment. This division ensures that each product variant is appropriately tested and certified, but it also increases the complexity and cost for manufacturers, especially those producing a wide range of products.
Impact of Compliance and Certification Changes
The certification process impacts manufacturers significantly in terms of compliance costs, operational adjustments, and product design modifications. Manufacturers must invest in high-quality materials, maintain stringent production standards, and possibly redesign products to meet certification requirements. Additionally, any changes to certified products, such as modifications to key components or changes in the manufacturing process, require re-evaluation and potentially new certification, further adding to the manufacturer’s burden.
Penalties for Non-Compliance
Failure to comply with these certification requirements can result in severe consequences for manufacturers, including the suspension or revocation of certification. This not only affects the ability to sell products in the market but can also lead to significant financial losses and damage to the manufacturer’s reputation.
