The CB Scheme (Certification Body Scheme) is an international system operated by IECEE (IEC System for Conformity Assessment Schemes for Electrotechnical Equipment and Components) that facilitates global trade through mutual acceptance of test reports and certificates for electrical products. For power bank manufacturers and exporters in Southeast Asia looking to sell on Alibaba.com, understanding this system is crucial for accessing international markets efficiently.
The core philosophy behind CB Scheme is "one product, one test, one mark" — a concept designed to reduce redundant testing, lower compliance costs, and accelerate time to market for electrical products including portable power banks and battery packs. When you list CB certified products on Alibaba.com, you signal to global buyers that your products meet internationally recognized safety standards.
For rechargeable batteries and power banks specifically, the CB Scheme applies IEC 62133-1 (for nickel-based cells) and IEC 62133-2 (for lithium-based cells) standards. These standards cover safety requirements for portable sealed secondary cells and batteries used in portable applications. The harmonization of these standards across participating countries means that a CB Test Report and CB Test Certificate issued by one IECEE member body can be accepted by certification bodies in other member countries [2].
The CB Scheme provides a simplified way to obtain multiple national safety certifications based on a single set of test results. This reduces costs and accelerates time to market for manufacturers targeting global distribution [2].
From a practical standpoint for Alibaba.com sellers, CB certification offers several strategic advantages: it demonstrates commitment to international quality standards, reduces barriers when expanding to new markets, and provides a foundation for obtaining regional certifications (like CE for Europe, UL for North America, or CCC for China) with reduced additional testing. However, it's important to understand that CB certification alone may not be sufficient for all markets — some countries require their own national marks in addition to or instead of CB.
CB Scheme Certification Process Overview
| Step | Activity | Typical Timeline | Key Output |
|---|---|---|---|
| 1 | Application Submission | 1-2 weeks | Application documents, product samples |
| 2 | Testing at CB Testing Laboratory | 3-4 weeks | Test reports per IEC 62133 standards |
| 3 | Certification Body Review | 1-2 weeks | CB Test Certificate and CB Test Report |
| 4 | National Certification Conversion | 2-4 weeks per country | National marks (CE, UL, CCC, etc.) |
