When planning to launch products such as batteries, power banks, or energy storage batteries into the international market, CB certification is undoubtedly a core link you cannot bypass. As an international mutual recognition system connecting more than 50 countries and regions worldwide, it is regarded as the "international passport" for product safety compliance. One of the top concerns for many enterprises during planning is: "How much does CB certification cost?" The answer is not a fixed figure, but an efficient investment that can be accurately planned based on product characteristics.

I. Core Components of CB Certification Costs

The total cost of CB certification mainly consists of several key components. For battery products, the core is the product testing fee, while others are fixed or optional administrative and service fees.

The table below clearly breaks down the main cost components and their approximate ranges:

Based on the above components, the total CB certification cost for a battery product is usually between RMB 10,000 – 30,000. For particularly complex energy storage battery systems, the cost may be higher.

II. Key Factors Affecting Battery Product Costs

Why is there such a wide cost range? The following factors are critical in determining the final cost:

1. Product Category & Applicable Standards

This is the primary factor influencing costs. Small lithium battery packs for consumer electronics are typically tested to IEC 62133, with relatively basic fees. In contrast, batteries for energy storage systems or industrial applications require compliance with standards such as IEC 62619, involving more test items and stricter requirements for battery management systems (BMS), leading to significantly higher fees.

2. Battery Capacity & Design Complexity

Under the same standard, products with larger capacity, more cells, or more complex circuit designs require more testing time and resources, resulting in higher testing fees.

3. Certification Scope & Series Models

If you wish to cover multiple models with one certification (series certification), the average cost per model decreases, but the initial total cost increases by approximately 30%-50% compared to a single model. "Differential fees" for adding new models later are also common expenses.

4. Target Markets & "National Deviations"

The value of CB certification lies in global mutual recognition, but countries may add special national requirements (i.e., "national deviations") based on IEC standards. Incorporating deviation testing for target countries (e.g., South Korea, Germany) during CB application incurs additional fees but avoids duplicate testing in the future, saving costs in the long run.

III. Professional Strategies to Optimize Certification Costs & Cycles

Treat CB certification as an investment—prudent planning can significantly improve its return on investment. We recommend enterprises adopt the following strategies:

Strategy 1: Choose an Efficient Path to Avoid Duplicate Investment

The most cost-effective strategy is to integrate CB certification planning into the mid-stage of product development. Our engineers can provide preliminary design reviews to identify and rectify potential compliance risks before product finalization. This is the most effective way to ensure "first-time pass" in testing and avoid costly modifications and retesting.

Strategy 2: Integrate Certification Needs to Achieve "One Test, Multiple Certifications"

If you plan to enter multiple international markets, the CB scheme is the cornerstone of "one test, multiple certifications." For example, a CB report including EU LVD directive deviations can be directly used to apply for the CE mark; similarly, it serves as an efficient foundation for converting to South Korea’s KC certification, Saudi Arabia’s GCC certification, etc., saving substantial time and money on duplicate testing.

Strategy 3: Leverage Professional Services for Accurate Cost Control & Efficiency

Experienced certification service providers can offer:

• Precise Pre-Evaluation & Quotation: Provide clear cost breakdowns based on detailed product information, eliminating hidden costs.
• Optimal Test Plan Planning: Help you balance the cost-effectiveness of series certification vs. single-model certification, and plan whether/when to include national deviation testing.
• Full-Process Project Management: We maintain close cooperation with multiple authoritative NCBs and laboratories, efficiently coordinating resources to shorten the standard 4-8 week certification cycle to an optimal level.

For battery products, CB certification costs are not a simple expense but a strategic investment to obtain international safety endorsement, break trade barriers, and quickly access global markets. The return on this investment—expanded market reach and enhanced brand reputation—far exceeds its cost.
