For digital batteries, energy storage batteries and electric bicycle batteries to be sold in domestic and overseas markets, battery certification is an indispensable compliance step. Many manufacturing enterprises tend to confuse various test reports and equate transportation reports with market access qualifications. They only discover compliance loopholes when the goods arrive at the port and are detained or removed from the platform.
In actual business operations, the regulatory rules for batteries vary greatly among different countries and regions. Transportation safety, market access, and platform reviews fall under different systems, and a single report cannot cover all scenarios. Many small and medium-sized enterprises lack full-time compliance personnel and fail to receive standard updates in a timely manner, which can easily lead to project delays and economic losses. Shenzhen Chengce Testing, as a comprehensive third-party testing and certification institution, has a 3,000-square-meter supporting laboratory. It provides full-process technical services for categories such as button batteries, energy storage, and electric bicycle batteries, helping enterprises clarify the battery certification requirements of different markets and avoid compliance risks in advance.

The mainstream battery certification categories should be clearly distinguished between transportation and market access

Transportation test: UN38.3
UN38.3 is an internationally recognized transportation safety test. Whether it is for lithium batteries by air or sea, this report serves as the fundamental document for logistics booking. The test simulates extreme working conditions such as high-altitude low-pressure, temperature cycling, vibration and shock, short circuit, and overcharging to verify that the battery will not catch fire or explode during transportation. It should be noted that UN38.3 only addresses the transportation link and cannot replace the market access certification of various countries. If the product is to be sold locally, it still needs to complete the compliance project of the corresponding region.

Overseas market access certification
Different sales regions have independent mandatory requirements: the EU requires CE certification, South Korea implements KC certification, Japan requires PSE certification, the North American market commonly uses UL-related tests, Russia and the Eurasian Economic Union require EAC certification, and India's BIS and Taiwan's BSMI also set control rules for batteries. The requirements for different categories also vary. The standard provisions for consumer digital batteries, energy storage batteries, and batteries for electric two-wheelers are significantly different, and reports cannot be directly applied to each other.

Domestic compliance project
For battery products sold in the domestic market, it is necessary to pay attention to CCC certification and relevant standards of GB31241, do a good job in safety regulations testing and data archiving, and meet domestic regulatory requirements.

Common misunderstandings in the battery certification industry for enterprises

Misconception One: One report dominates the entire market
Some enterprises, upon obtaining the UN38.3 report, believe that they can directly sell their products globally. Transportation testing does not equal sales access. CE is still required for exports to the European Union, and KC is needed for sales to South Korea. The purposes, items and review subjects of the two types of tests are completely different and cannot replace each other.
Misconception 2: Directly applying the battery cell report to the finished battery pack
Many manufacturers only provide test reports for the battery cells, and the finished battery packs do not undergo corresponding tests. When the platform and customs conduct reviews, they will require that both the battery cell and battery pack reports be complete. If only the battery cell report fails to pass the review, this is also a common reason for the rejection of foreign trade shipments.
Misconception 3: Continuing to use the old report after a product update
Changes in battery capacity, protection board solutions, and battery cell suppliers all fall under product design alterations, and the original battery certification reports are no longer applicable. After many enterprises make minor reforms, they do not update the tests. As a result, when they encounter random tests later, the problem of certificate invalidation will occur.
Mistake Four: Ignoring the update of regulations
Battery-related regulations overseas have been constantly evolving. For instance, the new battery regulations of the European Union have added requirements such as carbon footprint and battery replaceability. Some Southeast Asian countries are also updating their battery control lists. If the old standard reports are always used, even if the customs can be cleared that year, compliance will become invalid after the new regulations are implemented.

Practical suggestions for enterprises to carry out battery certification

In the early stage, sort out the target market: First, determine which countries the product is mainly sold to, distinguish the transportation requirements and sales access requirements, list the certifications that need to be completed clearly, avoid repeated testing, and reasonably control the cycle and cost.
Distinguish between battery cells and finished products: Evaluate battery cells and battery packs separately to confirm the model and parameter range covered by the report. Do not borrow reports across specifications.
Reserve sufficient testing period: Battery testing involves sample testing, document review, and factory inspection guidance. Complex projects have a long cycle. Try not to start the certification work just before shipment.
Follow up on standard developments: Continuously monitor the regulatory updates in the target market. When there are revisions or iterations, simultaneously assess whether the existing reports remain valid.

Emphasize the authenticity and validity of reports: Give priority to third-party laboratories with corresponding capabilities, and reject invalid and duplicate reports to prevent them from becoming invalid during customs and cross-border platform verifications.

At the end
Overall, battery certification is an important foundation for the circulation of battery products in both domestic and international markets. Enterprises should not simply understand certification as merely obtaining a paper report. They need to clearly distinguish the boundary between transportation safety and market access, match the standards of corresponding countries and product categories, and plan the testing cycle in advance. Only in this way can they reduce risks such as customs detention and product removal, and ensure that their products smoothly open up sales channels both at home and abroad.
