GMA International Certification Capabilities

The UN38.3 test report is a mandatory document for air transportation of products and a foundation for many international certifications. Our test reports and data can support your products in entering the following markets (including but not limited to):

• European Economic Area (CE Marking): Battery Directive, EMC Directive, etc.
• North America (USA/Canada): Battery products complying with FCC, ISED, and other regulatory requirements.
• United Kingdom (UKCA Marking): Market access requirements after the UK’s withdrawal from the EU.
• Asia-Pacific Region: Battery safety components in certifications such as China CQC, Japan PSE, South Korea KC, and Australia RCM.
• Other Regions: Over 130 countries and regions including the Middle East (e.g., GCC), ASEAN, and South America (Data source: ESTL internal statistics).

Important Note: Market access requirements are complex and dynamically changing; the above information is a general overview. The final certification plan shall be subject to the specific product model and the latest requirements of the official authorities in the target country/region.

Service Process and Factors Affecting Cycle

Our typical service process is designed for clarity and transparency:

Factors Affecting Cycle:

• Sample Preparation: Quantity of samples and completeness of documents.
• Test Results: Whether the test passes on the first attempt or requires rectification and re-testing.
• Project Complexity: Battery type and special requirements of testing standards.
• Official Authority Processes: If report review or submission to a third-party certification body is involved, the cycle is subject to the actual progress of the authority.

Cases and Practices

• Case 1: A domestic sodium-ion battery pack manufacturer needed to export products to the EU. We assisted them in completing full UN38.3 testing and provided a compliant test summary report, successfully resolving air transportation compliance issues.
• Case 2: An electric two-wheeler enterprise whose vehicles are equipped with sodium-ion batteries. We conducted UN38.3 testing on their battery modules and provided compliant documents to support the transportation of the entire vehicle.

Frequently Asked Questions (FAQ)

1. Q: How many samples are needed for UN38.3 certification?
   A: The number of samples depends on the battery type (cell/battery pack) and specific testing items. Typically, 25–30 cells or 15–20 battery packs are required. The final quantity shall be confirmed before the project starts based on standard requirements and laboratory recommendations.

2. Q: Will UN38.3 test reports issued by ESTL be accepted by airlines or foreign clients?
   A: Our laboratory holds qualifications such as CNAS; our testing processes and report formats meet international general requirements and are widely recognized by airlines, freight forwarders, and buyers worldwide. If there are special requirements from specific clients or carriers, we recommend communicating in advance.

3. Q: What is the approximate cycle and cost for UN38.3 testing?
   A: The cycle is usually 2–3 weeks (counted from the receipt of samples, advance payment, and if no rectification is needed for samples). The cost varies based on battery type, capacity, voltage, and testing items. Please contact us with your product specification sheet to obtain an accurate quote.

4. Q: What if the test fails?
   A: We will provide a detailed test failure report and, based on our technical experience, offer potential cause analysis and improvement suggestions (if needed). Clients can rectify the issues and resubmit samples for supplementary testing.

5. Q: What is the relationship between UN38.3, IEC 62133, and CB certification?
   A: UN38.3 is a mandatory test for transportation safety; IEC 62133 is a safety standard for battery products themselves; the CB Scheme is an international mutual recognition system based on IEC standards. They serve different purposes but may share some test data in some cases. Your product may need to meet multiple requirements simultaneously.

6. Q: How to choose a reliable UN38.3 testing institution?
   A: It is recommended to prioritize institutions with CNAS qualifications, whose laboratory capabilities cover UN38.3-related standards, have rich industry experience, and transparent service processes. You can request qualification certificates from the institution and verify their authenticity.

7. Q: Does your service include consultation and rectification support?
   A: Yes. In the early stage of the project, we provide necessary standard consultation. If the test fails, our engineering team will offer technical rectification suggestions and support to help you analyze the root cause of the problem.
