Cylindrical batteries, with their compact size and stable performance, are widely used in consumer electronics, smart home devices, outdoor equipment and other fields, and are indispensable energy cores in daily necessities and industrial products. The UN38.3 certification is precisely the key pass for this "Energy Cylinder" to safely go global and circulate in compliance.

Why must cylindrical batteries obtain UN38.3 certification?

UN38.3 is an internationally recognized safety standard for lithium battery transportation, with its core being to verify the safety of batteries during transportation. Without this certification, batteries cannot be circulated through mainstream transportation methods such as air and sea, and international orders simply cannot be fulfilled. At the same time, compliance certification can reduce safety risks during transportation and is also an important trust certificate for downstream customers when making purchases, avoiding returns or penalties due to non-compliance and clearing obstacles for products to enter domestic and international markets.

When applying for certification, all these materials must be prepared

1. Basic product information, including detailed descriptions of battery model, specification parameters, number of cells and connection methods, etc.

2. Product design drawings and technical specifications, clearly defining the structure and performance indicators of the battery.

3. Test samples (the quantity must meet the testing requirements), and ensure that the samples are consistent with the mass-produced products.

4. Relevant materials of enterprise qualifications, such as business licenses and other basic supporting documents.

The certification processing procedure is complete in one step without any pitfalls

1. Consultation and communication: Contact Zhongren Lianke, explain the product situation, and obtain the exclusive certification plan and quotation.

2. Submission of Materials: Organize and submit the relevant materials as required. We will quickly review their completeness.

3. Sample testing: Send the samples to the laboratory and complete a series of safety tests including high and low temperatures, vibration, and shock in accordance with the UN38.3 standard.

4. Report Review and Certification: After the test is passed, relevant data will be reviewed and a certification certificate will be issued. The entire process is efficient and transparent.
