With the surging demand for outdoor camping and emergency backup power, portable energy storage power supplies have become a hit product in the global consumer electronics market. However, the lithium batteries that serve as their core power source pose certain safety risks during air transport. Therefore, UN38.3 Certification has become a mandatory "safety ID" and "pass" for all energy storage power products to cross borders and enter the global market.

I. What Is UN38.3 Certification?

UN38.3 Certification is not an ordinary voluntary certification; it is an international standard formulated based on Chapter 38.3 of the UN Recommendations on the Transport of Dangerous Goods – Manual of Tests and Criteria. This standard specifically conducts mandatory assessments on the safety of lithium batteries during transportation, ensuring that lithium batteries are stable and safe under normal transport conditions.

In simple terms, any device containing lithium batteries (including energy storage power supplies) must obtain UN38.3 Certification if it is to be transported by air, sea, land, or other means. Otherwise, it will be refused carriage by all transportation agencies.

II. Why Must Portable Energy Storage Power Supplies Obtain UN38.3 Certification?

1. Mandatory Regulatory Requirements

Major global airlines and shipping organizations, such as the International Air Transport Association (IATA) and the International Maritime Organization (IMO), all take UN38.3 Certification as a prerequisite for accepting lithium battery shipments. Without this certification, your products will be unable to move forward in the global supply chain.

2. Ensuring Transport Safety

Portable energy storage power supplies usually use large-capacity lithium-ion battery packs, which may face challenges such as collisions, 挤压 (crushing), and temperature-humidity changes in complex transport environments. Through a series of rigorous simulation tests, UN38.3 Certification fundamentally prevents safety accidents such as combustion and explosion caused by battery issues.

3. Market Access Threshold

Whether exporting to Europe, the United States, Southeast Asia, Japan, South Korea, or other markets, UN38.3 is an essential document for customs clearance and entry into mainstream sales channels. It is the most basic and authoritative evidence to prove the safety of your products to customers and partners.

4. Enhancing Brand Reputation

Proactively conducting and passing UN38.3 Certification reflects the manufacturer’s high sense of responsibility for product safety. It can significantly enhance the confidence of consumers and purchasers, and improve brand image and market competitiveness.

III. What Are the Main Test Items of UN38.3 Certification?

UN38.3 Certification includes 8 rigorous tests, comprehensively simulating potential hazards during transportation:

1. Altitude Simulation Test: Simulates safety under low-pressure air transport conditions.
2. Thermal Test: Examines the stability of the battery under rapid and extreme temperature changes.
3. Vibration Test: Simulates frequent vibrations during transportation.
4. Impact Test: Simulates possible collisions and impacts during transportation.
5. External Short Circuit Test: Inspects the battery’s protection capability when an external short circuit occurs.
6. Crush Test: Evaluates the safety of the battery when subjected to significant mechanical force.
7. Overcharge Test: Verifies the protection function of the Battery Management System (BMS) under overcharging conditions.
8. Forced Discharge Test: Assesses the safety of battery cells under forced discharge conditions.

Note: Portable energy storage power supplies are usually certified as "battery packs" or "batteries packed with equipment," with more comprehensive testing requirements.
