What does UN38.3 certification mean for the ETENWOLF C2 tire pump?

UN38.3 is the internationally recognized test standard for lithium batteries transported by air, defined in the UN Manual of Tests and Criteria, Part III, Sub-section 38.3. For the ETENWOLF C2, it confirms that the built-in 2S1P-2000 7.4V 2000mAh 14.8Wh lithium-ion battery pack has passed all eight mandatory tests — altitude simulation, thermal, vibration, shock, external short circuit, impact/crush, overcharge, and forced discharge — and is safe for air transport when properly packaged.

Can the ETENWOLF C2 be shipped on passenger aircraft?

Yes. Report PEKSZ202509296600LTT120001 confirms the ETENWOLF C2 qualifies for transport on both passenger and cargo aircraft under IATA DGR Packing Instruction 967, Section II. The battery's 14.8Wh rating is well below the 100Wh per battery and 20Wh per cell thresholds. Batteries must be protected against short circuits and the device must have a means of preventing accidental activation.

Who issued this UN38.3 report and is it still valid?

The report was issued by Beijing DGM Air Transport Technology Development Co., Ltd. (DGM China) on 2025-10-16, with report number PEKSZ202509296600LTT120001. It is valid for the duration of the IATA DGR 66th Edition (2025 calendar year). The underlying UN38.3 battery tests were conducted by Waltek Testing Group Co., Ltd. in Dongguan, Guangdong, China.

What packaging and labeling is required when shipping the ETENWOLF C2 by air?

Each package must display the required lithium battery mark per IATA DGR PI 967, Section II requirements. Batteries must be protected to prevent short circuits, and the equipment must incorporate an effective means of preventing accidental activation. The shipper must ensure the goods match exactly what was assessed in report PEKSZ202509296600LTT120001.
