A buyer sourcing e-bike or scooter batteries from China often assumes every lead-acid battery ships as Class 8 dangerous goods, which means extra freight surcharges, DG paperwork, and slower port clearance on every order. For two specific Tianneng valve-regulated models built for two-wheeler use, third-party test data tells a different story: these batteries have been tested and confirmed as non-restricted cargo, not subject to the IMDG Code.
Why E-Bike and Scooter Batteries Get Flagged as Dangerous Goods
Lead-acid batteries fall under UN Class 8 (Corrosive). Whether a specific battery actually ships under full dangerous goods rules depends on its construction. A wet, filled battery (UN2794) has free liquid electrolyte that can spill if the case is damaged, so it is treated as fully regulated dangerous goods for sea and air freight.
A valve-regulated lead-acid (VRLA) battery — including AGM and gel designs — holds its electrolyte in an absorbed mat or gel rather than as free liquid (UN2800). If a specific model passes the required vibration, pressure differential, and 55℃ leakage tests under UN Model Regulations Special Provision 238, it qualifies as non-restricted cargo under IMDG Special Provision 238 for sea freight and IATA Special Provision A67 for air freight. The exemption is issued per tested model, not per brand.
The Test Evidence: 6-DZF-20.3 and 6-DZF-22.3
CANEN ELEC has on file two CNAS-accredited third-party test reports from Shanghai Institute of Chemical Industry Testing Co., Ltd. (SICIT), covering the following Tianneng valve-regulated gel batteries built for electric bicycle and scooter use:
- 6-DZF-20.3 (12V 20.3Ah) — Report No. 222600423855970, tested to the IMO IMDG Code (2024 Edition), issued December 25, 2025, effective January 1, 2026. Vibration test, pressure differential test, and 55℃ leakage test all passed. Conclusion: non-restricted goods, not subject to IMDG Code per Special Provision 238.
- 6-DZF-22.3 (12V 22.3Ah) — Report No. 222500909088430, tested to the IMO IMDG Code (2022 Edition), issued December 22, 2024, effective January 1, 2025. Vibration test, pressure differential test, and 55℃ leakage test all passed. Conclusion: non-restricted goods, not subject to IMDG Code per Special Provision 238.
Both reports are issued to Tianneng Battery Group Co., Ltd. as manufacturer. Tianneng’s own material safety data sheet for its non-spillable VRLA range separately confirms the same Special Provision 238 (IMDG), Special Provision A67 (IATA), and DOT 49 CFR 173.159(d) exemption framework for models that pass this testing.
What This Means for Your Order
If your order matches the 6-DZF-20.3 or 6-DZF-22.3 model and capacity exactly, you can expect standard general-cargo freight quotes rather than dangerous goods surcharges, no DG shipping paperwork or hazard placarding requirement for these units, and fewer port-side compliance checks. CANEN ELEC can provide the matching test report copy for your freight forwarder or customs broker on request.
What This Exemption Does Not Cover
The test reports are model-specific, and buyers should not extend the conclusion beyond what they actually cover:
- Chilwee-brand batteries are not covered. Both reports above are for Tianneng-manufactured cells only.
- Forklift and pallet truck batteries are not covered. Motive power batteries for forklifts and pallet trucks are a different product category from e-bike and scooter batteries, and generally continue to ship as UN2794 Class 8 regulated dangerous goods unless a matching non-spillable test report exists for that specific model.
- Other Tianneng models are not automatically covered. A model outside this tested range needs its own matching report before it can be shipped or labeled as non-restricted cargo.
For background on how the UN2794/UN2800 distinction affects starting and stationary/energy storage battery shipments generally, see our earlier article on VRLA vs Flooded Lead-Acid Batteries.
Are all Tianneng e-bike batteries automatically non-restricted cargo?
No. Only models with a matching third-party test report on file — currently the 6-DZF-20.3 and 6-DZF-22.3 — are confirmed as non-restricted cargo. A different model or capacity needs its own report before the same conclusion applies.
What tests does a battery need to pass for this exemption?
Under UN Model Regulations Special Provision 238, a non-spillable battery must pass a vibration test, a pressure differential test, and a leakage test at 55℃ with no electrolyte flow from a ruptured or cracked case. IATA Special Provision A67 uses the same test criteria for air freight.
Does this exemption cover Chilwee-brand e-bike batteries?
No. The test reports CANEN ELEC currently holds are for Tianneng-manufactured 6-DZF-20.3 and 6-DZF-22.3 cells only. Chilwee e-bike batteries are not covered by these reports.
Do forklift or pallet truck batteries qualify for the same exemption?
Generally no. Forklift and pallet truck motive power batteries are a different product line from e-bike and scooter batteries and typically ship as UN2794 Class 8 dangerous goods, unless a separate non-spillable test report exists for that specific model.
