12 Documents You Need
Exporting LiFePO4 batteries requires more paperwork than ordinary goods. Missing documents cause the most common delays. Here’s the complete checklist:
| # | Document | Issued By | Key Point |
|---|---|---|---|
| 1 | Commercial Invoice | Exporter | Must match packing list and B/L exactly |
| 2 | Packing List | Exporter | Weights must match actual cargo |
| 3 | MSDS/SDS | Manufacturer | Update annually; model must match shipment |
| 4 | UN38.3 Test Report | CNAS-accredited lab | No fixed expiry unless standard revises |
| 5 | UN38.3 Test Summary | Lab | Mandatory since 2020; many suppliers lack this |
| 6 | Sea Transport Appraisal | Inspection institute | Typically expires Dec 31 each year |
| 7 | DG Packaging Certificate | CIQ | Proves packaging meets Class II standards |
| 8 | Certificate of Origin | CCPIT/Customs | For tariff preferences (RCEP etc.) |
| 9 | Customs Declaration | Broker | HS 8507.60 — verify classification |
| 10 | Dangerous Goods Declaration | Forwarder | Never under-declare; see penalties below |
| 11 | Container Packing Certificate | Packing party | Required for FCL dangerous goods |
| 12 | Bill of Lading | Carrier | Title document for cargo release |
UN38.3 Testing Explained
UN38.3 (UN Manual of Tests and Criteria, Part III, 38.3) is mandatory for all lithium battery transport. Eight tests:
- T1 Altitude: Low pressure simulation, check for leakage
- T2 Thermal: -40°C to +72°C cycling
- T3 Vibration: Transport vibration simulation
- T4 Shock: Impact resistance
- T5 External short circuit: At 57°C, case temp must stay below 170°C
- T6 Crush/Impact: Cell-level mechanical abuse
- T7 Overcharge: 24-hour overcharge at 2x current (pack level)
- T8 Forced discharge: Cell-level reverse polarity
Practical notes: Testing takes about 3 weeks in China and costs from ~$2,000 (industry estimates). The report has no fixed expiry unless the UN standard is revised — unlike MSDS and transport appraisals which typically expire annually. Since 2020, a Test Summary (abbreviated version) must be available on request; many suppliers don’t have this ready, causing booking delays.
How to Spot Fake Test Reports
- Verify the lab has CNAS accreditation
- Check the model number matches your exact shipment
- Confirm a Test Summary exists alongside the full report
- Check the UN standard version referenced is current
- When in doubt, contact the lab directly to verify
Dangerous Goods Shipping (IMDG)
LiFePO4 batteries are Class 9 dangerous goods:
- UN3480: Lithium ion batteries shipped alone
- UN3481: Batteries packed with or contained in equipment
- Packaging: Must meet Packing Group II standards (P903)
- Labeling: Class 9 diamond + lithium battery mark
Important correction: The 30% state-of-charge limit is an IATA air freight rule. IMDG sea freight has no universal SOC requirement — a common industry misconception. For the deeper UN3480 vs UN3481 sea checklist, P903 notes and forwarder document pack, see our LiFePO4 sea freight UN3480/UN3481 IMDG guide.
Key Market Requirements
- USA: UL 1973/9540 for stationary storage; FCC for wireless BMS. Duty on China-origin lithium-ion batteries (HTS 8507.60.00; statistical suffix .0030 for fully encased battery energy storage systems, .0090 for other): 3.4% general duty + 25% Section 301 (heading 9903.91.06, from 1 January 2026; 89 FR 76581) + 12.5% Section 301 forced-labor action (heading 9903.05.31, from 24 July 2026; 91 FR 47318) = 40.9% on transaction value, as of 29 October 2026. IEEPA tariffs (struck down by the Supreme Court on 20 February 2026) and the Section 122 surcharge (expired 24 July 2026) no longer apply. Fees such as MPF and HMF are extra; confirm the total with your broker. See our USA import duty and compliance guide.
- Canada: 7% MFN duty (tariff item 8507.60.90) + 5% GST; TDG rules for UN3480. See our Canada import guide.

Logistics Timeline
Plan for 10–12 weeks total:
- Order confirmed → Request UN38.3 + Test Summary (if missing, add 3 weeks)
- Production → Update transport appraisal, MSDS
- 2 weeks before shipment → DG packaging certificate, book DG container (10–14 days advance needed)
- 1 week before → Maritime dangerous goods declaration
- Loading → Container packing certificate, DGD
- Customs clearance → Declaration, inspection if required
- After sailing → B/L, Certificate of Origin sent to buyer
Real Penalties for Non-Compliance
- FAA $260,000 fine (2026): Company shipped undeclared batteries via UPS; package smoked at sorting facility. Violations: undeclared DG + SOC exceeded + no documentation.
- FAA $160,500: 30 batteries shipped undeclared from Hong Kong.
- X-Press Godavari fire (2020): lithium-ion batteries shipped under IMDG special provision 188, so the container was not declared as dangerous goods; the probable cause was a battery short circuit, and the fire was still not fully out 24 hours after smoke was seen (Transport Malta MSIU report).
Never misdeclare lithium batteries. Penalties far exceed any freight savings.
Frequently Asked Questions
How long does UN38.3 testing take?
About 3 weeks including report issuance (industry estimate for China labs).
Can I use last year’s transport appraisal?
No. These typically expire December 31 each year and must be renewed.
What’s the difference between UN3480 and UN3481?
UN3480 is batteries shipped alone. UN3481 is batteries packed with equipment or contained in equipment. Different packing instructions apply.
