Introduction
For many importers, sourcing the product is the easy part. The real headache begins when it’s time to ship.
Because rechargeable fans, lights, and searchlights contain Lithium-ion batteries, they are classified globally as “Dangerous Goods” (DG). If your supplier handles the paperwork incorrectly, you face customs seizures, massive fines, or weeks of delays at the port.
As a manufacturer exporting to over 60 countries, DP Light understands that logistics is part of the product quality. In this guide, we demystify the Class 9 regulations and explain exactly what documents you need to ensure a smooth customs clearance in 2026.

📋 Key Takeaways for Importers
- It is “Class 9”: Lithium batteries are classified as Class 9 Dangerous Goods (Miscellaneous). They require special labeling.
- The “Golden Paper”: Never ship without a valid UN38.3 Test Report and MSDS.
- FCL is Safer: Shipping Full Container Loads (FCL) is easier than LCL because you don’t risk mixing with other non-compliant cargo.
- Power Limits: Batteries under 100Wh (Watt-hours) have easier regulations than larger storage units.
What is “Class 9” and Why Does It Matter?
International maritime law (IMDG Code) classifies lithium batteries under Class 9: Miscellaneous Dangerous Substances. This doesn’t mean the product is “unsafe.” It simply means that if the container catches fire, the crew needs to know how to handle it.
For the importer, this means two things:
Labeling: Every outer carton must bear the standard “Class 9” diamond label and the Lithium Battery Mark (UN3480 or UN3481).
Strict Packing: Batteries cannot be loose. They must be packed in a way that prevents short circuits and movement.
DP Light Standard: We use reinforced 5-ply export cartons and individual polybags for every unit to meet these strict IMDG standards.
| UN Number | Description | Example Product | Shipping Difficulty |
|---|---|---|---|
| UN 3480 | Lithium Ion Batteries (Loose / Standalone) | Power Banks, 18650 Cells, Spare Battery Packs | High (Strict SOC limits & airline bans) |
| UN 3481 | Packed WITH Equipment | Searchlight + Extra Spare Battery in same box | Medium |
| UN 3481 | Contained IN Equipment | Rechargeable Fans, Camping Lights (Built-in) | Low (Most DP Light products fall here) |
The 3 Documents You Must Ask For
When you are negotiating with a supplier, ask for these three documents before you place the order. If they cannot provide them, do not buy. The goods will likely be blocked at customs.
A. UN38.3 Test Report
This is the “passport” for any lithium battery. It proves the battery has passed 8 rigorous tests, including altitude simulation, thermal shock, and vibration.
Status: Mandatory for Air and Sea freight.
B. MSDS (Material Safety Data Sheet)
A detailed document outlining the chemical composition of the battery. Your freight forwarder and customs broker will demand this to book the shipping space.
Tip: Ensure the MSDS is dated within the current year (2026). Old versions are often rejected by shipping lines.
C. Certificate for Safe Transport of Goods
Issued by a third-party appraisal agency (like DGM China), this certifies that the specific shipment complies with IATA or IMDG rules.
LCL vs. FCL: The Logistics Strategy
For battery products, how you ship is just as important as what you ship.
The Risk of LCL (Less than Container Load)
In LCL shipping, your goods are packed in a shared container with goods from other companies.
The Problem: Many shipping lines refuse to accept LCL shipments of Dangerous Goods because they don’t want to risk mixing batteries with flammable textiles or chemicals from other shippers.
Result: LCL shipping for batteries is often 30-50% more expensive and takes longer to book.
The Benefit of FCL (Full Container Load)
Ordering a full 20ft or 40ft container is the safest bet. Since the entire container contains only your goods, the paperwork is streamlined, and shipping lines are much more willing to accept the booking.
Strategy: If you are a medium-sized distributor, try to consolidate your order to fill at least a 20GP container. It significantly lowers your per-unit shipping risk.
Does “Watt-Hour” (Wh) Affect Shipping?
Yes. Regulations get stricter as the battery gets bigger.
< 100Wh: Most portable fans, emergency bulbs, and camping lights fall into this category. They are easier to ship (often under “Section II” exemptions).
> 100Wh: Large portable power stations or industrial solar systems. These are fully regulated Class 9 DG requiring stricter packaging and higher freight rates.
FAQ (Frequently Asked Questions)
A: Yes, but it is very expensive. Air freight considers lithium batteries a high risk. It is only recommended for urgent samples (sent via specialized couriers like DHL/FedEx DG service), not for bulk inventory.
A: Customs may seize the shipment, and the shipping line can impose fines ranging from $5,000 to $50,000. Always choose an experienced manufacturer like DP Light who understands export compliance.
A: Yes. Even the tiny batteries in remote controls are regulated. Ensure your supplier declares ALL batteries in the shipment, not just the main product battery.
Conclusion: Compliance is Your Safety Net
Sourcing lithium battery products doesn’t have to be a gamble. By ensuring your supplier provides valid UN38.3 reports and adheres to Class 9 packing standards, you eliminate the risk of customs delays.
