Korean Used Car Dangerous Goods Declaration: Shipping EV & Hybrid Batteries by Sea (2026)

A Korean used car dangerous goods declaration is the shipping document that classifies a vehicle — or the lithium battery it carries — as dangerous goods under the International Maritime Dangerous Goods (IMDG) Code, so it can be transported safely by sea. It applies mainly to electric vehicles and hybrids because of their lithium-ion batteries, and to any car shipped with a loose, damaged, or spare battery. A normal petrol or diesel car usually does not need one.

As Korean EV and hybrid exports climb, this once-obscure paperwork has become a make-or-break step for buyers of an Ioniq, EV6, Niro, or any battery car. Get the Korean used car dangerous goods declaration right and your EV sails on schedule; get it wrong and the car is refused at the terminal, the shipper is fined, and the exporter can be blacklisted by the carrier. This guide explains, in plain English, which cars trigger it, the UN numbers that decide everything, state-of-charge limits, RoRo versus container rules, the documents involved, the costs, and how to avoid a misdeclaration. It fits directly into our step-by-step buying process and builds on the Korean EV export guide, which many first-time EV buyers read first.

What Is a Korean Used Car Dangerous Goods Declaration?

Dangerous goods are cargoes that pose a risk to a ship, its crew, or the environment — explosives, flammable liquids, and, most relevant here, lithium batteries. The Korean used car dangerous goods declaration is the signed document (often called the Shipper's Declaration for Dangerous Goods, or DGD) that tells the carrier exactly what hazardous item is inside, under which UN number, and how it has been prepared for safe carriage.

Three ideas sit behind it:

• It is about the battery, not the bodywork. A used EV can be in flawless condition and still be dangerous goods, purely because a large lithium-ion pack stores enough energy to catch fire and is very hard to extinguish at sea.
• It is a legal statement, not a formality. The shipper signs the declaration and personally certifies that the classification and packing are correct. That signature carries real liability if it is wrong.
• It is carrier- and rule-driven. The framework is the IMDG Code, published by the International Maritime Organization (IMO), but each shipping line layers its own acceptance policy on top — which is why the same EV can be routine on one carrier and refused on another.

Korea ships roughly 2.4 million vehicle units a year (KAMA / KITA), and battery-electric and hybrid models are the fastest-growing slice of that flow. Every one of those battery cars needs the dangerous-goods question answered before it can be booked. This is the logistics step that sits underneath the model choice covered in our EV and hybrid guides.

Which Cars Actually Trigger It — EV, Hybrid & ICE

Not every car is dangerous goods. The trigger is the battery. Here is how the main categories usually fall — always confirmed case by case with the carrier, because policies differ.

Battery-electric vehicles (BEVs)

Full EVs — Hyundai Ioniq 5 and 6, Kia EV6 and EV9, and similar — carry a large high-voltage lithium-ion pack and are almost always treated as dangerous goods. Expect a declaration, a state-of-charge limit, and possible restrictions on vessel and mode. If you are exporting one of these, read the Ioniq 5 export guide or the Kia EV6 export guide alongside this article, and browse live EV stock in our Hyundai inventory and Kia inventory.

Hybrids and plug-in hybrids (HEV / PHEV)

Hybrids — Niro HEV, Sorento hybrid, Ioniq HEV — carry a smaller lithium (or, on some older models, nickel-metal-hydride) battery. Many are still handled under dangerous-goods rules because of the lithium pack, though the treatment is often less onerous than a full BEV. A plug-in hybrid, with its larger pack, sits closer to a BEV. Do not assume "it's just a hybrid" removes the requirement.

Conventional petrol and diesel cars (ICE)

A standard internal-combustion car with only a small 12-volt starter battery, shipped in the normal way, is generally not a full dangerous-goods case and moves under ordinary vehicle carriage. The picture changes only if a spare or loose battery, or hazardous accessories, are shipped with it.

The UN Numbers That Decide Everything

Under the IMDG Code, every dangerous item has a four-digit UN number and a proper shipping name. For used-car export, four entries do almost all the work, and choosing the correct one is the heart of the whole declaration. Get the UN number right and the rest of the paperwork follows; get it wrong and you have a misdeclaration.

The critical divide is UN3171 versus UN3480. A working EV shipped complete is a battery-powered vehicle (UN3171). The moment that battery is out of the car — removed for any reason, shipped as a spare, or written off as defective — it becomes a lithium battery in its own right (UN3480), with much tougher packing, labelling, and acceptance rules. Treating a loose or defective battery as if it were installed is one of the most dangerous mistakes in the whole process.

State of Charge, RoRo vs Container & Carrier Rules

Once a car is classified as dangerous goods, three practical constraints shape how it actually ships.

State of charge (SoC)

A full lithium battery stores more energy and carries more thermal-runaway risk than a partly charged one, so carriers and dangerous-goods rules commonly require EV and hybrid batteries to travel at a reduced charge — often around 30%, or whatever level the shipping line specifies. Delivering the car at full charge can get it turned away. Treat any single percentage as an estimate and confirm the exact figure with your carrier before the car goes to the port.

RoRo versus container

Battery cars complicate the usual choice between roll-on/roll-off and container shipping. Some RoRo carriers accept EVs under strict dangerous-goods conditions; others refuse them, pushing the car into a container where it can be braced, monitored, and isolated. Container carriage may also be mandated for damaged or higher-risk batteries. Weigh this against the general trade-offs in our RoRo shipping guide and container shipping guide — for an EV, the dangerous-goods policy often decides the mode for you.

Carrier-by-carrier policy

There is no single rule across the industry. Each shipping line publishes its own lithium-battery and EV acceptance policy — permitted vessels, maximum SoC, stowage position, and paperwork lead time. The same Ioniq 5 might be routine with one carrier and refused by another on the same route, which is why an experienced exporter matches the car to a line that will take it.

The Documents in a DG Shipment

A dangerous-goods EV shipment carries a few documents that a normal used-car shipment does not. The centrepiece is the declaration itself; supporting papers back up the classification.

• Shipper's Declaration for Dangerous Goods (DGD): the signed statement of UN number, proper shipping name, class, mode, and SoC — the core of the whole DG declaration.
• Material Safety Data Sheet (MSDS / SDS): the battery's safety data sheet, often requested by carriers to confirm the chemistry and hazards.
• Container Packing Certificate (CTU): where the EV ships in a container, confirmation that it was packed, braced, and secured correctly.
• Battery condition / test evidence: proof the pack is healthy and, where required, that its state of charge is within the limit.

These sit on top of the standard export pack — Bill of Lading, commercial invoice, and export declaration — and feed into the carrier's own manifest and stowage planning. The details you provide here also flow into the vessel's cargo manifest and advance filings, so accuracy at this stage matters downstream.

The DG Booking Process, Step by Step

For a battery car, the dangerous-goods work happens early — before a sailing is confirmed. Here is the typical sequence.

1. Screen the battery. Confirm the pack is healthy, not under recall, and installed in the car. Any spare or removed battery is flagged now.
2. Classify. Assign the correct UN number and hazard class — the decision the rest of the shipment depends on.
3. Match the carrier. Select a shipping line whose lithium-battery policy accepts this car on your route and mode.
4. Prepare the car. Bring the battery to the required state of charge and secure the vehicle for safe stowage.
5. File the declaration. Submit the signed DGD plus the MSDS and any packing certificate within the carrier's lead time.
6. Load and sail. The car is stowed in its approved position and the vessel departs on schedule.

Skipping or rushing steps 1 and 2 is where problems start. A battery discovered to be defective at step 4 — after a sailing is booked — can blow up the whole schedule.

Damaged, Defective & Recalled Batteries

This is the danger zone. Damaged, defective, or recalled lithium batteries are the most restricted dangerous-goods category, and most ocean carriers heavily limit or outright refuse them because they carry the greatest fire risk.

A battery is treated as damaged or defective if it has been in a crash or fire, is swollen or leaking, is under an active safety recall, or throws battery fault codes. Any of these can make a car un-shippable by normal means until the battery is assessed, repaired, or removed and handled under special provisions.

• Disclose, always. A concealed defective battery is both a safety hazard and a serious legal exposure. Carriers and inspectors test for this.
• Recalls matter. Some EV models have had battery recalls; a car with an open recall may be restricted until the recall work is verified.
• Screening belongs in Korea. A reputable exporter checks battery health before booking, so a problem surfaces at the yard — not mid-ocean or at the destination port.

Cost, Timeline & What Misdeclaration Costs You

Shipping a battery car as dangerous goods costs more and takes a little longer, but the real financial danger is doing it wrong. The chart below ranks the typical cost exposure — from a routine surcharge to a full misdeclaration event.

Normal costs. Budget a dangerous-goods surcharge on top of freight — commonly an estimated USD 150 to USD 600 or more per unit or container, plus documentation handling and, where a carrier will not take the EV as RoRo, the higher cost of container carriage. The classification and filing add a few days of lead time. All figures are estimates that move with carrier policy, route, and space, so request a specific dangerous-goods quotation for your exact car.

The cost of getting it wrong. Ship a lithium-battery car without the correct declaration and you are exposed to a held or refused container, substantial fines, and being blacklisted by the carrier for future bookings. Because the shipper signs the DGD, that liability lands on whoever books the cargo. Against a three- or four-figure surcharge, a proper declaration is cheap insurance — the same logic buyers weigh throughout our how-to-buy guide.

How SH GLOBAL Handles DG & Battery Shipping
