Short answer: yes — used EVs leave China by RoRo routinely — but a battery-powered vehicle is dangerous goods (Class 9) under the International Maritime Dangerous Goods (IMDG) Code for sea transport, and after a series of car-carrier fires since 2022, shipping lines apply their own EV policies that differ by carrier, route and vessel. The practical rule: acceptance, limits and any state-of-charge requirement must be confirmed in writing by your forwarder for the specific sailing before you commit money.

The rule framework

Sea transport of dangerous goods is governed by the IMDG Code, maintained by the International Maritime Organization (IMO dangerous goods page; the server returned an automated-access error at our 2026-09-05 check — open it in a browser). Within that framework, battery-powered vehicles including pure EVs are classified as Class 9 dangerous goods (UN 3171, battery-powered vehicle). Two consequences matter to buyers:

  • The shipment needs dangerous-goods documentation — a DG declaration handled by your forwarder, not just a commercial invoice.
  • Loose or spare lithium batteries are a separate, stricter category (UN 3480 batteries alone; UN 3481 packed with equipment). The practical rule for used-car exports: no spare battery packs in the cabin or container — a spare pack turns the shipment into a fully regulated battery consignment.

Why every carrier’s answer is different

The IMDG Code sets the floor; carriers set the operating policy above it. Since the high-profile car-carrier fires of 2022–2023, marine insurers and lines have tightened EV carriage, and policies have kept evolving: per-vessel or per-deck EV count limits, state-of-charge caps at gate-in (commonly required in the 30–50% range, evidenced by a dashboard photo), no charging aboard, designated deck placement, and — importantly — refusal of damaged EVs, whose battery packs are treated as a far higher fire risk. This carrier-differences layer is why a generic “yes, EVs are fine” from a salesperson is not an answer you can ship on.

What to confirm in writing before booking

  • EV accepted on the specific route and vessel, and any quota that could bump your car to a later sailing.
  • The state-of-charge cap and how it is evidenced at gate-in.
  • Policy on damaged or accident-repaired EVs — if your unit has any battery-related repair history, disclose it before booking, not at the port.
  • Who prepares and signs the DG declaration, and the document cut-off dates.
  • If containerized instead: container DG booking rules for a car with a lithium-ion battery installed.

The China-side export track for used EVs

Used EVs (and hybrids) exported through the used-car channel follow the ordinary used-car export regime — licensed exporter, per-shipment export licence, third-party inspection report with battery checks under WM/T 8-2022 (Announcement 2024 No. 6, official, checked 2026-09-05). Do not confuse this with the separate export licence regime for new pure-electric passenger vehicles that took effect 2026-01-01 (Announcement 2025 No. 54, official, checked 2026-09-05) — if a seller mixes up the two regimes, that is a competence signal.

When you need a professional

Use a forwarder with genuine dangerous-goods experience on car trade, and let them handle the DG declaration. If a forwarder says EVs need no DG paperwork, walk away — that shortcut is where shipments get stuck at the port.

Sources and scope

Framework: IMO IMDG Code page (official, automated-access error at check; checked 2026-09-05); carrier-practice context from industry loss-prevention guidance (TT Club, industry insurer, checked 2026-09-05); China-side regimes from MOFCOM announcements (official, checked 2026-09-05). Carrier-specific EV policies are operational and change without notice — the written confirmation described above is the only reliable source for your shipment.
