Shipping cars with batteries requires special handling and documentation because the high-voltage battery is classified as a dangerous good (DG) for international sea freight.

While this sounds complex, it is a standard and safe procedure when managed by an experienced export partner. The unique challenge with shipping electric vehicles (EVs), plug-in hybrids (PHEVs), and other new-energy vehicles (NEVs) is not the vehicle itself, but the large lithium-ion battery it contains. International maritime regulations classify these batteries under specific codes (like UN 3171) to ensure they are transported safely, minimizing any potential fire risk. This classification triggers a more rigorous documentation and handling process compared to shipping a traditional petrol or diesel car.

Here’s what buyers need to know about the process.

The Critical Document: Material Safety Data Sheet (MSDS)

Every EV or hybrid model has a unique MSDS for its battery pack. This document, provided by the manufacturer, details the battery’s chemical composition, potential hazards, fire-fighting measures, and safe handling instructions.

Shipping lines and port authorities will not allow a vehicle with a high-voltage battery to be loaded onto a vessel without a valid and approved MSDS. It is the single most important piece of paperwork specific to EV shipping. As your export partner, Starvia Automotive ensures the correct, up-to-date MSDS is obtained from the factory and submitted to the carrier as part of our Export Documentation and Customs Support.

Battery State of Charge (SoC) Requirements

To further enhance safety, carriers require the vehicle's battery to be at a specific state of charge—typically between 20% and 50%. A fully charged or fully depleted battery is considered less stable for long-distance transport. Before the vehicle is delivered to the port, the exporter must ensure the SoC is within the carrier’s accepted range. This is a standard pre-shipment check for all NEVs.

How an Exporter Manages the Process

Successfully shipping a car with a battery involves a clear, compliant workflow. When you work with an export partner, the steps are managed for you:

  1. DG Declaration: The vehicle is declared as containing dangerous goods on all shipping documents.
  2. Documentation Submission: Starvia Automotive submits the vehicle's MSDS and other required paperwork to the shipping line for approval before the vessel’s arrival.
  3. SoC Verification: The vehicle’s battery level is checked and adjusted to meet the carrier’s requirements before it enters the port.
  4. Safe Loading: The vehicle is loaded via RoRo (Roll-on/Roll-off) or secured in a container according to strict safety protocols for dangerous goods.

By following these established procedures, shipping an EV from China is just as reliable and secure as shipping any other vehicle.
