Are Marine Insurers Charging an EV Surcharge?
Not as a line item. In 2026 marine underwriters price EV carriage through conditions of cover — SOC limits, detection evidence and cargo warranties.
No — not as a clean per-vehicle surcharge. Marine insurers in 2026 price electric-vehicle carriage mainly through conditions of cover: state-of-charge limits, evidence of early fire detection, and cargo-declaration warranties that decide whether EV cargo is covered at all. Headline vehicle-carrier rates have hardened, but the EV-specific load shows up as underwriting requirements, not a labelled tax.
Is there an 'EV surcharge' line item?
Mostly on the freight invoice, not the insurance one. Shippers booking EVs in 2026 do see line items labelled "EV surcharge," "battery handling fee" or "hazardous cargo premium" — but those are largely carrier and forwarder charges covering stowage, handling and emergency-response cost, not the marine insurer's premium. On the insurance side, IUMI and the broker market describe EV pricing as conditional and case-by-case, not a published rate card. Conflating the two overstates what underwriters are actually charging for the battery itself.
How insurers actually price EV exposure
Through the terms, not a flat load. Gallagher's marine guidance is blunt that "applying loss prevention measures will be critical to obtaining insurance cover for the marine transport of EVs" — cover availability, not just price, turns on risk management.
- State-of-charge limits — a charge below roughly 30% reduces thermal-runaway severity, and SOC caps appear as a control condition.
- Pre-loading battery inspection and testing, including battery-management and dashboard checks and interfacing with ports of call.
- Correct cargo declaration for used EVs, a review of packaging and safety measures, and a fit-for-transport stipulation.
- Evidence of early detection and a documented loading procedure — the audit trail, not just the presence of equipment.
Why it isn't a simple EV tax
The casualty evidence doesn't support a flat battery surcharge. IUMI's own position, set out in its 1 September 2023 best-practice paper for the safe carriage of electric vehicles, is that there are fewer fires from EVs than from conventional vehicles driven the same distance, and only a minor difference in total energy released once either burns. So underwriters target fire frequency and response capability for any vehicle, rather than levying a surtax tied to propulsion type — the same fuel-agnostic logic the regulators are using.
What is driving the harder market
Concentration of value and a rising fire count. Allianz Commercial's Safety and Shipping Review 2025 recorded 250 ship fire incidents in 2024 — up 20% year on year and the highest in a decade — and notes the latest car carriers can load as many as 10,000 vehicles, so a single deck fire concentrates enormous value and salvage exposure. Allianz's own framing is that the EV fire risk at sea is "not under control." That is the backdrop underwriters are pricing against, EV-specific surcharge or not.
What this means for operators
Stop shopping for an "EV rate" and start assembling the file. The underwriting requirements — SOC policy, detection audit trail, cargo-declaration discipline — are the same ones the P&I renewal questionnaires now ask for, so the work compounds across hull, cargo and protection-and-indemnity. An operator that can document early detection and a controlled loading interface negotiates from a different position than one presenting only a vessel list, whether or not a line item ever says "EV."

Questions, answered
Do marine insurers add an EV surcharge for car carriers?+
Not as a clean per-vehicle line item. In 2026 marine underwriters price EV carriage through conditions of cover — state-of-charge limits, pre-loading battery inspection, cargo-declaration warranties and evidence of early detection — rather than a published EV rate. Cover availability, not just price, turns on those risk-management terms, per broker guidance from Gallagher and others.
Then what are the 'EV surcharges' shippers see on quotes?+
Those are mostly freight-side charges — carrier and forwarder line items for stowage, battery handling and emergency-response cost — not the marine insurer's premium. They are real, but conflating them with insurance pricing overstates what underwriters charge for the battery itself. The insurance load shows up as conditions and warranties, not a labelled surcharge.
Why don't insurers just charge a flat EV premium?+
Because the casualty evidence doesn't support it. IUMI's 2023 best-practice paper notes fewer fires from EVs than conventional vehicles over the same distance, and only a minor difference in total energy released once either burns. Underwriters therefore price fire frequency and response capability for any vehicle, not a surtax tied to propulsion type.
What lowers an operator's EV-related insurance cost?+
Evidence, not negotiation. Independent detection telemetry, a documented loading procedure, a state-of-charge policy and clean cargo declarations are the file underwriters condition cover on. The same items appear in P&I renewal questionnaires, so the work compounds across hull, cargo and protection-and-indemnity and moves an account off the top of the band.
