# War Risk Surcharge vs Premium: What Suppliers See

> War risk surcharge, war risk premium and additional premium explained side by side, with a practical guide to documenting them in a port disbursement account.

## In short

A war risk surcharge is a commercial line item a carrier or operator adds to an invoice to recover the cost of trading into a higher-risk area, while a war risk premium is what a hull and machinery or P&I insurer charges for cover there. Suppliers see the surcharge on paperwork; the premium sits behind it. What matters for a port disbursement account is which one the buyer is paying and how it is allocated.

## Key takeaways

- A war risk surcharge recovers extra trading cost; a war risk premium pays an insurer for cover in the same area.
- The additional premium is the charter-party mechanism that decides which party pays for the risk transfer on a voyage.
- A 2026 Zenodo study found war risk insurance stayed imposed on Nigerian-bound cargo despite falling piracy, citing roughly $1.5 billion paid.
- Show the additional premium as its own PDA line, state its basis and attach the owner's instruction and cover confirmation.
- Ask early whether the call carries an additional premium and who bears it, because the answer shapes how the PDA is built.

A war risk surcharge is a line item a carrier or operator adds to an invoice to recover the cost of trading into a higher-risk area. A war risk premium is what a hull or P&I insurer charges to cover that same area. Suppliers see the surcharge on paperwork; the premium sits behind it, and the two are often confused when a port call is quoted.

For chandlers, bunker suppliers, agents and repair yards, the practical question is not which term is correct. It is which one the buyer is actually paying, and how it lands in the port disbursement account (PDA).

## War risk surcharge, premium and additional premium compared

The three terms describe different things at different points in the commercial chain. The table below sets them out side by side.

TermWho charges itWhat it coversWhere a supplier sees it

War risk surchargeCarrier, operator or traderRecovery of the extra cost of calling at a high-risk portFreight invoice, booking confirmation, rate quotation
War risk premiumHull and machinery or P&I insurerInsurance cover for war, terrorism and related perilsIndirectly, through the owner's or manager's cost base
Additional premiumInsurer, allocated under the charter partyThe extra premium for a specific voyage into a listed areaCharter-party clause, owner's instruction to the agent

The surcharge is a commercial recovery. The premium is a risk transfer. The additional premium is the mechanism that decides who pays for the risk transfer on a given voyage.

## Why the surcharge and the premium diverge

Premiums can stay high long after the risk that justified them has fallen. A 2026 study published on Zenodo examined Nigerian-bound cargo and found that war risk insurance remained imposed despite sharp falls in piracy and kidnapping, describing roughly $1.5 billion paid in recent years in war-risk-related charges ([Zenodo, March 2026](https://doi.org/10.5281/zenodo.18955758)). The paper attributes the persistence to institutional perceptions and market inertia rather than current sea risk.

That matters for suppliers because it explains why a surcharge can appear on a quote for a port where nothing has changed operationally. The buyer is not necessarily responding to a new incident. The pricing may simply be sticky.

Geopolitical events still move the number. According to [gCaptain (October 2026)](https://gcaptain.com/deadly-attacks-on-saudi-arabia-risk-wider-war-that-draws-in-us/), deadly attacks on Riyadh's main airport demonstrated the Houthis' ability to strike at the heart of Saudi power and raised the risk of a wider escalation. Risk pricing in the Red Sea and Gulf responds to that kind of signal, not only to attacks on ships.

## Who pays the additional premium

In a time charter, the charter-party clause usually allocates the additional premium to one party, often the charterer, when the vessel is ordered into a listed area. The owner arranges the cover; the charterer bears the cost. In a voyage charter, the allocation depends on the clause wording and on who gives the order to proceed.

Suppliers rarely see the clause itself. What reaches the agent is an instruction: the vessel is proceeding, cover is in place, and the port costs should be raised accordingly. The agent then has to decide whether the additional premium appears in the PDA or stays on the owner's account.

That compliance layer matters for documentation. A port call in a sanctioned or conflict-affected area may require evidence that cover exists before the agent commits to disbursements. The same 2024 paper notes that sanctions regimes limit activities, finance and insurance services relating to jurisdictions, organisations or individuals, which is why the paperwork around a high-risk call is heavier than the operational work.

The insurance market itself is shifting. According to [Splash247 (October 2026)](https://splash247.com/china-pi-seeks-seat-at-global-insurance-top-table/), China P&I Club has formally applied to join the International Group of P&I Clubs, potentially bringing a mainland Chinese insurer into the grouping for the first time. A broader underwriting base does not remove war risk, but it changes who is quoting it.

## Documenting the surcharge and premium in a PDA

A PDA is the agent's estimate of port costs before the vessel arrives. It is also the document where a war risk item is most often disputed, because the agent is estimating a cost that may be allocated to a different party under the charter party.

Practical steps for chandlers, agents and yards:

1. Separate the insurance-related item from the operational cost. Show the additional premium as its own line, not folded into agency fees.
2. State the basis. Note whether the figure comes from the owner's instruction, the charter-party allocation or the agent's estimate.
3. Attach the evidence. Keep the owner's instruction and any cover confirmation with the PDA file.
4. Flag the allocation. If the charter party places the additional premium on the charterer, say so on the face of the PDA.
5. Reconcile at final disbursement. Compare the PDA line with the final account and explain any movement.

For a chandler quoting stores or a yard quoting repairs, the same discipline applies. If a war risk surcharge is included in the quote, name it. If it is excluded, say so. Buyers in high-risk areas compare quotes line by line, and an unnamed surcharge reads as a hidden cost.

## What this means for suppliers quoting high-risk calls

The operational effect is straightforward. A vessel trading into a conflict-affected area carries a cost base that includes insurance, and that cost base reaches the supplier through the buyer's procurement process, not through the insurer.

Three things follow for chandlers, bunker suppliers, agents and repair yards:

- Ask early whether the call is covered by an additional premium and who bears it. The answer shapes how the PDA is built.
- Keep surcharge and premium separate in every quote. Blending them makes reconciliation harder and invites disputes.
- Watch the risk signal, not only the invoice. According to [The Loadstar (October 2026)](https://theloadstar.com/shippers-stressing-over-risks-from-suez-canal-and-red-sea-transits/), the return of Asia-Europe container services to Red Sea and Suez routing continues despite a deteriorating security situation. Routing decisions change which ports see calls, and which calls carry a war risk line.

The academic picture supports caution. A 2023 study in Heliyon found that piracy risk shows different evolution characteristics in different seas, affected by political situations and anti-piracy measures ([Heliyon, October 2023](https://doi.org/10.1016/j.heliyon.2023.e20988)). War risk pricing behaves the same way: it is local, political and slow to normalise.

A 2024 paper in the International and Comparative Law Quarterly examined the five-powers war risk exclusion, which automatically terminates cover in the event of war between China, France, the United Kingdom, the United States and Russia ([Cambridge University Press, July 2024](https://doi.org/10.1017/s0020589324000204)). Suppliers do not need the clause wording, but they should know that cover can change by event, not only by geography.

## Frequently asked questions

### What is the difference between a war risk surcharge and a war risk premium?

A war risk surcharge is a commercial line item a carrier or operator adds to recover the cost of trading into a higher-risk area. A war risk premium is what a hull or P&I insurer charges to cover that area. The surcharge appears on invoices; the premium sits in the owner's cost base.

### Who pays the additional premium in a time charter?

The charter-party clause usually allocates the additional premium to one party, often the charterer, when the vessel is ordered into a listed area. The owner arranges cover and the charterer bears the cost. Voyage charters depend on the clause wording and who gives the order.

### Why do war risk premiums stay high after piracy falls?

A 2026 study on Zenodo found that war risk insurance remained imposed on Nigeria-bound cargo despite sharp falls in piracy and kidnapping, attributing persistence to institutional perceptions and market inertia rather than current sea risk. ([Zenodo (CERN European Organization for Nuclear Research)](https://doi.org/10.5281/zenodo.18955758))

### How should a port agent document a war risk item in a PDA?

Show the additional premium as its own line, state whether it comes from the owner's instruction or the charter-party allocation, attach the cover confirmation, and reconcile it at final disbursement. Blending it into agency fees makes disputes more likely.

### Can war risk cover change without a new incident?

Yes. A 2024 paper in the International and Comparative Law Quarterly examined the five-powers war risk exclusion, which automatically terminates cover in the event of war between China, France, the United Kingdom, the United States and Russia. Cover can change by event, not only by geography. ([International and Comparative Law Quarterly (Cambridge University Press)](https://doi.org/10.1017/s0020589324000204))

### How can a ship chandler act on war risk pricing before a vessel arrives?

VesselReach shows vessels near your ports and scheduled arrivals, identifies the company behind each vessel and finds operations, chartering and procurement decision-makers. You can raise the war risk question and present your quote before the PDA is fixed.

## More on this topic

A war risk surcharge is the line a carrier adds to recover the cost of trading into a riskier area. It is not the same as the war risk premium an insurer charges for cover, or the additional premium a charter party allocates to one party. Suppliers see the surcharge on a quote and the premium only through the buyer's cost base. In a PDA, the additional premium should be a separate line with its basis stated and the owner's instruction attached. Ask early who bears the additional premium, keep surcharge and premium apart, and watch routing changes that move calls between ports.

The single most useful point for a supplier is that the surcharge on a quote and the premium behind it are two different costs. The surcharge is the carrier's recovery of trading into a higher-risk area, while the premium is the insurer's charge for cover, and the additional premium is the charter-party mechanism that decides who pays. In the port disbursement account, the additional premium belongs on its own line with its basis stated and the owner's instruction attached.
