Charter Party Red Flags: What Freight Directors Miss Before Signing
Key Takeaways
- WIPON/WIBON can count anchorage time against laytime — model worst-case waits before signing.
- Weather and holiday exceptions do not extend to demurrage unless the CP says so in writing.
- Request demurrage caps where congestion risk is material; uncapped exposure can exceed freight.
- Match cesser clauses to back-to-back sale terms so demurrage liability passes to the receiver.
- Ice clause versions differ materially — read the wording for each winter-risk port.
Most charter party disputes are not caused by bad faith. They are caused by clauses that were read quickly, misunderstood, or assumed to be standard when they were not. By the time the dispute surfaces — at the discharge port, in an arbitration filing, or in a demurrage claim three months after the fixture — the commercial damage is already done.
These are the clauses where the money hides.
WIBON, WIPON, WIFON, WICONBON — and why the difference is material
Whether In Berth Or Not. Whether In Port Or Not. Whether In Free Pratique Or Not. Whether In Customs Or Not But On Berth.
Each of these defines when laytime starts, and each produces a meaningfully different result at congested ports. The combination of these clauses in a single charter party — which is common — creates a laytime commencement date that is earlier than most charterers expect.
WIPON means laytime starts when the vessel arrives at the port, regardless of whether a berth is available. At Qinhuangdao or Paradip during peak season, vessels can anchor for 5–8 days before berthing. Under WIPON, that waiting time counts against your laytime. Under a berth charter without WIPON, it does not.
The practical test before signing: identify the worst-case anchorage waiting time at your load and discharge ports over the last 12 months. Apply the NOR commencement clause to that scenario. If the resulting laytime exposure is unacceptable, negotiate. WIPON is not standard — it is a negotiating position that owners insert and charterers routinely accept without reading.
Laytime definitions that are not what they appear
"Weather Working Days" sounds protective. Whether it is depends entirely on whether the clause extends to the demurrage period or is limited to laytime.
The default position under English law, confirmed repeatedly in arbitration, is that exceptions to laytime do not automatically extend to demurrage unless the charter party says so explicitly. A WWD clause that reads "laytime shall not count during periods of bad weather" stops protecting you the moment laytime expires and demurrage begins.
If you are trading on routes with material weather risk — Australian east coast during cyclone season, Brazilian ports during the wet season, Black Sea during winter — you need the exception clause to explicitly state "and such time shall not count as demurrage." Four words that can be worth $80,000 on a single fixture.
Similarly: "SHEX" (Sundays and Holidays Excepted) requires the charter party to specify whether it applies UU (Unless Used). SHEX UU means if you load on a Sunday, that time counts. SHEX EIU (Even If Used) means it does not. These abbreviations appear in term sheets without explanation and are signed without being checked against the actual charter party wording.
Demurrage caps and why owners resist them
A demurrage cap limits the total demurrage liability to a fixed amount — typically expressed as a multiple of the daily demurrage rate, or as a fixed dollar figure. On long-haul fixtures with high port congestion risk, caps are standard practice in sophisticated freight procurement. On shorter fixtures or in markets where owners have leverage, they are often absent.
The argument for always requesting a demurrage cap: your maximum financial exposure on any single fixture should be calculable before you sign. Uncapped demurrage at a chronically congested port — Paradip has recorded vessels waiting 14+ days for berth during peak iron ore season — can produce claims that dwarf the freight cost itself.
Owners resist caps because they transfer port congestion risk to the vessel side. The negotiating middle ground is a cap set at a level that reflects genuine commercial exposure: typically 15–20 days of demurrage at the applicable rate. Below that, you are asking the owner to absorb risks that are genuinely outside their control.
The cesser clause trap
A cesser clause releases the charterer from liability once cargo has been loaded and the bill of lading has been issued. In theory, this is protection for the charterer. In practice, it is often worthless — and occasionally actively harmful.
Under English law, the cesser clause operates in conjunction with the owner's lien on cargo. The owner retains a lien on the cargo for freight, demurrage, and general average. If the cargo receiver does not pay demurrage at the discharge port, the owner can exercise that lien — detaining the cargo until payment.
The problem: if your sale contract does not pass demurrage liability to the buyer in the same terms as the charter party, you face a gap. The receiver refuses to pay, the owner exercises the lien, your buyer complains about delayed delivery, and you are in the middle with exposure from both directions.
Before signing any charter party with a cesser clause, confirm that your back-to-back sale contract passes the demurrage obligation to the receiver in identical terms. Cesser clauses that are not backed by a matching sale contract provision are not protection — they are a liability waiting to crystallise.
Ice clauses and the allocation of waiting time
On fixtures touching Baltic, Black Sea, or northern Chinese ports between November and April, ice clauses determine who bears the cost of delays caused by ice conditions. The range of outcomes is wide: some ice clauses treat ice waiting time as laytime; others exclude it entirely; others split the exposure between owner and charterer.
The BIMCO standard ice clause allocates ice-related delays differently depending on whether the vessel is at the load port or the discharge port, and whether ice is present at the time of arrival or develops after arrival. Neither version is automatically favourable to charterers — both require active management of NOR timing and port agent reporting to support a dispute.
If your fixture touches an ice-risk port, read the specific ice clause wording, not just the heading. "BIMCO Ice Clause" is not a single standard — there are multiple versions in circulation, and the differences between them are material.
The practical checklist
Before countersigning any charter party, verify:
WIBON/WIPON/WIFON — what is the earliest possible laytime start at the actual ports involved?
Do WWD, SHEX, or any other exceptions explicitly extend to the demurrage period?
Is there one? If not, what is the realistic maximum exposure given historical port congestion?
Does the back-to-back sale contract pass demurrage liability to the receiver in matching terms?
Which version applies, and what does it say about waiting time at each specific port?
None of these require legal review on every fixture. They require a freight director who has read the charter party carefully enough to know what is in it.
