Demurrage Was Budgeted at Zero. The Invoice Was $412,000.
Quote from chief_editor on April 8, 2026, 9:33 pmDemurrage costs are rarely budgeted in physical commodity trades. How port congestion, NOR disputes, and laytime gaps create six-figure surprises.
$412,000. That was the demurrage invoice on a single Supramax voyage, Santos to Mundra, carrying 52,000 MT of raw sugar. The charter party rate was $22,000 per day. The vessel waited at anchorage for 14 days at the load port due to berth congestion and another 5 days at the discharge port waiting for customs clearance. Total delay: 19 days beyond the allowed laytime. The trader had budgeted demurrage at zero. The margin on the entire trade was $380,000.
This is not an outlier. In physical commodity trading, demurrage is the cost that appears after every other number has been fixed. The freight is agreed. The commodity price is locked. The LC is in place. The insurance is arranged. Demurrage sits outside all of these as a variable that most traders acknowledge exists but few model with any precision. Industry estimates suggest that across dry bulk trades globally, demurrage claims amount to roughly $5 to $8 billion per year. The majority of these claims involve disputes over laytime calculation, NOR validity, or the allocation of delay between charterer and receiver.
Laytime Starts When the Notice Is Valid, Not When You Think It Starts
The mechanics of demurrage are deceptively simple. The charter party specifies a number of allowed days for loading and discharging — the laytime. Once laytime is exceeded, demurrage accrues at the agreed daily rate. The clock starts when the vessel tenders a valid Notice of Readiness (NOR). The disputes start with the question of when the NOR is valid.
A vessel arriving at Paranaguá to load soybeans may tender NOR upon arrival at the anchorage area. But if the charter party specifies that NOR can only be tendered when the vessel is at the berth, or when free pratique has been granted, or when customs clearance is completed, the clock does not start at anchorage. It starts later. Conversely, if the charter party allows NOR to be tendered upon arrival at the port limits, whether in berth or not (the WIBON clause — Whether In Berth Or Not), the clock starts ticking while the vessel sits at anchor waiting for a berth that may not be available for ten days.
The difference between these two positions can be $200,000 or more on a single voyage. The trader who sold CFR assumed that the buyer would discharge within the allowed laytime. The buyer assumed that port congestion at Mundra was the port's problem, not theirs. Neither checked the charter party's NOR provisions against the actual port conditions at the time of arrival. The result was a demurrage invoice that exceeded the trade margin.
The operational judgment that matters is this: before fixing a vessel, a trader must verify the current port congestion at both load and discharge ports, confirm the NOR tendering provisions in the charter party match the realistic timeline for berthing, and ensure the contract with the counterparty clearly allocates demurrage risk for delays beyond the trader's control. If any of these three elements is missing or ambiguous, demurrage exposure is unquantified — and unquantified exposure in physical trading is not theoretical risk, it is a cost that has not yet been invoiced.
The Party That Controls Berth Priority Controls the Cost
Port congestion is often described as an external factor, something that happens to the trade. In practice, congestion is frequently a managed condition. Ports allocate berths. Port operators decide priority. Receivers with long-term terminal agreements get berthed first. Spot cargoes wait.
At discharge ports in India, Indonesia, and parts of West Africa, a vessel carrying cargo for a receiver with a terminal services agreement may berth within 48 hours. A vessel carrying cargo for a receiver without such an agreement may wait 10 to 20 days. The demurrage cost of that wait falls on whoever the charter party and the sales contract say it falls on. In a CFR sale, if the contract does not specify demurrage allocation at the discharge port, the seller — who chartered the vessel — may be liable for demurrage caused by the buyer's inability to secure a berth.
This creates a structural imbalance. The seller pays the demurrage. The buyer controls the berth access. The buyer has no financial incentive to accelerate berthing because the cost sits with the seller. In trades where the buyer is a smaller player without terminal agreements, this dynamic is predictable and should be priced into the freight or hedged through demurrage caps in the sales contract. In practice, it is often discovered only when the invoice arrives.
Some traders have started including demurrage pass-through clauses, tying the buyer's discharge obligation to a specific number of days with demurrage beyond that period for the buyer's account. Others specify that if discharge port congestion exceeds a threshold — typically 7 to 10 days — the buyer must reimburse demurrage pro rata. These clauses work when they are negotiated before the fixture. They are rarely accepted after the vessel has already sailed.
The traders who budget demurrage at zero are not being optimistic. They are omitting a cost that, on certain routes and at certain times of year, can exceed the trade margin entirely. The Santos-to-India sugar corridor, the Black Sea-to-North Africa grain route, the Indonesia-to-China coal trade — these are routes where demurrage is not a contingency. It is a line item, and the traders who survive on these routes have learned to treat it as one. The ones who have not learned yet are still waiting to find out how much their next anchorage stay will cost them.
