Port Congestion at Paranaguá: The Cost the Seller Quoted Did Not Include
Quote from chief_editor on May 20, 2026, 3:30 pmBrazilian soybean exports from Paranaguá experience chronic seasonal congestion. The waiting time converts directly to demurrage that the freight estimate did not cover.
February. The peak of the Brazilian soybean export season. A Panamax vessel, nominated by a European grain trader for FOB loading at Paranaguá, Brazil, tendered its Notice of Readiness on a Thursday morning. The vessel was at anchor off the port, waiting. It would wait for six days before a berth became available.
The charterparty specified 4 days total laytime, SHINC, for loading. Day one of laytime began when the NOR was accepted — the vessel was still at anchor. By the time the vessel reached the berth, two days of laytime had already been consumed. Loading took three days. Total time against laytime: five days on a four-day allowance. One day of demurrage at $11,000 per day. An $11,000 charge that was not in the freight estimate.
For context: the same trader's vessel loading at Santos in the same week waited nine days before berthing. Demurrage on that cargo: five days at $11,000, totaling $55,000. The grain trade margin on a Panamax soybean cargo in a competitive market can be measured in tens of thousands of dollars. Demurrage at this level does not just reduce the margin — it can eliminate it.
The Paranaguá Problem Is Not New and Not a Surprise to Anyone Who Works the Route
Paranaguá is Brazil's largest grain export terminal and one of the most congested agricultural ports in the world during harvest season. The congestion is chronic, seasonal, and structurally embedded: Brazilian soybean production has expanded significantly over the past decade, port infrastructure investment has not kept pace, and the export season concentrates loadings into a narrow weather-dependent window.
Shipping brokers who work the Santos-Paranaguá corridor year-round track vessel waiting times as part of their standard market intelligence. Average waiting times at Paranaguá during February-April have historically ranged from 5 to 12 days during peak season, depending on the year's harvest volume, vessel clustering patterns, and terminal operational status. This is not hidden information — port agents publish it, shipping databases track it, and it is discussed openly among traders who work Brazilian grain.
The question is why the trader in the example above had a charterparty with a 4-day total laytime that did not account for the structural reality of the port they were loading at, in the month they were loading. The charterparty terms were presumably negotiated with a freight broker. The freight broker's job is to find the vessel at the best rate. The laytime terms that apply to the specific port during the specific season are a separate negotiation — one that requires specific knowledge of port operations rather than just freight market rates.
A charterparty negotiated for Paranaguá loading in February that provides only 4 days total laytime is not a mistake — it is a standard term offered by shipowners who understand that the port is congested and that congestion risk falls to the charterer under WIBON. The charterer who accepts it without negotiating for port congestion exceptions or longer laytime allowances is accepting a structure that will produce demurrage in most years.
The Exception Clauses That Could Have Applied
Some charterparties for Brazilian grain loading include port congestion exception clauses — provisions that exclude waiting-for-berth time from laytime calculation when the delay is caused by port congestion rather than by the charterer's actions. These clauses are not given freely; shipowners resist them because they transfer congestion risk back to the vessel's account. But they are negotiable in certain freight market conditions, particularly when excess vessel supply gives charterers bargaining power.
A trader who loads regularly from Paranaguá during peak season and does not consistently try to include congestion exception language in charterparties is paying demurrage that could, at least partially, be avoided through better contract structuring. The cumulative cost over a trading year can represent a significant number — and it appears in the demurrage account rather than in the freight estimate, which means it frequently goes unanalyzed as a controllable cost.
