Your container of imported olive oil just arrived at the port. The paperwork hasn’t cleared yet. The trucker can’t pick it up. The clock is ticking — and so is a bill you weren’t expecting.
Detention and demurrage fees are among the most frustrating and expensive surprises in food importing. They don’t show up in your freight quote. They don’t care that the delay wasn’t your fault. And for temperature-sensitive cargo, the financial damage can compound fast. Not just in fees, but in spoiled product and broken customer commitments.
Here’s what food importers need to understand about these charges, what drives them, and how to structure your risk strategy before the next port delay hits.
Detention vs. Demurrage: What’s the Difference?
These two terms refer to different charges. And get triggered at different stages of the container’s journey. If you confuse them, it can make it harder to dispute charges, negotiate contracts, or identify where the breakdown actually occurred.
Demurrage: The Port’s Clock
Demurrage is charged by the ocean carrier or terminal when a container sits at the port or terminal beyond the allowed “free time”. This is typically two to five days after the vessel arrives. The container hasn’t been picked up yet. It’s occupying terminal space, and the carrier wants it moved. Every day past free time, fees accrue. These can range from $75 to $300+ per container per day, and they escalate the longer the container sits.
Detention: The Container’s Clock
Detention kicks in once the container has left the terminal but hasn’t been returned to the carrier’s depot within the allotted free time. The container is now in your possession — or your trucker’s — and the carrier wants it back. Free time for container return is typically three to five days. And detention fees run on a similar daily rate structure as demurrage.
Remember this: demurrage is for containers stuck at the port. Detention is for containers stuck with you. Both are expensive. Both are avoidable with the right preparation.
Why Food Importers Get Hit Harder
Port delays are frustrating for any importer. For food importers, they can be catastrophic. Here’s why perishable and temperature-controlled cargo faces a uniquely high level of exposure to supply chain delay costs:
Shelf Life Doesn’t Pause for Port Congestion
A container of fresh produce, dairy, or seafood has a fixed window. Every day sitting at a congested terminal — whether it’s Los Angeles, New York, or Miami — is a day closer to unsaleable product. By the time demurrage fees clear and the container reaches your facility, there’s reduced shelf life, renegotiated pricing with buyers, or outright rejection. The fee is the smallest part of the loss.
FDA and USDA Inspections Add Time
Food imports are subject to FDA review and, for certain products, USDA inspection. These processes take time — time that eats directly into your free time window at the terminal. A routine FDA hold or a re-inspection request can easily push a container past its demurrage threshold before you’ve had any control over the situation. This is a risk factor unique to food importers that general cargo shippers simply don’t face at the same frequency.
Reefer Container Availability Is Tighter
Refrigerated containers — reefers — are in shorter supply than dry containers. Carriers now enforce container return deadlines more aggressively. Detention charges on reefers often run higher, and carriers may escalate faster. When port congestion is systemic (as it was during 2021–2022 and again during recent disruptions), reefer availability tightens even further, creating a compounding pressure on food supply chains.
Who Actually Pays? How Contracts and Incoterms Determine Liability
One of the most common points of dispute in food importing is this: when a delay isn’t clearly your fault, who absorbs the detention and demurrage charges? The answer almost always comes down to your contract terms and the Incoterms governing the shipment.
Incoterms and Risk Transfer
Incoterms — the internationally recognized trade terms published by the International Chamber of Commerce — define when risk and cost responsibility transfer between buyer and seller. For food importers, the most common terms include:
• FOB (Free on Board): Risk transfers to the buyer when the cargo is loaded onto the vessel at origin. Post-arrival port delays and associated fees are typically the buyer’s problem.
• CIF (Cost, Insurance, Freight): The seller arranges and pays for freight and insurance to the destination port, but risk still transfers at the origin port. Demurrage at destination is generally the buyer’s responsibility.
• DDP (Delivered Duty Paid): The seller takes on almost all costs and risks through delivery. Under this term, the seller typically pays detention and demurrage, but food importers rarely use it at scale.
The practical takeaway: if you’re buying on FOB or CIF terms, you’re bearing the risk of port-side delay costs. Make sure your contracts reflect that reality — and that your risk strategy accounts for it.
Carrier Contract Terms Matter Too
Your bill of lading and service contract with the ocean carrier will specify free time allowances and the escalation schedule for fees. These terms are negotiable — especially for importers with consistent volume. If you haven’t reviewed your carrier contracts recently, that’s a meaningful place to start. Extending free time from two days to four can meaningfully reduce your exposure during congestion spikes.
Documentation Tips That Can Reduce Your Exposure
Many detention and demurrage charges are legitimate. But meaningful percentages are disputed and won when importers keep clean documentation. Here’s where it matters most:
• Track arrival notices and free time expiration dates in real time — don’t rely on the freight forwarder alone to flag when the clock starts
• Document every communication with customs brokers, truckers, and terminals — timestamped emails and written confirmations create a paper trail for disputes
• Record FDA/USDA hold notifications and release dates — these can support arguments that delays were government-imposed and outside your control
• Request itemized invoices from carriers — errors in per-diem calculations, container numbers, or date ranges are not uncommon
• File disputes promptly — most carriers have short windows (often 30 days) within which disputes must be submitted
Good documentation won’t prevent every charge, but it gives you the best possible position to challenge the ones that aren’t your fault.
How Risk Strategy Fits Into the Picture
It’s important to be direct here: standard ocean cargo insurance policies do not cover detention and demurrage fees as a rule. Insurers generally treat these charges as a commercial cost of doing business, not an insured loss. That said, how you structure your broader risk program has a meaningful relationship with how port delays affect your bottom line.
Cargo Valuation and Spoilage Coverage
When a port delay results in spoiled or degraded perishable product, the financial loss goes well beyond the demurrage invoice. If your ocean cargo insurance for food includes spoilage and temperature excursion coverage, a portion of that physical loss may be recoverable. This depends on your policy terms and the cause of the delay. This is where food importer risk management conversations get substantive: ensuring your marine cargo policy accurately reflects the value of your perishable shipments and includes appropriate coverage triggers.
Port Congestion and Supply Chain Disruption Planning
Port congestion insurance is an emerging area of the market. And it’s worth understanding what products exist and where the gaps remain. Some specialty marine markets offer contingent business interruption or supply chain disruption coverages that may respond to port-related delays under specific conditions.You should review these highly customized products carefully because their coverage triggers, sublimits, and waiting periods vary significantly. An experienced marine insurance broker can help you understand whether these tools belong in your program.
Frequently Asked Questions About Detention and Demurrage
How much can detention and demurrage fees actually add up to?
More than most importers expect. A single container delayed for two weeks at a major port can generate $2,000–$5,000 or more in combined charges. And that’s before accounting for any product loss. During periods of acute port congestion, importers with multiple containers can face five- and six-figure invoices in a single month. For small and mid-size food importers, this kind of unbudgeted exposure can be operationally destabilizing.
Can I negotiate detention and demurrage fees after they’ve been charged?
Yes, and it’s worth trying. Carriers do sometimes waive or reduce fees. Government holds, terminal equipment failures, or other factors outside the importer’s control commonly cause these delays.Your leverage is higher when you have documentation, you’re a consistent customer of the carrier, and you dispute promptly. Working with a knowledgeable customs broker or freight forwarder who has carrier relationships can also help.
Does my freight forwarder handle demurrage disputes for me?
Sometimes, but not always. Freight forwarders vary in how actively they manage demurrage and detention on your behalf. Some will flag free time windows and coordinate pickups proactively; others primarily handle documentation and leave fee disputes to you. It’s worth having an explicit conversation with your forwarder about their role in managing these charges. And confirming it in your service agreement.

At Coughlin Insurance Services, we help food importers, exporters, and distributors structure insurance programs that stay resilient when port conditions shift and supply chains tighten. Since 1947, we’ve helped food businesses navigate complex global exposures, where a single delayed container can trigger a chain reaction of financial consequences that a standard cargo policy does not address.
Our team understands the practical pressure points behind port delay costs. This includes FDA and USDA inspection timelines, reefer container availability, Incoterms liability gaps, and the coverage questions that arise when perishable product degrades during a terminal hold. We work closely with food importers to align their marine cargo structure with the real risks of moving temperature-sensitive product across global ports. So coverage assumptions match operational reality.
If your company moves food across borders, we can review your current marine cargo or stock throughput structure, assess your valuation and spoilage coverage, and help identify where gaps in your program could turn a port delay into a much larger loss.
