Understanding Shipping Delay Charges: Demurrage, Detention, and Per Diem Explained

Introduction: The Complex World of International Shipping

In the ever-evolving landscape of global trade, international shipping stands as a cornerstone of business operations. Whether you're a small enterprise shipping a single container occasionally or a large corporation managing multiple daily shipments, understanding the intricacies of ocean freight is crucial for maintaining smooth operations and healthy partnerships.

One of the most challenging aspects of international shipping is dealing with delays and the associated charges. These can significantly impact your bottom line and disrupt your supply chain. In this comprehensive guide, we'll delve into the often misunderstood world of shipping delay charges, focusing on three key terms: demurrage, detention, and per diem.

The Misconception: Storage vs. Delay Charges

Before we dive into the specifics, it's important to address a common misconception in the industry. Many importers and exporters use the terms demurrage, detention, and per diem interchangeably, often assuming they all refer to storage charges. However, this is not the case.

Storage charges are indeed levied when your shipment stays beyond the allowed free time at various facilities such as ports, airline terminals, rail facilities, or bonded warehouses. These fees compensate the facility for the use of their space and equipment. However, demurrage, detention, and per diem charges are distinct from storage fees and serve different purposes.

Demurrage Charges: The Cost of Container Usage

Demurrage is a term you'll frequently encounter in ocean freight shipping. But what exactly does it mean?

Definition and Purpose

Demurrage charges are fees imposed by steamship lines and airlines to compensate for the use of their shipping containers beyond a specified free time period. These containers, whether used for sea freight or air freight (in some cases), are valuable assets for carriers, and they aim to ensure their efficient turnover.

How Demurrage Works

When your shipment arrives at the port of destination, you're typically granted a limited number of free days to pick up your container. This free time can vary depending on the carrier and location. Once this free period expires, demurrage charges kick in for each additional day the container remains at the port.

Escalating Costs

One crucial aspect of demurrage charges to be aware of is their tendency to escalate over time. For instance, you might face a structure like this:

• 7 days of free container usage
• $100 per day for the next 3 days
• $250 per day from day 11 to day 17
• $350 per day for any day beyond day 17

This escalating structure is designed to strongly discourage using containers for extended storage and to incentivize quick turnaround.

Payment and Impact

It's important to note that all demurrage charges must be paid in full before you can pick up your shipment. These fees can vary significantly between carriers and ports, potentially having a substantial impact on your shipping costs if not managed properly.

Detention Charges: The Price of Time

While demurrage relates to container usage at ports, detention charges focus on a different aspect of the shipping process.

Primary Definition: Trucking Delays

Detention charges primarily apply to domestic trucking. These fees are billed by trucking or drayage companies when the loading or unloading of your shipment or containers takes longer than the allocated free time.

How Detention Works

Typically, you're granted a free time or grace period of around one to two hours for loading or unloading a container. This can vary depending on whether it's a domestic shipment or destined for import or export. Once this free time is exceeded, detention fees start to accumulate, usually billed at an hourly rate.

Congestion-Related Detention

Detention charges can also apply in cases of facility congestion. If a trucker has to wait due to busy conditions at a port or railroad dock, these waiting times may incur detention fees. Unfortunately, these charges often apply even when the congestion is beyond your control or that of your freight forwarder.

Secondary Definition: Container Storage

In some contexts, detention can also refer to a storage charge. Some carriers might use the term "detention" when you leave a container shipment at the terminal beyond the allowed free time. However, this usage is less common and is more typically referred to as "per diem" charges.

Per Diem Charges: The Daily Equipment Fee

"Per diem," Latin for "per day," is another crucial term in the shipping industry that often causes confusion.

Definition and Application

Per diem charges apply when you require the use of carrier equipment beyond a set amount of free time. This equipment can include ocean containers and unit load devices (ULDs) used in air freight.

How Per Diem Works

Similar to demurrage and detention, per diem charges come into effect after a certain number of free days, which can vary depending on the equipment type and carrier. For imports, these charges apply to cargo leaving the arrival terminal. For exports, they apply to shipments leaving the departing terminal.

Accumulation and Return

An important point to remember is that per diem charges continue to accumulate until you return the equipment to the terminal of the port, rail yard dock, or airline. This ongoing accumulation can lead to significant costs if not managed carefully.
