In international sea freight, buyers (importers) can face unexpected costs. Two of these, often confused, are demurrage and detention charges. In this article, we will examine what these two concepts mean for buyers and why they are important.

What is Demurrage?

Demurrage in sea freight is a delay fee that the buyer has to pay when the full container remains within the port or terminal premises beyond the agreed free time. This free time starts from the moment the container is discharged from the vessel and represents the period allowed for the buyer to pick up the cargo from the port.

Why Do Buyers Pay Demurrage?

• Delays in Customs Clearance: Prolonged customs procedures preventing the buyer from picking up the cargo on time.
• Missing or Incorrect Documentation: Lack of or errors in the necessary import documents causing processing delays.
• Issues in the Buyer's Internal Logistics Planning: Delays in the buyer's warehousing or transportation arrangements.
• Port Congestion: General congestion at the port preventing the timely removal of cargo (even if beyond the buyer's control, the cost is usually passed on to the buyer).

What is Detention?

Detention in sea freight is a delay fee that the buyer pays when they take the full container outside the port or terminal premises and fail to return the empty container to the carrier (shipowner or shipping company) within the agreed free time. This free time covers the period from when the empty container reaches the buyer's warehouse, is unloaded, and is returned to the carrier's designated depot or port.

Why Do Buyers Pay Detention?

• Prolonged Unloading Time: The buyer's inability to unload the container on time due to warehousing or operational reasons.
• Late Return of the Empty Container: Failure to return the empty container to the carrier's designated location within the agreed timeframe (logistical issues, returning to the wrong depot, etc.).

Importance of Demurrage and Detention for Buyers:

• Additional Costs: Demurrage and detention charges can significantly increase import costs and negatively impact profitability. These fees, applied daily, can amount to substantial sums depending on the delay period.
• Supply Chain Disruptions: Delayed cargo deliveries and container returns can negatively affect the buyer's production plans, customer deliveries, and overall supply chain.
• Relationship Management: Frequent demurrage and detention payments can strain relationships with carriers and other logistics partners.

How Can Buyers Avoid Demurrage and Detention Costs?

• Effective Planning: Making a realistic plan for picking up the cargo and returning the container, considering estimated arrival times.
• Fast Customs Clearance: Preparing all necessary documents in advance and working closely with a customs broker to expedite customs procedures.
• Efficient Internal Logistics: Optimizing warehousing and transportation processes to ensure the quick pickup and unloading of cargo.
• Monitoring Free Time: Carefully tracking the free time granted by the carrier and acting within these periods.
• Communication with Carriers: Sharing potential delays with carriers in advance and seeking solutions.
• Attention to Contract Details: Carefully reviewing and understanding the demurrage and detention terms in shipping contracts.

Conclusion:

Demurrage and detention can be significant cost factors for buyers in sea freight. Understanding the reasons for these charges and how to avoid them will help importers control their logistics costs and manage their supply chains more efficiently. Effective communication, careful planning, and time management are key to avoiding these unexpected expenses.
