Shipping Delays Explained: Why Your Container May Be Late

24.06.2025

In global logistics, timing is everything. Yet even the most carefully planned shipments can encounter delays. For businesses and individuals relying on ocean freight, a late container can disrupt operations, increase costs, and cause frustration. So, what actually causes shipping delays—and can they be avoided?

Let’s break it down.

1. Port Congestion

One of the most common culprits. Major ports like Savannah, Long Beach, or Rotterdam often face backlogs due to high traffic volumes, labor shortages, or outdated infrastructure. When too many vessels arrive at once or unloading takes longer than expected, containers sit idle for days—or even weeks.

Tip: Choose less congested ports when possible and work with experienced freight forwarders to anticipate peak times.

2. Customs and Documentation Issues

Incomplete or incorrect documentation can lead to customs inspections and holds. Even small mistakes—wrong VIN number, missing invoice—can delay a container for days.

Tip: Double-check all documents and partner with a logistics provider that handles customs clearance professionally.

3. Weather and Natural Disasters

Storms, hurricanes, typhoons, or unexpected natural events can reroute ships or halt operations at ports. Unlike other issues, this one is purely beyond human control.

Tip: Build extra time into your schedule, especially when shipping during hurricane or monsoon seasons.

4. Container Availability & Equipment Shortages

Sometimes it’s not the ship that’s missing—it’s the container. Global container shortages have become more frequent due to imbalanced trade flows and surging demand.

Tip: Book your shipment early and maintain regular communication with your shipping partner about equipment availability.

5. Strikes and Labor Disruptions

Port workers, customs officials, or trucking companies may go on strike, halting operations. Even short strikes can create long-lasting ripple effects in the supply chain.

Tip: Stay informed on port news and rely on 3PL providers who can reroute or reschedule quickly.

6. Transshipment Delays

If your container changes vessels at a hub port, delays at the connection point can occur—especially if the second vessel is full or behind schedule.

Tip: Opt for direct shipping routes where possible, or allow for longer lead times.

7. Overbooking by Carriers

Shipping lines may overbook containers like airlines overbook seats. If there’s not enough space, your container might be “rolled” to the next sailing.

Tip: Early bookings and working with premium carriers can help reduce the risk.

How to Minimize the Risk of Delays

  • Use experienced freight forwarders

  • Include buffer time in your delivery schedule

  • Choose reliable carriers and ports

  • Invest in cargo tracking and real-time updates

  • Get shipping insurance to protect against financial losses
