The Supply Chain at Sea: A Visual Breakdown of Sea Freight Logistics

In today’s globalized world, more than 80% of international trade by volume is transported via sea. From electronics to furniture, automobiles to raw materials, sea freight logistics plays a silent yet monumental role in connecting economies and powering global commerce.

Whether you’re an importer, exporter, eCommerce retailer, or manufacturer, understanding how sea freight works can significantly enhance how you manage costs, delivery timelines, and supply chain reliability.

At Postkodes, we make global logistics smarter and more transparent. In this blog, we take you behind the scenes of sea freight logistics—breaking down how it operates, what it involves, and how you can benefit from efficient, cost-effective shipping solutions across the oceans.

What is Sea Freight Logistics?

Sea freight logistics refers to the end-to-end process of moving goods via cargo ships across international waters. It includes cargo preparation, packaging, booking space on a vessel, container loading, port clearance, ocean transit, and delivery at the destination.

A typical sea freight journey begins with selecting the right sea freight company, choosing between full-container load (FCL) or less-than-container load (LCL), handling customs documentation, and tracking the shipment until it reaches its final destination.

With multiple stakeholders involved—shippers, freight forwarders, port authorities, customs officials, and carriers—the coordination must be seamless. That’s where Postkodes comes in with end-to-end sea freight services that handle all logistics under one reliable umbrella.

Why Choose Sea Freight?

While air freight is best for urgent or small-volume shipments, sea freight stands out for its affordability, scalability, and global reach. Here are some of the top advantages of choosing sea transport:

1. Cost Efficiency

When you’re moving large volumes, sea freight rates per kg are significantly lower than air. Even with longer transit times, the cost savings can be substantial, especially for bulk shipments or heavy goods.

2. Global Coverage

Sea freight connects nearly every continent. Whether you're shipping from Asia to Europe or from the U.S. to Australia, shipping lanes exist to support all major trade corridors.

3. Eco-Friendliness

Compared to air freight, sea transport emits fewer greenhouse gases per kilogram. It’s an environmentally responsible choice for businesses looking to reduce their carbon footprint.

4. Capacity and Flexibility

Containers come in various sizes—20ft, 40ft, and even refrigerated options for perishable items. You can ship anything from furniture and machinery to electronics and textiles with ease.

The Sea Freight Journey: Step-by-Step

To truly understand sea freight logistics, it helps to break down the journey:

Step 1: Booking and Documentation

The process starts with booking space through a trusted sea freight company like Postkodes. Key documents like the Bill of Lading, commercial invoice, and packing list are prepared.

Step 2: Cargo Packing and Pickup

Once booking is confirmed, goods are packed into containers. For smaller shipments, LCL allows businesses to share container space. Postkodes also provides pickup services and packing consultation.

Step 3: Port Clearance and Loading

Cargo is transported to the port and cleared for export. Once cleared, it is loaded onto the ship, stacked with other containers, and readied for departure.

Step 4: Ocean Transit

The ship departs and begins its journey across international waters. This phase can take anywhere from a few days to several weeks, depending on the route and port congestion.

Step 5: Arrival and Customs Clearance

Upon reaching the destination port, cargo is unloaded and inspected. Postkodes handles customs paperwork, import duties, and port charges to ensure smooth clearance.

Step 6: Final Delivery

Once cleared, the container is transported by road or rail to its final destination. Our clients can also use sea freight container tracking to monitor their shipment in real time until it arrives.
