What is sea freight? Discover everything you need to know about ocean shipping, from how it works to types, cost, and tips for choosing a reliable provider.
Introduction to Sea Freight
Sea freight, also known as ocean freight, refers to the transportation of goods via cargo ships across international waters. It is one of the oldest and most cost-effective methods for moving bulk goods, especially when compared to air freight or rail transport.
With more than 90% of global trade conducted through maritime routes, sea freight plays a pivotal role in keeping international commerce alive and affordable. Whether you’re a business looking to import machinery or a company exporting finished products, understanding sea freight is essential to optimizing your logistics strategy.
How Sea Freight Works
Sea freight is a multi-step process involving several key stakeholders and logistical stages:
Key Players in Sea Freight
- Shippers: The owners or exporters of the goods.
- Consignees: The recipients or importers.
- Freight Forwarders: Companies that coordinate and manage the shipment.
- Shipping Lines: The carriers that own and operate the cargo vessels.
- Customs Brokers: Specialists in clearing goods through customs procedures.
Basic Process Overview
- Cargo Booking: The shipper contacts a freight forwarder or shipping line to book space.
- Packing & Loading: Goods are packed into containers and transported to the port.
- Port Clearance: Customs documentation is submitted.
- Ocean Transit: The cargo ship sails to the destination port.
- Unloading & Final Delivery: Goods are cleared, unloaded, and delivered inland.
Types of Sea Freight Services
Different shipments require different types of sea freight services depending on the volume, urgency, and nature of goods.
FCL (Full Container Load)
- Entire container is reserved for one shipper.
- More secure and cost-effective for large shipments.
LCL (Less than Container Load)
- Cargo shares container space with other shipments.
- Suitable for smaller volumes but may experience delays.
Bulk Cargo
- For unpackaged goods like grain, coal, or oil.
- Shipped directly in vessel holds.
