Sea Freight Shipping Explained: What You Need to Know Before Booking Cargo by Sea
In 2025, sea freight remains the backbone of global trade, accounting for over 80% of international cargo volume. Whether you're a first-time importer or a seasoned logistics manager, understanding how sea freight works can help you save costs, reduce transit time, and avoid delays at port. This guide breaks down key concepts, container types, shipping terms, and what you need to know before booking.
1. What Is Sea Freight Shipping?
Sea freight, also known as ocean freight, is the transportation of goods in large volumes via cargo ships. It's the most cost-effective way to move heavy or bulk goods internationally—especially over long distances.
There are two main modes:
FCL (Full Container Load): You rent an entire container (20ft or 40ft).
LCL (Less than Container Load): You share a container with other shippers.
✅ Best for: High-volume goods, large items, non-urgent shipments
2. Key Terms You Must Know
Before you book cargo by sea, get familiar with these logistics terms:
| Term | Meaning |
|---|---|
| FOB (Free On Board) | Seller pays until goods are on the ship |
| CIF (Cost, Insurance & Freight) | Seller pays until goods arrive at destination port |
| Bill of Lading (B/L) | Legal document confirming receipt and shipment details |
| HS Code | Harmonized System code used for customs declaration |
| ETA/ETD | Estimated Time of Arrival / Departure |
3. Container Types and Sizes
| Container Type | Use Case |
|---|---|
| 20ft Standard | Heavy but compact cargo (e.g., machinery) |
| 40ft Standard | Light but voluminous goods (e.g., furniture) |
| 40ft High Cube | Extra height for taller cargo |
| Reefer (Refrigerated) | Perishables, pharma |
| Open Top / Flat Rack | Oversized or irregular cargo |

Freight Rate (per container or CBM)
Origin Charges: Export handling, documentation
Destination Charges: Terminal handling, import clearance
Customs Duty & VAT
Inland Trucking Fees
Optional: Insurance, detention/demurrage, warehousing
Always ask for a “total landed cost” quote to avoid hidden charges.
7. Do You Need a Freight Forwarder?
Unless you're experienced, yes. A licensed freight forwarder will:
Handle documentation & customs
Coordinate with carriers and ports
Offer multimodal solutions (sea + rail/truck)
Monitor shipping schedules & delays
