Introduction
Sea freight remains one of the most reliable and cost-effective ways to ship large volumes of goods from the United Kingdom to the United States. Whether you’re an e-commerce retailer, manufacturer, or importer, understanding how ocean shipping works can save time, reduce costs, and prevent delays.
In this guide, we’ll explain everything you need to know about UK–USA sea freight, including shipping methods, container types, estimated costs, documentation, and the most common questions businesses ask.
1. What Is Sea Freight?
Sea freight, also known as ocean freight, involves transporting cargo across international waters via large ocean-going vessels. Compared to air freight, it’s slower but far more affordable for heavy or bulky goods.
For UK exporters, sea freight is the preferred choice for shipping products such as machinery, vehicles, textiles, food products, and consumer goods to ports in the United States, including New York, Los Angeles, Houston, and Savannah.
2. Sea Freight Options: FCL vs LCL
Full Container Load (FCL):
- You rent an entire container for your shipment.
- Best for large or high-value cargo.
- Offers more security and faster processing.
Less than Container Load (LCL):
- Your goods are shared in a container with other shippers.
- Ideal for small to medium shipments.
- Cheaper, but slightly slower due to consolidation and deconsolidation times.
Example:
If you’re shipping 25 cubic meters of furniture, an FCL (20ft container) is more cost-effective. However, if you’re shipping only 5 cubic meters of goods, LCL is the more cost-effective choice.
3. Major UK and USA Ports
UK Departure Ports:
- Port of Felixstowe – the largest container port in the UK.
- Port of Southampton – ideal for South England and London.
- Port of Liverpool – Convenient for Northern Exporters.
US Arrival Ports:
- Port of New York & New Jersey – main entry point for East Coast shipments.
- Port of Los Angeles / Long Beach – key West Coast destination.
- Port of Savannah – growing in popularity for Southeast US imports.
- Port of Houston – a primary gateway for central and southern states.
4. Container Types & Sizes
| Container Type | Size | Typical Use |
|---|---|---|
| 20ft Dry Container | 33.2 m³ | Standard goods, machinery |
| 40ft Dry Container | 67.7 m³ | Larger shipments, furniture |
| 40ft High Cube | 76.4 m³ | Voluminous but lightweight goods |
| Reefer Container | Varies | Temperature-controlled (food, pharma) |
| Open Top / Flat Rack | Varies | Oversized cargo, vehicles |
Selecting the right container ensures your cargo is secure, cost-effective, and compliant with international standards.
