Sea Freight Shipping

Sea freight, also known as ocean freight, refers to the transportation of goods via cargo ships. It’s one of the most commonly used shipping methods and is a vital part of international trade.

Sea freight shipping is often the preferred choice for heavy or bulky items like machinery, vehicles, and raw materials: this is because it’s particularly cost-effective for shipping large volumes of goods over long distances.

Sea freight quotes will vary according to supply and demand, external pressures (e.g., political or economic), and even difficult environmental circumstances (bad weather).

How does the sea freight shipping process work?

International sea freight shipping involves several steps to make sure goods are safely transported from the point of origin to their final destination. Here’s a more detailed look at what you can expect from the sea freight process:

1. Choosing a freight forwarder

The first step is to select a reputable freight forwarder who will handle the logistics of your shipment. Freight forwarders provide a range of services, from negotiating sea freight shipping rates to managing the entire transport process.

2. Export haulage

Export haulage involves transporting goods from the supplier's location to the freight forwarder's warehouse or directly to the port.

3. Origin handling

At the origin warehouse, the goods are inspected, consolidated, and loaded into containers. The freight forwarder makes sure that the cargo is correctly packed and labelled for international transport.
Origin handling also includes planning for loading, stuffing containers, and moving them to the port​.

4. Export customs clearance

Before the goods can leave the country of origin, they must clear customs. Customs clearance involves submitting the necessary documentation to customs authorities to declare the goods and pay any applicable duties and taxes.

5. Sea freight shipping

The containers are loaded onto cargo ships for the sea journey. The freight forwarder coordinates with shipping lines to choose the best vessel and route for the shipment.
The actual transit time on the water can vary depending on the destination; for example, shipping from China to the UK may take 21–30 days.

6. Import customs clearance

Upon arrival at the destination port, the goods must clear import customs. This involves another round of documentation and payment of any import duties and taxes.

7. Destination handling

Once cleared by customs, the containers are transported from the port to a destination warehouse. Here, the goods are unloaded, inspected, and prepared for final delivery.

8. Import haulage

The final leg of the journey involves transporting the goods from the destination warehouse to the consignee's location: this is usually done by road and can be arranged by the freight forwarder or a local trucking company.
The goal is to deliver the goods safely and on time to the recipient​.

How should I prepare my goods for sea freight?

Once you receive competitively priced sea freight quotes from Freight Broker, you need to think about preparing your goods. International sea freight should always be packaged in a manner that considers the goods being shipped and the level of protection they need.

1. Choose the right packaging


Selecting the appropriate packaging is essential. Goods should be packed in sturdy, reinforced materials such as corrugated cardboard boxes, wooden crates, or metal containers, depending on the nature and weight of the items.
For bulk shipments, pallets are ideal as they provide structure and support.

2. Use internal cushioning


To prevent damage during transit, use adequate internal cushioning. Materials such as foam, air cushions, and packing peanuts can help absorb shocks.

3. Seal packaging securely


Properly sealing your packages is critical. Use strong packing tape, and be certain that all seams and flaps are reinforced. For heavier goods, stronger tape or additional layers may be required to secure the packaging effectively.

4. Label clearly


Label your packages clearly with all necessary information, including handling instructions like "Fragile" or "This Side Up." Accurate labelling means that handlers are aware of how to properly manage your goods throughout the sea shipping process​.

5. Prepare documentation


Accurate documentation is essential for avoiding delays at customs clearance. Be certain that all required documents, such as the Bill of Lading, packing lists, and commercial invoices, are prepared and included with your shipment​.

What documentation is required to ship a cargo by sea?

While sea freight quotes include the rates for shipping your goods, there are other costs associated with the administrative side of the operation.

1. Bill of Lading (B/L)


The Bill of Lading is a critical document in sea freight. It serves as a receipt for the cargo, a document of title, and a contract for carriage.
It details the type, quantity, and destination of the goods and must be presented at the destination for the consignee to take possession of the cargo.​

2. Commercial invoice


The commercial invoice is a document issued by the seller and includes details about the goods being shipped, such as their description, quantity, and value. It serves as the basis for the customs declaration and is essential for calculating duties and taxes.

3. Packing list


A packing list provides detailed information about the contents of each package in the shipment. It includes measurements, weight, and item descriptions, which assist in customs clearance.

4. Certificate of origin


The certificate of origin verifies the country where the goods were manufactured. It’s often required for customs clearance to determine the applicable tariffs and to confirm eligibility for any trade agreements.

What are the different types of sea freight services?

Effective sea freight comparison requires an understanding of the two main types of transport: Less-than-Container Load (LCL) and Full-Container Load (FCL).

1. LCL


LCL shipping is ideal for smaller shipments that don’t require the full space of a container. In this service, multiple shipments from various shippers are consolidated into a single container.

2. FCL


FCL shipping involves the use of an entire container for a single shipment.

What are the advantages of shipping goods via sea freight?

Thousands of businesses search for sea freight quotes every day. That’s because it’s an excellent way to ship goods internationally, mainly due to the following advantages:

1. Emissions

Compared to other forms of freight transport, sea freight offers shippers a more environmentally friendly alternative. It’s a greener choice because cargo ships produce far fewer CO2 emissions per ton of cargo transported.

The lower carbon footprint of sea freight is crucial for companies aiming to minimise environmental impact while adhering to sustainability goals.

2. Value and capacity

Sea freight’s cost-effectiveness for transporting large, bulky shipments is another notable advantage. The economies of scale achieved by transporting vast quantities of goods at once mean that sea freight often costs less per unit compared to air or road freight.

Plus, cargo ships' substantial capacity means that they can handle oversized items and large volumes that would be impractical for other transport methods​.

3. Fewer restrictions

Sea freight imposes fewer restrictions on the types of goods that can be transported.

This flexibility makes it possible to ship a wide variety of items, including hazardous materials and oversized machinery, which might be challenging or more costly to send via air or road.

What do you need to take into consideration when shipping goods via sea freight?

While sea freight shipping is reliable and economical, there are still numerous circumstances you should take into account.

1. Protection: Goods transported via sea freight shipping are subject to various handling stages and environmental conditions, such as loading and unloading at ports, exposure to saltwater, and potential rough seas.
Shippers must take extra precautions to safeguard their cargo from damage.
2. Speed: While sea freight is not the fastest shipping method, it’s often the most economical for bulk shipments. Transit times can vary significantly depending on the route and the ports involved.
3. Dependability: When sourcing sea freight quotes, shippers must be aware that, as with any mode of transport, cargo ships are still susceptible to delays caused by adverse weather conditions, port congestion, and customs hold-ups.
