Sea Freight

Navigate new frontiers of global trade with SLG Logistics’ sea freight shipping services.

Sea freight, also known as ocean freight, involves the shipment of cargo via container ships between ports around the world. As a sea freight forwarder, SLG Logistics specialises in arranging efficient transportation of goods by sea.

Sea freight is ideal for shipping large volumes of non-perishable freight in consolidated containers. By consolidating cargo from multiple customers, we achieve a full container load of pallets (FCL), reducing costs for all parties involved.

Items that are commonly shipped by sea freight: 

  • Manufactured components and machinery
  • Vehicles and construction equipment
  • Non-perishable foodstuffs like grains, beverages and packaged goods
  • Consumer goods such as electronics and clothes
  • Furniture, fixtures and bulk packaging
  • Perishables (in refrigerated containers)
Some restrictions apply to dangerous materials, which require special handling and documentation.

Whether you need cargo shipping from the UK to China, Singapore, India or beyond, SLG offers quality sea freight solutions to navigate for international trade.

Why Choose Sea Freight?


Choosing sea freight for shipping overseas offers significant cost savings over other freight forwarding methods, like air freight, which can come up to 5-6X the cost of sea freight.

Big Capacity

Sea freight shipping is ideal for bulk orders, offering the flexibility and capacity needed for substantial freight volumes.

Safe Transport

Shipment by sea ensures that goods are securely transported over long distances, with robust handling and storage protocols to minimise risks during transit.

Global Reach

Shipment by sea gives you access to an extensive global network to stay connected to distant markets, which makes it a superior choice for international trade.


Sea freight is a reliable solution for international shipments as scheduled container ship sailings run on a regular weekly/biweekly basis along major trade lanes.

Environmental Friendliness

Transporting goods by sea is more energy efficient per tonne-mile than other modes and reduces carbon footprint and overall emissions.

Sea Freight FAQs

Who is sea freight suitable for?

Customers often choose sea freight as the mode of transport to ship goods that are not urgently needed, bulky, and/or large in quantity. This may include stocks of bulky furniture, machinery, or vehicles that are transported via RoRo (roll-on roll-off) ships.

Sea freight is a suitable option for various individuals and businesses shipping to and from countries around the world, such as:

  • Manufacturers transporting goods between Australia and Singapore.
  • Chinese suppliers shipping raw materials to Singapore.
  • US retailers sending consumer items to Singapore.
  • UK importers transporting machinery parts to Southeast Asian markets.
  • Singaporean exporters trading with customers in North America.

Consolidating smaller cargo volumes onto container ships also makes sea freight an affordable solution for small-to-medium-sized businesses engaging in international trade.

Typical transit times for sea freight shipments can range from 3-5 weeks for cargo shipped between continents. Shipment duration depends on the departure and arrival ports and weather conditions.

The main documents required are the commercial invoice, packing list, bill of lading, cargo insurance documents, and any necessary CITES permits or certificates of origin/conformity. Customs clearance paperwork, including customs entry documents, are also needed at both the origin and destination ports.

Yes, it’s possible to arrange door-to-door shipping via sea freight.

Freight forwarders coordinate the full shipment, including pick up, ocean transit on container vessels, and delivery. This provides one-stop responsibility and visibility for seamless, door-to-door service.

The main difference between sea freight and air freight is the speed of transit. Air freight uses aircraft to ship cargo internationally in a matter of days but at a much higher price per unit. Sea freight transports on container ships and takes weeks for global delivery, making it far more affordable over long distances.

Sea freight can handle larger volumes and consolidated shipments of general goods since it’s not constrained by aircraft size and weight allowances like air freight. However, air is preferable for small, high-value items or those needing rushed transit like perishables.

While air freight offers greater trackability, sea tracking depends on subsequent carriers once containers discharge at destinations. Both require customs paperwork coordination, but air uses express clearance versus advanced processing for sea. Overall, forwarders recommend sea or air based on shipment urgency, size and affordability needs.

While it’s possible to handle customs clearance yourself, it’s generally recommended to use a customs broker or agent, especially for international shipments. They have expertise in navigating complex customs regulations and can help avoid delays or issues with your shipment

Yes, it’s highly recommended to get freight cargo insurance. While sea freight is generally safe, there are risks involved in long-distance transportation. Insurance protects against loss or damage during transit. The cost of insurance is typically a small percentage of the cargo’s value and offers shippers peace of mind.

No, there is no difference between ocean freight and sea freight. These terms are used interchangeably in the shipping industry to transport goods by sea.
