As an experienced UK freight forwarder, we operate across more than 280 branches globally, enabling us to manage and monitor your cargo from origin to final destination through a fully integrated sea freight logistics network.

Shipping Options

We specialise in both LCL and FCL ocean freight shipping, offering cost‑effective options for shipments of all sizes. LCL ocean freight is ideal for smaller volumes, where cargo is consolidated to optimise space and reduce costs. FCL ocean freight suits larger volumes, providing dedicated container solutions for improved efficiency and control.

Trade Lanes

We operate dedicated LCL consolidation services to and from Australia and New Zealand, plus reliable export LCL services to New York. Through our global co‑load network, we offer competitive LCL solutions across all major international trade routes. Our global FCL freight services prioritise Mainfreight network locations, delivering consistent service standards, full visibility, and seamless door‑to‑door ocean freight management.

Customs & Compliance

Our in‑house customs brokers manage all documentation, regulatory compliance, and border formalities as part of our integrated ocean freight offering. Services include customs clearance, tariff classification, excise clearances, under‑bond transitional facilities, and certified degassing in accordance with SER regulations. As an ISO 9001:2008 and AEO‑certified UK freight forwarder, we deliver secure, compliant, and reliable ocean freight services backed by full visibility and end‑to‑end control.

Frequently Asked Questions about our Ocean Freight Services in the United Kingdom

Find answers to the most common questions about our ocean freight services to help you better understand how we support your supply chain needs.

How do I know whether LCL or FCL is right for my shipment?

At Mainfreight, choosing between LCL and FCL depends on what best supports your supply chain. LCL suits cargo that doesn’t fill a full container and offers a cost‑effective, flexible option by consolidating your freight with other shipments. FCL is ideal for larger volumes or when you need greater control over timing, handling and security, with your goods moving in a sealed container. Our team reviews your volumes, timelines and priorities to recommend the most efficient, cost‑effective solution.

What container types and sizes are available, and which is most suitable for my shipment?

Understanding container sizes and equipment types helps determine the best option for your ocean shipment. Common choices include 20GP, 40GP and 40HC containers, depending on cargo volume, weight and dimensions. Specialised equipment is also available, including reefers for temperature‑controlled goods, open‑top containers for over‑height cargo and flat racks for oversized or out‑of‑gauge freight. Our team can assess your shipment and recommend the most suitable, cost‑efficient container type.

What are Incoterms?

Incoterms (International Commercial Terms) are globally recognised rules that define the responsibilities of buyers and sellers during the movement of goods. They outline who manages transport, insurance, export and import customs clearance, and the transfer of risk at each stage of the shipment. By clearly stating where responsibilities start and end, Incoterms help prevent misunderstandings, support smoother international transactions, and keep your supply chain operating with clarity and confidence.

What is demurrage and detention?

Demurrage applies when containers remain at the port beyond the allocated free time, with charges incurred once that period is exceeded. Detention applies after the container leaves the port and is held longer than the agreed free time, resulting in additional costs. In simple terms, demurrage covers time inside the port, while detention covers time outside. Our team helps manage these timeframes to minimise costs. Some carriers merge both into one free period, and extra port‑storage charges may apply.

What documentation is required for ocean freight?

The documentation required depends on your cargo, origin and destination, and getting it right is essential to keep freight moving smoothly. Most shipments need a commercial invoice, packing list and bill of lading, while some goods may also require certificates of origin or import and export licences. At Mainfreight, we simplify documentation by working closely with you to understand your shipment and ensure everything is prepared correctly, helping avoid delays, reduce risk and keep your supply chain efficient.

How do I track my cargo?

With Mainfreight, visibility of your cargo is simple, reliable and always accessible. Our Mainchain portal provides real‑time tracking, letting you view milestones, check statuses and access shipment details whenever needed. Technology is only part of the experience, which is why our operations teams are always available to support you with updates, questions or guidance. This combination of powerful technology and genuine human expertise keeps you informed and your cargo moving confidently.
