Business owners in the export and import sectors know that transportation of goods is a significant cost item. It's time to learn all about containerized shipments from DiFFreight experts. This method leads in demand from our clients on long-distance routes, largely due to its affordable rates.

Containerized Freight — Advantages

This refers to the transportation of goods in metal containers suitable for sea, rail, and road transport.

Key advantages:

  • Versatility: goods can be transported by different modes of transport without unloading individual items. This reduces time and financial costs for loading and unloading.
  • Security: protection of contents from external influences and minimizing damage.
  • Cost savings on packaging: many goods are transported in primary or simplified packaging.
  • Logistics optimization: effective storage, consolidation at CFS terminals, and simplified processing at ports.
  • Flexibility for entrepreneurs: you can purchase either the entire container or just part of it. This ensures lower shipping costs compared to air delivery.

The most common are 20-foot and 40-foot containers with capacities of about 33 m³ and 67 m³, respectively. There are models with larger volumes, 45-foot in length, and smaller 10-foot containers. We recommend our article about container sizes, which lists all parameters.

Why Containerized Freight is Optimal for Any Cargo

Containers are suitable for various types of cargo. They serve as universal "containers" made of metal that are resistant to weather conditions. The walls and base are exceptionally durable. A 40-foot dry cargo container can hold up to 28.8 tons!

After filling and sealing, the container is lifted by a crane to a rail platform or ship’s hold. Which types of cargo are suitable for this transportation?

  • General Cargo: goods in packaging, on pallets, or in boxes;
  • Liquid Cargo: liquids and chemicals (special tanks are used);
  • Bulk Cargo: grain, sugar, mineral fertilizers;
  • Hazardous Cargo: chemicals, flammable substances (special models are required);
  • Oversized Cargo: machinery and metal constructions are transported on FlatRack platforms.

There are some limitations, such as explosives, radioactive materials, and perishable products without temperature control.

Two Types of Loading:

  • Consolidated Freight (LCL). Shipments of small batches without needing to buy the entire container. The cost is divided proportionally to the volume occupied. This is a cost-effective solution for small and medium businesses.
  • Full Container (FCL). This is a safer and faster option as there is no unloading of goods, minimizing damage, but the cost is, of course, higher.


Containerized international shipments are associated with risks: delays in ports due to terminal overload, damage from careless loading, and long customs checks. There can be force majeure events: weather conditions, strikes, or technical failures. To reduce risks, it is important to plan logistics carefully, always insure the cargo, and choose reliable carriers.

How to Choose the Right Container: Expert Explanation

Let’s take a detailed look at the types of containers used for sea freight.

Standard (Dry Container) — versatile, suitable for most general cargo.


Refrigerated Containers with cooling systems are used for transporting perishable goods (meat, fish, fruits) and other items requiring specific temperature and humidity, such as medicines.


Open-top containers have a removable roof for tall and oversized cargo.


FlatRack Platforms come without walls or roofs. They are suitable for heavy and oversized cargo that cannot fit into standard or open-top containers.


Tank Containers for liquids and gases with enhanced sealed construction and leak protection.


Flexitank — a soft tank placed inside a standard container. This type is used for safely transporting liquid cargoes like oils, juices, and technical fluids. Here's how it is arranged inside schematically:


When selecting, consider the type of cargo, storage conditions, route, and packaging requirements. For example, perishable goods require a reefer container, equipment requires a FlatRack. General cargo is usually transported in dry containers, in boxes or on pallets.

Freight for Containerized Shipments by Sea

Freight is the cost. It depends on the delivery terms under Incoterms: for example, under EXW, the buyer takes on all expenses, including freight, while under CIF the seller pays for delivery to the port of destination.

The price is calculated taking into account:

  • the type of container;
  • the distance and route;
  • carrier tariffs;
  • seasonal demand fluctuations;
  • additional services (insurance, brokers, import documentation handling, warehousing).

The cost is also influenced by the taxes of the country of departure, the cost of transshipment at ports during transit, and volume. Tariffs also fluctuate depending on the season and holidays. For example, freight rates for shipments from China to Ukraine increase before the Chinese New Year due to container and labor shortages.
