Shipping containers are vital components in global trade, enabling the efficient transport of goods across the world. These robust structures come in various types of shipping containers, and sizes suited to different cargo needs. Understanding their specifications is essential for optimising logistics and ensuring the safe conveyance of goods.

Dry Storage Containers

Dry storage containers are the most common type and are used primarily for shipping a variety of dry goods. They are available in several standard sizes (20ft, 40ft, and 40ft High Cube) and are ISO compliant, ensuring they can be used across different modes of transport. These containers are fully enclosed and weatherproof, providing a safe and secure means of transporting goods.

Refrigerated Containers

Refrigerated containers, also known as reefers, maintain a constant temperature to preserve perishable goods during transit. They come in sizes similar to dry containers but are equipped with a refrigeration unit that allows them to carry food products, pharmaceuticals, and other temperature-sensitive cargo. They are essential for UK’s import and export of perishable commodities.

Specialised Containers

Specialised containers are designed for particular types of cargo that don’t fit into standard containers. These include:

  • Open top containers: Ideal for bulky items that need to be loaded from the top or with a crane.
  • Flat rack containers: With collapsible sides, they are used for heavy and oversized loads.
  • Tank containers: For transporting liquids such as chemicals and food-grade products.

Each of these containers is designed to address specific logistic requirements, adhering to safety and quality standards.

Standard Container Sizes

Containers generally adhere to standardised dimensions to streamline handling and improve interoperability across global supply chains. The common sizes are:

  • 20ft container: Measures 20 feet in length, 8 feet in width, and 8.6 feet in height.
  • 40ft container: Measures 40 feet in length, 8 feet in width, and 8.6 feet in height.
  • 40ft High Cube: Offers an additional foot in height for taller cargo.

These sizes are specified under ISO standards, ensuring they can be stacked, transported, and fitted on a variety of transport vessels, including road, rail, and sea.
