This article will introduce the most common types of containers used in ocean freight and help you understand how to choose the right one for your needs.
What is a Shipping Container?
A shipping container is a large, standardized box used to transport goods. It is designed to fit into ships, trucks, and trains, and is strong, secure, and weather-resistant. Containers are used globally to transport goods and have revolutionized international trade by making the movement of goods more efficient and less expensive.
Types of Shipping Containers
There are various types of shipping containers, each designed for specific types of cargo. Let’s go over the most common ones:
1. Dry Container (Standard Container)
A dry container, also known as a standard container, is the most common type of shipping container. It is fully enclosed and used for transporting general cargo that doesn’t need special environmental conditions.
These containers typically come in two sizes: 20 feet and 40 feet. The 20ft dry container has a capacity of around 33 cubic meters, while the 40ft container has a capacity of about 67 cubic meters. Dry containers are cost-effective and can be used for a wide variety of goods, including furniture, electronics, and textiles.

3. Open Top Container
An open top container is a specialized container that has no solid roof. It’s designed for goods that are too large or too tall to fit into a standard container. Open-top containers allow for top loading and unloading, making them suitable for oversized cargo such as machinery, large equipment, or construction materials.
Open top containers are typically available in both 20ft and 40ft sizes. They offer the flexibility to load items from above, but the open roof means the goods need to be covered with a tarpaulin or other protective materials during transit.
