Decoding Shipping Container Conditions: WWT, CW, and IICL Explained
As a container expert, one of the most frequently asked questions I receive is about the different conditions of used shipping containers. When shopping for used shipping containers, it’s essential to understand the different condition ratings. This guide will break down the difference between Cargo Worthy (CW), Wind and Water Tight (WWT), and IICL (International Institute of Container Lessors) guidelines to help you choose the right container for your needs.
Understanding Shipping Container Conditions
When buying used shipping containers, it’s important to know the difference between the three main conditions: ASIS, Cargo Worthy (CW), and Wind and Water Tight (WWT). ASIS containers are easy to identify as they are fully depreciated and usually have visible holes or damages.
In the world of shipping containers, the terms Cargo Worthy (CW), Wind and Water Tight (WWT), and IICL are frequently mentioned when discussing used container conditions. However, the distinctions between these conditions can be unclear, especially when it comes to the less apparent differences between CW and WWT containers. In this post, we’ll help clarify these terms and explain their significance when purchasing a used shipping container.
Cargo Worthy (CW)
Cargo Worthy containers are suitable for shipping cargo overseas. If you plan to use a shipping container to transport your products, you’ll need a CW container that has been inspected by a marine/maritime surveyor. The surveyor will ensure the unit meets the CSC (International Convention for Safe Containers) requirements, and if it passes, they will issue a certificate stating that the container is seaworthy or Cargo Worthy. This document is required by port authorities before the container can be loaded onto a vessel and shipped.
If you need a high-quality used container, CW is the safest option, as they generally have better quality than other conditions.
Wind and Water Tight (WWT)
WWT containers may have some patches or repairs from previous shipping use but do not have leaks or holes. While they don’t meet the CSC requirements for overseas shipping, WWT containers are sufficient for storing items and are often purchased as storage units. If you plan to use a shipping container as a storage box, WWT containers are recommended to save money, as there is a significant price difference compared to CW containers.
IICL
IICL (International Institute of Container Lessors) units represent the highest grade of used shipping containers. These containers have been inspected and certified to meet strict IICL standards, ensuring they are in excellent condition for shipping or storage purposes. IICL units are often chosen when clients require containers in near-new condition or for specific projects that demand top-quality units.
In summary, understanding the differences between Cargo Worthy, Wind and Water Tight, and IICL units is essential when purchasing a used shipping container. By knowing the specific requirements and characteristics of each condition, you can make an informed decision and choose the right container for your needs.
