WWT vs Cargo Worthy Shipping Containers: What’s the Difference?
Looking for a shipping container but confused by terms like WWT and Cargo Worthy? You’re not alone. One of the most common questions we get at MidSouth Container Sales & Rentals is: “What’s the difference between a WWT container and a Cargo Worthy container?”
Here’s a simple breakdown to help you choose the right container for your needs.
What Does WWT Mean?
WWT stands for Wind & Water Tight. A WWT container is built to keep the elements out — making it an excellent, cost-effective solution for storage.
Key Features:
- No major holes or leaks
- Doors seal properly
- Keeps wind and rain out
- Structurally sound for ground-level storage use
Best Uses for WWT Containers:
- On-site storage at construction sites
- Farm equipment and agricultural storage
- Workshops and job-site tool storage
- Household and personal storage units
WWT containers are generally more affordable and may show cosmetic wear such as dents, surface rust, or patched areas — but they remain functional and secure for storage purposes.
What Is a Cargo Worthy Container?
A Cargo Worthy (CW) container meets a higher inspection standard and is certified suitable for international shipping and freight transport.
Key Features:
- Structurally stronger than WWT
- Floors, walls, and doors pass rigorous inspection
- Approved for use in international shipping
- Excellent long-term storage and transport protection
Best Uses for Cargo Worthy Containers:
- International shipping and export
- Freight and commercial transport
- Long-term commercial storage
- Export-related businesses
Because they meet stricter certification standards, Cargo Worthy containers generally carry a higher price point than WWT containers.
