ISO Certified shipping containers are designed to meet specific international standards, which include structural integrity and dimensions suitable for shipping.
However, itβs important to note that a container can be ISO certified but not cargo worthy if it hasnβt passed the necessary inspections to ensure itβs in good condition for transporting cargo. In this case, while the container meets ISO standards for design and size, if it has significant damage, rust, or other issues that affect its ability to safely carry cargo, it would not be considered cargo worthy.
ISO certification focuses on compliance with international shipping standards, while cargo worthy status is more concerned with the physical condition of the container.
Both certifications are crucial for ensuring safe and effective transport, especially for cargo shipped overseas.
In conclusion, we offer different types of graded containers that can meet various needs.



A Containers: These containers are gently used and well-maintained. They may show minor signs of wear, but they are structurally sound and fully functional. Grade A containers are perfect for businesses that want a balance between cost-effectiveness and quality, offering a reliable option for storage or shipping without breaking the bank.
B Containers: These containers have seen moderate use and may have some cosmetic imperfections, such as dents or scratches. However, they are still structurally sound and suitable for various applications. Grade B containers are a great option for those looking for budget-friendly solutions while still ensuring functionality and safety.
C Containers: These containers are older and show significant signs of wear. They may have more noticeable dents, rust, or other cosmetic issues. While they may not be suitable for all shipping needs, they can be used for storage or other less demanding applications. Grade C containers offer a cost-effective option for those who prioritize price over aesthetics.
We categorize our containers into different grades: Grade A, Grade B, and Grade C.
Grade A containers are typically in excellent condition, often new or nearly new, while Grade B containers are in good condition with minor cosmetic issues. Grade C containers may show significant wear and tear and might not meet cargo worthy standards.
One-Trip Containers: These containers are in like-new condition, having been used only once for shipping cargo. They are ideal for businesses looking for high-quality storage solutions or shipping needs. With minimal wear and tear, they provide excellent durability and reliability, making them a top choice for those seeking the best in performance.
CW (Cargo Worthy): These containers have been inspected and deemed fit for cargo transport. They may have some cosmetic imperfections but are structurally sound and safe for shipping.
WWT (Wind and Watertight): These containers are designed to keep out wind and water. They are ideal for storage and can protect your goods from the elements.
AS-IS Containers: These containers are sold in their current condition, with no guarantees on structural integrity or functionality. They may have severe damage or rust and are typically used for scrap or repurposing projects. As-is containers are ideal for those looking for the lowest price and who are willing to take on a project.






Standard shipping containers are typically available in 20β and 40β lengths, with a height of 8β6β and width of 8β. These dimensions comply with international ISO standards, making them ideal for storage, transport, or modification projects.
Standard containers are well-suited for dry, secure storage of tools, equipment, materials, household goods, business inventory, and more. Theyβre often used at construction sites, residential properties, farms, and commercial facilities.
Yes. Standard containers are among the most modification-friendly models due to their consistent dimensions and steel framing. We commonly install roll-up doors, man doors, windows, insulation, electrical systems, and interior finishing β especially on new or one- trip containers, though select used units may qualify as well.
Shipping containers are engineered with corner castings on all four top and bottom corners, allowing them to be safely stacked and locked together using twist locks. This makes them ideal for projects requiring multi-level storage or modular building layouts.
A permanent foundation is not required for basic use, but we recommend placing
containers on level surfaces such as gravel pads, concrete piers, or timber blocks. This helps ensure proper door function, minimizes corrosion, and supports long-term structural stability.
