When buying a shipping container, one of the first things you’ll come across is the term “container grades.” These grades are an industry standard used to describe the condition and quality of a container, ranging from like-new to heavily used. At the same time, you’ll also need to decide between new (also called one-trip) and used options, which affects both price and performance.
In this guide, we’ll explain what container grades mean, the differences between new/one-trip and used shipping containers, and how options like refurbished, Grade A, B, or C units fit into your decision. By understanding these classifications, you can choose the right container for your budget, storage needs, or shipping requirements.
Types of Shipping Containers: New vs. Used Options
New Shipping Containers
New shipping containers—commonly referred to as one-trip containers—are built to be structurally sound and free from dents or rust. After leaving the factory, they are usually loaded with cargo once (a “one trip”) to cover shipping costs before being sold. This is why “new” and “one-trip” are used interchangeably in the industry.
These containers offer maximum durability and typically arrive in pristine condition, making them an excellent choice for secure, long-term storage. One-trip containers are also ideal for transporting cargo across oceans without compromising on quality.
Used Shipping Containers
Used shipping containers come in a range of conditions that affect their usability and price. While they can be a cost-effective choice, it’s important to inspect them for rust, dents, and structural issues. Grades such as B or C containers are available at different price points, making it easier to balance budget with functionality.
Refurbished Containers
Refurbished containers provide a middle ground between new and used. These units are inspected, repaired, and certified to meet standards, ensuring they are wind and watertight (WWT). They offer an affordable yet reliable option for storage or shipping, but it’s still crucial to verify their condition before purchase.
Understanding Container Grades
Grade A Containers
Grade A containers are in excellent condition with minimal wear. They are often new or like-new, making them ideal for international shipping or secure storage. Their structural integrity ensures safe transport without risk of wind or water damage.
Grade B Containers
Grade B containers remain cargo-worthy but may show minor dents or surface rust. While not as pristine as Grade A, they are durable, reliable, and more budget-friendly, offering good value for many shipping and storage applications.
Grade C Containers
Grade C containers display significant wear, including rust or structural issues. They are typically sold as-is and may not meet cargo-worthy standards without repairs. Although the most affordable option, they require careful inspection and potential refurbishment.
Choosing the Right Container for Your Needs
Assessing Your Requirements
Before selecting a container, assess your purpose and budget. Decide whether you need it for storage or international shipping, and consider factors such as size, grade, and expected lifespan. This evaluation will help you select the best option for your specific situation.
Inspecting Before Purchase
Whether new or used, inspection is essential. Look for rust, dents, or other damage that could affect performance. Ensure the unit is wind and watertight (WWT) to protect your cargo or belongings.
Buying Containers Online
Purchasing containers online can be convenient, but always choose a reputable supplier. Research the company, check reviews, and confirm their inspection and certification process. These steps help ensure you receive a quality product that fits your budget.
Conclusion
Understanding shipping container grades—and the differences between new, used, and refurbished options—helps you make a confident, cost-effective choice.
