Container grade

What are the different shipping container grades?

Shipping containers are graded based on their condition, durability, and suitability for transporting goods. The primary container grades are Grade A (Cargo Worthy), Grade B (Wind and Watertight), and Grade C (As-Is). These grades help shippers determine the container's ability to safely transport goods and whether it meets international shipping standards. The classification is important for choosing the right container based on the type of cargo and the specific requirements of the journey, ensuring the protection of goods during transport.

What is the difference between shipping container grades?

The key differences between shipping container grades lie in their structural integrity and suitability for transporting goods. Grade A containers are fully compliant with international shipping standards and can carry sensitive or high-value cargo. Grade B containers, while still functional, are more suited for goods that don’t require pristine conditions, making them a more affordable choice. Grade C containers, being in poor condition, are generally used for storage or non-sensitive cargo. Understanding these differences helps shippers select the right container for their specific cargo needs.

Who is responsible for grading containers?

The responsibility for grading shipping containers typically falls on certified inspectors or container surveyors employed by independent survey companies, shipping lines, or leasing companies. These professionals assess containers based on international standards, such as those set by the International Convention for Safe Containers (CSC), which regulates the structural integrity of containers. Surveyors examine the condition of the container's structure, doors, seals, and surface, assigning grades based on their findings. Container leasing companies and repair depots also play a role in container grading when refurbishing or repurposing containers for transport or storage.

What can be transported in Grade A shipping containers?

Grade A shipping containers, also known as Cargo Worthy containers, are in excellent condition and meet all structural and safety standards for international shipping. These containers can carry a wide range of goods, including sensitive or high-value items like electronics, pharmaceuticals, or machinery. Because they are fully sealed, structurally sound, and meet stringent shipping requirements, they are suitable for transporting goods that require extra protection against damage, weather, or contamination.

What can be transported in Grade B shipping containers?

Grade B shipping containers, often called Wind and Watertight containers, are structurally sound but may show signs of wear, such as surface rust or minor dents. They are still suitable for transporting most types of goods, particularly non-perishable items like furniture, textiles, or bulk materials. Grade B containers are commonly used for short-haul shipments or for storing goods where minor cosmetic damage to the container doesn’t affect the cargo inside. These containers are a cost-effective option for many shippers.

What can be transported in Grade C shipping containers?

Grade C shipping containers, also referred to as As-Is containers, are typically used for storage rather than transport. They may have significant wear, including holes, rust, or damaged doors, making them unsuitable for shipping cargo in most cases. However, they can be used for non-critical storage solutions or for transporting goods that are not sensitive to environmental exposure, such as scrap materials or non-perishable bulk items. Shippers often use these containers for on-site storage or temporary housing.
