Marking of Shipping Containers
Marking of shipping containers plays a crucial role in global logistics. Knowledge of the meaning of individual markings such as MAX. GR, TARE, NET / PAYLOAD, CU. CAP. and prefixes is essential for efficient and safe handling of containers. This information helps transporters, warehouse workers and other logistics professionals ensure that each container is properly loaded, transported and unloaded.
Shipping containers play a crucial role in global goods transportation. To ensure their efficiency and safety, proper marking of each container is essential. Container markings provide important information that helps with handling, storage and transportation. In this article, we will look at the most common markings of shipping containers and what they mean.
MAX. GR = Maximum Load (Maximum Gross Weight)
One of the most important data on a shipping container is the marking MAX. GR or Maximum Gross Weight. This marking indicates the maximum weight of the container including its cargo. It is the total weight that the container can safely transport.
For example, for a 20-foot High Cube container, the maximum load can be up to 30,480 kg. This data may vary depending on the manufacturer and type of container, but generally the maximum weight remains similar across different container sizes.
TARE = Weight of Empty Container
The marking TARE represents the weight of an empty container. This value is important for calculating the total weight when loading cargo. For example, an empty 20-foot container may weigh around 2,040 kg.
The weight of an empty container may vary depending on the manufacturer and specific model, but it always provides a clear idea of the basic weight of the container without cargo.
NET / PAYLOAD = Maximum Cargo Weight
NET or PAYLOAD marking indicates the maximum weight of cargo that can be loaded into the container. This data is key for transporters who need to know how much goods they can safely load.
For example, if a container has a maximum gross weight of 30,480 kg and its empty container weight is 2,040 kg, the maximum cargo weight will be 28,440 kg. Knowing exactly how much cargo can be loaded is essential for efficient and safe transportation.
CU. CAP. = Capacity in Cubic Meters (Cubic Capacity)
The marking CU. CAP. or Cubic Capacity indicates the capacity of the container in cubic meters. This data informs about the internal volume of the container and is important when planning loading, especially for bulky or light cargo.
For example, a 20-foot container may have a capacity of around 33 cubic meters, while a 40-foot container offers up to 67 cubic meters. A larger container provides more internal space, which is advantageous for storing light but bulky goods.
Container Prefixes
Each shipping container also has a unique identification code that begins with a so-called prefix. This code consists of four letters that designate the owner or operator of the container.
For example, the prefix HZKU may designate containers of HZ CONTAINERS s.r.o. company. This identification system is standardized according to international ISO standards, which facilitates tracking and identification of containers worldwide.
Other Markings and Symbols
In addition to the markings mentioned above, containers may carry additional information and symbols. This information may include:
- IMDG Code: Code for the transportation of dangerous materials.
- CSC Plate: Certification plate that confirms that the container meets international safety standards.
- ISO Code: Code that specifies the type and dimensions of the container.
These additional markings provide further information that is important for safe and efficient handling and transportation of containers.
