Shipping container marking 22G2

The designation of shipping containers plays a key role in identifying their parameters, characteristics, and purpose. One of these designations is 22G2, which provides important information about the type, dimensions, and features of a given container. Let’s analyze this designation in more detail and understand its significance in the context of international transportation and goods storage.

What does the code 22G2 indicate?

The code 22G2 is part of a standardized container marking system according to ISO 6346, which is an internationally recognized standard. This standard is used for identifying and categorizing shipping containers. Each code includes a combination of numbers and letters specifying the type, dimensions, and other key characteristics of the container.

  • “22”: The first two digits indicate the size and dimensions of the container. In the case of code 22, it refers to a standard 20-foot container, which means a length of approximately 6.1 meters. This dimension is one of the most common in the transportation industry.
  • “G”: The letter in the code denotes the type of container. The letter “G” in this case indicates that it is a general-purpose container designed for transporting a wide range of goods. This type of container has solid walls, a floor, and a roof, ensuring cargo protection against external influences.
  • “2”: The last digit in the code further specifies the container’s features. For code 22G2, it refers to a standard closed container without special modifications, such as ventilation or insulation.

Key characteristics of the 22G2 container

Containers marked as 22G2 are among the most commonly used containers in freight transportation. Their universal design and standard dimensions make them ideal for a wide range of transportation and storage needs. Below are the key features of these containers:

  1. Standard dimensions
    The 22G2 container has typical dimensions for a 20-foot container: a length of 6.1 meters, a width of 2.44 meters, and a height of 2.59 meters. These dimensions ensure easy handling and compatibility with global transportation systems.
  2. Durable construction
    These containers are made of robust materials, usually Corten steel, which is resistant to corrosion and adverse weather conditions. This makes 22G2 containers suitable for long-term transportation and storage.
  3. Strength and load capacity
    The 22G2 container offers high load capacity, including a maximum gross weight (MAX. GR) that typically reaches up to 30,480 kg. The empty container weight (TARE) is around 2,200 kg, meaning the maximum cargo weight (NET/PAYLOAD) is approximately 28,280 kg.
  4. Versatile use
    Thanks to their design, 22G2 containers are suitable for transporting and storing various types of goods, including consumer goods, industrial products, raw materials, and smaller machinery. The closed construction protects the cargo from moisture, dust, and other external factors.

The Role of Marking in Logistics and Transportation

Markings, such as 22G2, are crucial for the efficient management of international transport and logistics. This marking enables easy identification of the container type, its parameters, and features. Thanks to standardization, transport companies, warehouses, and customs offices can quickly recognize the type of container they are dealing with, speeding up the entire process of handling and processing goods.

For example, workers at ports or terminals can immediately determine, based on the marking, whether a container is compatible with their handling equipment and what type of goods it may contain. Similarly, customers and carriers can choose the appropriate container type for their transport needs based on the markings.

The Difference Between 22G2 and Other Container Types

Containers marked as 22G2 are classified as standard general-purpose containers. In contrast, there are other types of containers designed for specific purposes, such as:

  • Ventilated containers (e.g., 22V2), which have ventilation openings for better air circulation, making them ideal for transporting goods sensitive to moisture.
  • Insulated containers (e.g., 22R1), which are equipped with insulating materials for transporting temperature-sensitive goods.
  • Flat rack containers (e.g., 22PC), which have an open design and are intended for transporting oversized or irregularly shaped cargo.

Each container type has its specific marking, which facilitates its identification and ensures that it is used for the correct purposes.

The 22G2 shipping container marking represents a standard 20-foot general-purpose container, which is ideal for transporting and storing a wide range of goods. Thanks to its robust construction, universal dimensions, and high load capacity, these containers are among the most commonly used in international transport. Standardized markings, such as 22G2, play a key role in efficient logistics, as they allow for the quick and accurate identification of a container and its features.
