Understanding Container ISO Codes
Container ISO codes play a crucial role in global shipping logistics. At Shipping Containers of Manchester, we ensure all our containers meet the strict ISO standards for safe, efficient, and compliant transport worldwide.
What is a Container ISO Code?
An ISO code is a unique identifier assigned to shipping containers based on the International Standard ISO 6346. It standardises container identification globally, helping logistics professionals easily and accurately track, monitor, and manage containers across borders.
Why are ISO Container Codes Important?
- Global Uniformity: ISO codes create a universal language for ports, shipping lines, and customs authorities.
- Enhanced Efficiency: They simplify tracking, logistics management, and operational safety during shipping and storage.
- Improved Safety: ISO codes specify container type, size, and weight limits, ensuring cargo safety and preventing overloading.
- Regulatory Compliance: Containers with correct ISO markings meet international shipping and customs regulations, avoiding costly delays or fines.
How are ISO Container Codes Structured?
Each ISO container number includes:
- Owner Code: A three-letter code identifying the container’s owner.
- Equipment Category Identifier: Usually 'U' for freight containers.
- Serial Number: A unique six-digit number for tracking.
- Check Digit: A single digit used to validate the container number.
Example: MSCU 123456 7 — where MSC is the owner, U identifies a freight container, 123456 is the serial number, and 7 is the check digit.
Common ISO Codes for Container Types
- Dry Storage Containers: 22g1 / 22g0 — general cargo containers.
- High Cube Containers: 45g1 — extra height for bulky goods.
- Reefer Containers: 45r1 — refrigerated units for perishable cargo.
- Open Top Containers: 22u1 — ideal for oversized cargo.
- Tank Containers: 22t1 — for transporting liquids and gases.
Where to Find the ISO Code on a Container
The ISO code is displayed on the exterior of the container, typically on the doors and side panels, to allow easy identification during transport and inspection.
