BIC – Bureau International des Containers
Bureau International des Containers (BIC), known in English as International Container Bureau, plays a key role in the global shipping industry. Founded in 1933, this organization was instrumental in standardizing and streamlining the containerization process, which is the method of using standardized shipping containers for transporting goods. This glossary page aims to provide a comprehensive understanding of BIC, its functions, and the importance of container identification in international transport.
Bureau International des Containers (BIC) and its coding system are indispensable for the modern shipping industry. By providing a global standard for container identification, BIC increases the efficiency, safety, and reliability of international trade. Understanding BIC codes and their application is key for anyone involved in logistics and maritime transport, as these codes form the basis for managing and transporting containers.
What is BIC?
Bureau International des Containers (BIC) is an international organization responsible for the oversight and registration of intermodal shipping containers. It serves as the authoritative body for establishing and maintaining standards for container identification, particularly through BIC codes. This coding system is essential for ensuring smooth movement and tracking of containers across global supply chains.
Historical Context
BIC was founded in 1933 under the auspices of the International Chamber of Commerce with the aim of promoting cooperation between businesses, governments, and independent organizations involved in intermodal cargo transport. The disruption of World War II halted its operations, but in 1948 it resumed operations and continued its mission to standardize container use at the international level. The introduction of ISO standard 6346, a standard for container identification and coding, in 1970 was a significant milestone in BIC’s history, further solidifying its role in the global logistics industry.
The organization initially aimed to establish mandatory parameters for containers used in international transport, particularly in Europe. This included specifications regarding the weight and type of containers, such as whether they are open or closed, and whether they are classified as heavy or light types. Early BIC regulations laid the foundation for what became modern intermodal cargo transport.

Role and Functions of BIC
The primary function of BIC is to maintain an international registry of container owner codes, known as BIC codes. These codes are key for:
- Identification: They enable unique identification of container owners and operators.
- Tracking: They enable tracking of containers throughout the transport chain.
- Standardization: They support uniformity in container marking, which helps with customs and logistics operations.
BIC collaborates with the International Organization for Standardization (ISO) to ensure that container codes and markings meet global standards, thereby facilitating international trade and logistics.
Key Terms
BIC Codes
BIC codes are a standardized system for identifying shipping containers. They consist of:
- Owner Code: A three-letter prefix representing the owner or operator of the container.
- Equipment Identifier: The fourth letter indicating the type of equipment (U for containers, J for removable equipment, Z for trailers).
- Serial Number: A unique six-digit number assigned by the container owner.
- Check Digit: A single-digit number used to verify the correctness of the container code.
Significance of BIC Codes
- Global Standardization: BIC codes are recognized globally, ensuring that containers comply with international regulations and can move across borders.
- Operational Efficiency: These codes help in efficient management of container fleets by providing important information about the owner, type, and specifications of the container.
- Safety and Compliance: The use of standardized codes helps maintain safety and compliance with international shipping laws and customs regulations.
Shipping Containers and Their Identification
Shipping containers, the backbone of international trade, are identified using a unique combination of letters and numbers. This identification system is key for managing the logistics and operations associated with transporting goods worldwide.
Components of Container Number
- Owner Prefix: The first three letters indicating the container owner.
- Category Identifier: The fourth letter indicating the type of equipment.
- Serial Number: A six-digit unique identifier.
- Check Digit: Used to verify the entire container number.
Mandatory Operational Markings
In addition to the container number, shipping containers have operational markings that provide basic information:
- Maximum Gross Weight: The heaviest the container can be when loaded.
- Tare Weight: The weight of an empty container.
- Payload: The maximum weight of goods the container can transport.
International Registry of Container Owner Codes
BIC maintains this registry, which is key for identifying and verifying container ownership at the global level. This registry helps prevent code duplication and ensures that each container can be reliably tracked and managed.

International Organization for Standardization (ISO)
ISO is a key partner of BIC, particularly in the development of ISO standard 6346. This partnership ensures that container identification complies with globally recognized standards, promoting interoperability and efficiency in international transport.
Customs Convention on Containers
This international convention, which references ISO standard 6346, facilitates the free movement of containers worldwide by standardizing regulations and procedures.
Container Tracking
Container tracking, enabled by BIC codes, allows shippers and logistics providers to monitor the location and condition of containers in real time. This capability is essential for optimizing supply chain operations and reducing costs associated with delays and inefficiencies.
