In the world of international logistics, container standardization has revolutionized maritime transportation. GLOBAL AF LOGISTICS, with extensive experience in organizing containerized transport, presents a comprehensive guide to maritime container dimensions and characteristics that will help you choose the optimal solution for your cargo.
History of Container Standardization
The modern containerization system was revolutionized in the 1950s by American entrepreneur Malcolm McLean. The International Organization for Standardization (ISO) established uniform standards that are used worldwide today. GLOBAL AF LOGISTICS works exclusively with ISO-certified containers, guaranteeing compliance with all international safety and quality requirements.

Specialized Containers
Open Top Containers
Open-top containers are designed for cargo that cannot be loaded through standard doors. GLOBAL AF LOGISTICS organizes oversized cargo transportation using specialized equipment for top loading.
Flat Rack Containers
Platform containers without side walls or roof are used for transporting heavy machinery, large diameter pipes, and other oversized cargo.
Refrigerated Containers (Reefer)
Equipped with cooling and temperature maintenance systems from -30°C to +30°C. Ideal for transporting perishable products, pharmaceuticals, and chemicals.
Container Size Selection Factors
When choosing optimal container size, GLOBAL AF LOGISTICS considers the following factors:
Cargo Volume-Weight Characteristics
The ratio between cargo weight and volume determines the most economical container choice. Light, voluminous cargo requires high-volume containers, while heavy, compact cargo requires high-capacity containers.
Packaging Particularities
Package unit dimensions and shapes affect the efficiency of container internal space utilization. Our specialists perform optimal loading calculations to minimize empty space.
Delivery Route
Different ports and rail terminals may have container size restrictions. GLOBAL AF LOGISTICS considers all route particularities when planning transportation.
Transportation Cost
Maritime freight rates are usually calculated per container, regardless of loading degree. Loading optimization allows significant reduction in unit transportation costs.
Technical Loading Aspects
Weight Distribution
Proper weight distribution inside the container is critically important for transportation safety. GLOBAL AF LOGISTICS uses specialized software for calculating optimal cargo placement.
Cargo Securing
All cargo must be securely fastened inside the container using certified securing materials. Our specialists ensure compliance with all IMO (International Maritime Organization) requirements.
Marking and Documentation
Each container must be properly marked indicating contents, weight, special handling requirements, and contact information.
Economic Aspects
Correct container size selection can substantially impact total logistics operation costs. GLOBAL AF LOGISTICS conducts detailed analysis of all costs, including:
- Maritime freight costs
- Port charges and handling
- Inland transportation
- Cargo insurance
- Customs procedures
