Part 01 | What is a shipping container?
Shipping containers are among the most fundamental and essential logistics carriers in modern international trade.
It functions like a “mobile standard shipping container”—after being loaded and sealed at the factory, it’s transported by truck to the port, then loaded onto an ocean-going vessel for delivery worldwide. Along the way, there’s no need to unpack or transship, truly enabling seamless door-to-door logistics.
> Why is container shipping the mainstream mode of global trade?
• High degree of standardization: globally uniform dimensions, universally compatible with any port and shipping line.
• Fast handling efficiency: Mechanized operations significantly reduce port dwell time.
• Stable transportation costs: Bulk loading ensures unit costs remain controllable and predictable.
Part 02 | What are the common cabinet types?
> Additionally, 45HQ and 20FC, 40FR (Framework cabinets), 40RH (refrigerated cabinets), and other specialized container types are available for selection as needed.
Part 03 | The Core of Box Type Selection:
Focus on density, not volume—this is a common pitfall for 90% of newcomers to international trade.
❌Common Misconceptions
> "If there’s a shortage, just place the order." 20GP , if there’s a large quantity, we’ll book a 40GP/40HQ container.
Incorrect. The gold standard for selecting a container type is cargo density, not merely the container’s volume.

> Key reminder: A 20-foot GP container has a maximum payload of approximately 28 tons (subject to the container’s condition and the shipping line’s weight limits), while a 40-foot GP/ 40HQ The weight limit is typically 26–28 tons; loading heavy cargo into a full container results in double waste.
