Typical Temperature Inside a Standard Shipping Container

Typical Temperature Inside a Standard Shipping Container

1. What is the typical temperature range inside a standard container?

The internal temperature of a standard dry container can be affected by several factors:

• Ambient temperature: Hot summers and cold winters both have a direct impact on the temperature inside the container.
• Type of cargo: Heat-generating cargo can accelerate temperature changes inside the container.
• Shipping route: Routes that pass through equatorial or polar regions tend to cause larger temperature variations.
• Container material and insulation: Different container materials and structures offer different levels of heat insulation.

Under direct sunlight, the temperature inside a container can be 20°C or more higher than the outside air temperature.

In cold environments, the temperature inside the container may approach the outside temperature, especially over longer transit times.

2. How does internal container temperature affect cargo quality?

• High temperatures may cause certain products to deteriorate, melt, deform, or lose quality.
• Low temperatures may freeze or damage products that are not resistant to cold.
• It is important to understand the temperature tolerance range of each product and choose a suitable container type accordingly (e.g., dry container vs. reefer container).

3. How can you monitor container temperature?

• Use temperature monitoring devices or data loggers placed inside the container to record temperature changes during the journey.
• Some smart containers are equipped with remote monitoring systems, allowing you to view real-time or historical temperature data through a platform or app.

4. Which types of cargo require special attention to container temperature?

• Cargo requiring refrigeration or freezing
  • Examples: food, pharmaceuticals, chemicals, and other temperature-sensitive products.
  • These require refrigerated (reefer) containers or freezer containers with precise temperature control.
• Cargo sensitive to heat or cold
  • Examples: electronic products, precision instruments, artworks, high-value equipment.
  • Excessive heat or cold can cause malfunction, cracking, warping, condensation, or long-term damage.
• Easily flammable or volatile cargo
  • Examples: certain chemicals, solvents, paints, and fuels.
  • High temperatures may lead to accelerated evaporation, pressure build-up, or even fire/explosion risk.

For these types of cargo, temperature control and monitoring are critical.

5. Are there special containers designed for temperature control?

Yes. In addition to standard dry containers, there are:

• Reefer containers (refrigerated or frozen containers):

Designed for precise temperature control, suitable for cargo that needs to be kept chilled or frozen.

• Insulated containers or thermal containers:

These help reduce the impact of external temperature and protect cargo from getting too hot or too cold.

6. How can you reduce the impact of temperature fluctuations during transport?

• Choose the right container type
  • Reefer container: For cargo that requires accurate temperature control.
  • Freezer container: For products that must be kept at low temperatures.
  • Containers with better insulation or special lining: To reduce heat transfer and temperature swings.
• Enhance cargo packaging
  • Use insulating materials (such as thermal blankets, foam, or liners) for sensitive cargo.
  • Avoid placing cargo directly against the container walls, where temperature changes are more extreme.
• Monitor container temperature
  • Use temperature data loggers to record and review temperature during the entire transport period.
  • For high-value or highly sensitive shipments, consider real-time monitoring solutions.
• Choose a reliable transport provider
  • Understand the carrier’s experience and capability in temperature control.
  • Communicate all special temperature requirements clearly before shipping.

Different types of cargo have different temperature needs. Always discuss requirements in detail with your logistics or transport provider before shipment.

To protect your goods, it is recommended to work with an experienced container transport company that understands both operational efficiency and cargo protection.
