How to get rid of moisture in a shipping container
Moisture in a shipping container can cause significant problems such as condensation, corrosion and damage to the cargo. It is important to control humidity properly to avoid these complications. Here are some tips and tricks to effectively get rid of moisture in a shipping container.
Why does condensation occur in the container?
Condensation in the container is mainly caused by temperature fluctuations. During transport and storage, temperatures inside the container can change significantly, leading to condensation. Warm air can absorb more moisture than cold air, and when the temperature drops, the moisture precipitates as water droplets. This phenomenon is known as “container rain” or “container sweat”.
What are the options to control humidity in the container?
1. Using a dehumidifier
Dehumidifiers are specially designed devices that absorb moisture from the environment inside the container. There are different types of dehumidifiers that can be used:
- Absorption dehumidifiers: These dehumidifiers work on the principle of moisture absorption using a specific medium that draws moisture from the surrounding air.
- Electric dehumidifiers: they require an external power source but are very effective in reducing humidity.
2. Ventilation
Proper ventilation can significantly reduce humidity inside the container. Ensure that air can circulate freely to help remove excess moisture.
3. Use of moisture barriers
Moisture barriers, such as plastic sheeting or special coatings, can help prevent moisture from entering the container.
4. Regular inspection
Check the condition of the container and cargo regularly. Look for signs of moisture or condensation and intervene early to prevent damage.
How to use a dehumidifier correctly?
Using a dehumidifier is a simple but effective solution. Here’s how to use it properly:
- Remove the plastic wrap: Before using the dehumidifier, remove its plastic packaging.
- Attach the hook: Attach the hook to the top of the container’s protective cover.
- Hang the dehumidifier: hang it by the fastening ring inside the container.
The dehumidifier immediately starts working on the principle of moisture absorption, thereby reducing the relative humidity inside the container.
Other recommendations
- Proper packing of cargo: Use moisture barriers and packaging that protects cargo from moisture.
- Container location: if possible, place the container in a dry and well-ventilated place.
- Monitoring conditions: Use hygrometers and thermometers to monitor conditions inside the container.

The OPNBar leverage tool
The OPNBar leverage tool is a professional-grade, multi-purpose hand tool designed specifically for the shipping container and trucking industry. Manufactured by Shipping Container Safety International (SCS International) and proudly Made in the USA, the OPNBar is fundamentally a 3-in-1 trucker tool that combines a shipping container door leverage bar, a tire thumper, and a 5th wheel pull hook into a single, compact steel implement. The name “OPNBar” is a direct reference to its primary function: it is the bar that “opens” containers.
40 Foot Container Dimensions
If you have ever booked ocean freight, planned a warehouse layout, or designed a modular building project, you have asked the same question: what are the exact 40 foot container dimensions — and what do they mean for what you can actually load? The numbers are standardized worldwide, but the practical implications of those numbers are surprisingly nuanced. A 40-foot container is not simply 40 feet of usable space, and its weight limits are not what most people assume. This guide covers every measurement, every weight rating, and every loading consideration you need to make informed decisions about the world’s most common shipping container.
Quick Answer: A standard ISO 40-foot shipping container measures 12.19 m (40 ft) long × 2.44 m (8 ft) wide × 2.59 m (8 ft 6 in) high externally and provides approximately 67.7 m³ (2,390 ft³) of usable internal volume. The maximum gross weight is 30,480 kg (67,200 lbs), with a typical payload capacity of approximately 26,700–26,800 kg (58,900–59,000 lbs).
Shipping container wheels
Moving a 12-meter-long steel box that weighs up to 67,200 pounds was, for decades, exclusively a job for a crane and a licensed operator. That reality has changed. Shipping container wheels — an umbrella term covering a family of mobility solutions — now let a single person reposition a 20ft or 40ft container across a yard, warehouse, or construction site without calling in heavy equipment. This guide covers every aspect of container wheel systems: what they are, how they work, the types available, what they cost, and how to choose the right kit for your container.
Can You Modify a 40ft High Cube Container?
The short answer is yes — you absolutely can modify a 40ft high cube container, and it is one of the most popular container types for modification projects worldwide. But the real question is not whether you can modify one; it is how to do it correctly, safely, legally, and within budget. This guide answers every dimension of that question, drawing on engineering principles, real-world pricing data, and the collective experience of thousands of modified container projects.
Key Takeaway: A 40ft high cube container offers 320 square feet of floor space with an extra foot of ceiling height compared to a standard container — making it the ideal canvas for offices, workshops, homes, retail spaces, and industrial applications. The extra height is particularly valuable when you add insulation and still want comfortable headroom.
