Container dehumidifier
What is a container dehumidifier?
A container dehumidifier is a specially designed device that absorbs moisture inside shipping containers. This product is essential to protect goods from condensation and consequential damage that can occur during transport or storage.
Why is moisture in the container a problem?
Significant temperature fluctuations can occur when goods are transported in containers. As the temperature drops, the hot air, which may contain more moisture, cools and the moisture condenses. This phenomenon is known as “container rain” or “cargo sweat”. Moisture can cause mould growth, damage to packaging, deterioration of labels and other problems that can significantly affect the quality and integrity of the goods being transported.
How does the container dehumidifier work?
Container dehumidifiers work on the principle of moisture absorption. They are made of materials with high absorption capacity, such as calcium chloride, starch, silica gel or desiccant clay. These materials effectively reduce the relative humidity inside the container and thus prevent condensation.
Types of container dehumidifiers
- Desiccant paws: this is a pack containing desiccant that can be easily placed in a container. They have a high absorption capacity and are available in different sizes and forms.
- CORPAC COR-DRY GEL: This type of dehumidifier combines calcium chloride and starch, allowing it to have extremely high absorption capacity in areas of high humidity. It is ideal for long transport by truck, train or ship.
- Thomar OHG: Specialized desiccant dryers that are designed to operate efficiently even with significant temperature fluctuations during transport and storage.
Advantages of using container dehumidifiers
- Prevents moisture damage: protects goods from unwanted moisture and condensation.
- Prevents mould growth: moisture encourages the growth of mould, which can spoil goods.
- Prevents white rust: Especially on unwrapped zinc or galvanized steel parts.
- Easy handling: the desiccant packs and gel dehumidifiers are easy to use and quick to install.
How to choose the right container dehumidifier
When choosing a container dehumidifier, it is important to consider several factors:
- Length of transport: longer transport requires dehumidifiers with higher absorption capacity.
- Item type: some materials are more sensitive to moisture than others.
- Climatic conditions: transportation through different climatic zones may require special dehumidifiers.

What Is the Shipping Cost for a 40ft High Cube Container?
The shipping cost for a 40ft high cube container is not a single number — it is a layered calculation spanning purchase price, international ocean freight, and local ground delivery. A used 40ft high cube container typically costs $1,550 to $5,500 to purchase, while a new one-trip unit runs $2,800 to $9,000 depending on condition, location, and whether delivery is included.
Shipping container types
Roughly 80% of everything you own traveled to you inside a steel box. Shipping containers—also called cargo containers, ISO containers, or “conex” boxes—are the backbone of global trade, carrying about 90% of the world’s non-bulk cargo across oceans, rails, and highways. Yet a “shipping container” is not one single object. It is a family of specialized steel boxes, each engineered for a specific kind of cargo: some vent, some freeze, some open from the top, and some have no walls at all.
Where Can I Buy a 40ft High Cube Container?
A 40ft high cube container represents one of the most versatile and cost-effective storage and shipping solutions available today. Whether you are expanding warehouse capacity, starting a container home project, or need secure on-site storage for a construction site, knowing where to buy one — and what to expect — can save you thousands of dollars and weeks of frustration. This guide walks you through every aspect of purchasing a 40ft high cube container, from understanding what it actually is to comparing sellers, navigating delivery logistics, and handling permits.
How much does a 40 foot shipping container cost?
A 40 foot shipping container is the single most common large-format steel container in the world. Whether you are adding on-site storage, moving freight overseas, or converting a unit into a home or workshop, the first question almost everyone asks is the same: how much does a 40 foot shipping container cost?
The short answer is that a 40 foot shipping container price in the United States typically lands between $1,500 and $7,000 depending on condition, height, location, and delivery. Used, wind-and-watertight 40ft units often start near $1,500–$2,700, while a brand-new one-trip 40ft high cube can exceed $4,000–$6,500. The gap between those two ends of the range is wide because a “shipping container” is not one product—it is a graded commodity whose value shifts with its physical condition, its market, and even the distance from your site to a major port.
