Moisture can destroy containerized cargo. About 10% of all container shipments become unusable from moisture damage. The financial impact affects 5% of global merchandise during shipping. Anyone shipping goods through different climate zones needs to understand these risks.
Most people think seawater leaks are the biggest threat. The truth is different. Moisture already exists in the air, cargo, and packaging materials. Temperature changes create condensation as containers move between climate zones. This leads to devastating damage.
Businesses lose millions of dollars each year to moisture damage. Food, electronics, chemicals, pharmaceuticals, construction materials, and textiles suffer the most. High humidity can cause permanent damage during long shipping times.
Shipping containers have metal structures that react quickly to temperature changes. Their walls can heat up to 60°C in daylight and freeze at night. These conditions create the perfect environment for moisture problems.
Moisture wreaks havoc in several ways:
Surface rust can appear on metals at just 40% relative humidity. Mold and mildew thrive when levels exceed 60-70%.
Condensation appears in three main patterns:
Container rain happens when moisture builds up on the ceiling and drips onto cargo. A temperature drop of just 4.4-5.5°C (8-10°F) in the container’s surface can trigger this.
Container sweat forms on interior surfaces when walls cool below the dew point. Rapid cooling, especially at night, often causes this issue.
Cargo sweat appears on the goods themselves. This happens most often when cargo moves from cold to warm environments because air heats up faster than goods.
Day and night cycles make things worse. Heat pushes air out while cooling pulls humid air in. Standard containers only have small ventilation holes. These don’t allow proper air exchange, so moisture stays trapped and keeps condensing during temperature changes.

Desiccants are powerful allies that fight moisture in the shipping industry. These specialized substances protect your valuable cargo from humidity damage during transit.
Shipping container desiccant packs are materials that curb humidity inside shipping containers. These protective agents come as bags, strips, and blankets filled with absorbent materials like calcium chloride, silica gel, or activated clay. Their main goal is simple yet vital – they shield moisture-sensitive goods during storage or transportation. This protection prevents condensation, which people often call “container rain”. Your product’s quality and safety stay intact throughout the shipping process.
Each shipping container desiccant type employs unique moisture-capturing mechanisms. Silica gel captures water molecules through adsorption. The molecules stick to its highly porous surface instead of dissolving into it. This common desiccant can absorb about 40% of its own weight in moisture. Calcium chloride works differently and is the heavy-duty option. It absorbs up to 300% of its weight in water. Desiccants made with a calcium chloride and clay mix typically absorb around 100% of their own weight.
The best desiccants turn absorbed moisture into gel with binding agents. This prevents any leakage risks that could harm your cargo. Without this gel conversion, moisture stays as liquid and could create hazards if the container desiccant breaks during shipping.
Shipping container desiccant bags work best:
The most effective way to use desiccant bags is to place them strategically. Hang them from container ceilings or upper side walls where condensation forms naturally. Buy shipping container desiccant at ftshippingcontainers.com with free shipping worldwide.
The right moisture protection solution depends on understanding five main types of shipping container desiccants available today.
Silica gel remains a popular choice for commercial shipping desiccants. These small, porous beads capture moisture through adsorption on their surface area. The material can absorb approximately 40% of its weight in water vapor. This makes it perfect to protect electronics, pharmaceuticals, and food during transport. Some varieties even change color after saturation, which helps users know the right time to replace them.
Calcium chloride desiccants lead the pack for heavy-duty moisture protection. These powerful absorbers can capture an impressive 300% of their weight in water, which puts them ahead of other desiccant types. They turn absorbed moisture into a gel that prevents leakage. The material works great in high-humidity environments and protects cargo for 60-90 days without interruption.
Molecular sieve desiccants shine in specialized shipping situations. These synthetic zeolites absorb moisture at very low humidity levels thanks to their uniform crystalline structure. They work well in temperatures from -100°C to +300°C, which makes them perfect for temperature-sensitive cargo. Unlike other options, molecular sieves keep working without releasing moisture back as temperatures change.
Activated carbon desiccants do more than control moisture – they eliminate odors too. This two-in-one solution filters impurities from the container environment. Your shipped goods stay protected both physically and maintain their sensory qualities. The material excels at drying gasses and cleaning the air inside shipping containers.
Bentonite clay desiccants give you a cost-effective solution for standard shipping needs. These natural minerals absorb about 28% of their weight in water vapor. They work well at normal temperature and humidity levels. The production process needs no harsh chemicals, which makes clay desiccants an environmentally responsible choice compared to synthetic options.

You can’t use the same moisture protection for every shipment. The best way to keep your cargo safe involves looking at several key factors.
Your cargo’s sensitivity to moisture should guide your choice of desiccant. Electronics, pharmaceuticals, and food products just need strict moisture control. Silica gel desiccants work best for these sensitive items. In spite of that, machinery and metal parts do well with calcium chloride desiccants that can absorb a remarkable 300% of their weight in moisture. Cocoa beans and other agricultural products create special challenges because they release moisture during shipping. Clay-based options are affordable and work well enough for less sensitive items or areas with lower humidity.
Your container’s size plays a big role in how much desiccant you’ll need. More air space in larger containers means more moisture can build up. Routes that pass through different climates or humid regions work better with reliable options like calcium chloride-based desiccants. Short trips might need less protection, but long hauls through multiple climate zones need desiccants that last the whole trip. That’s why you should measure your container’s internal dimensions to figure out the right amount of desiccant.
The right desiccant choice is cheap insurance against moisture damage. It helps maintain product quality and prevents customer returns. Buy shipping container desiccant at ftshippingcontainers.com with free shipping worldwide.
