1.Why Moisture Is a Major Problem in Container Shipping
During long-distance shipping, especially over oceans, containers are exposed to extreme temperature and humidity fluctuations.These conditions lead to container rain—when condensation forms on the inner walls and ceiling of containers and drips onto goods, causing mold, corrosion, packaging damage, and loss of value.
2.What Are Container Desiccants?
Container desiccants are moisture-absorbing products specifically designed for large-scale cargo shipments.They help stabilize humidity levels inside the container and prevent condensation by absorbing excess moisture from the air.
3.Common Types of Container Desiccants
Calcium Chloride
High moisture absorption capacity (up to 300% of its own weight), ideal for sea freight.
Clay + Calcium Chloride Blends
Offers balanced performance and cost-effectiveness.
Silica Gel
Used for specific goods like electronics or textiles with low humidity tolerance.
4.How to Use Container Desiccants Properly
Placement: Hang or place desiccants along container walls or within cargo pallets.
Dosage: Use 1–2kg per 20ft container depending on cargo type and route.
Packaging: Most come in strip bags, pole types, or large hanging packs.
Duration: Designed to last 30–90 days depending on the product.
5.Industries That Rely on Container Desiccants
Automotive Parts
Prevents rust and corrosion on metal components.
Agricultural Products
Keeps grains, spices, and seeds dry during shipping.
Textiles & Leather
Prevents mildew and musty odors.
Electronics
Protects sensitive devices from moisture damage.
Furniture & Wood
Reduces the risk of mold, swelling, or paint damage.
6.Benefits of Using Container Desiccants
✅ Prevents container rain and moisture damage
✅ Reduces product returns and claims
✅ Protects brand reputation and customer trust
✅ Cost-effective for international logistics
✅ Easy to apply, no power or maintenance required
7.Conclusion: Keep Your Cargo Dry and Safe
Investing in high-quality container desiccants is a small cost compared to the losses caused by moisture damage.Whether you’re exporting electronics, textiles, grains, or machinery, using the right desiccant helps ensure your cargo arrives in perfect condition.
