T-1000 Shipping Container Desiccant Strip | Moisture Control & Mold Prevention
Product Overview
iHeir T-1000 Container Desiccant Bar is a high-capacity calcium chloride desiccant developed for ocean freight, export shipping containers and long-distance cargo transportation. It helps manage moisture inside shipping containers, reducing the risk of condensation, container rain, damp packaging and moisture-related cargo damage.
Formulated with calcium chloride (CaCl2) and moisture-retention materials, T-1000 absorbs water vapor from the surrounding air and retains the collected moisture within its absorbent system. This helps reduce free liquid water and moisture-related packaging problems during transit.
T-1000 is suitable for container shipments of footwear, bags, leather goods, apparel, textiles, furniture, bamboo and wooden products, metal products, medical supplies and medical devices. It provides a practical moisture-control solution for manufacturers, exporters, trading companies and international brands.
For shipments involving extended ocean transit, changing climate conditions or high-humidity destinations, T-1000 provides an additional layer of moisture protection to help preserve cargo and packaging quality.
Why Is Moisture Protection Important for Ocean Freight?
International ocean shipments often take several weeks or longer. Even when products are properly packed and appear to be in excellent condition at the factory, temperature fluctuations and humidity changes during transportation can expose them to moisture-related risks.
One common problem is container rain. When warm, moisture-laden air inside a shipping container comes into contact with cooler metal surfaces, water vapor may condense into droplets. These droplets can accumulate on the container ceiling or walls and eventually drip onto cartons and cargo.
Common Problems Caused by Moisture During Shipping
Effective ocean freight moisture protection should address not only the conditions at loading but also moisture accumulation and condensation risks throughout the shipping journey.
How T-1000 Works: Technology and Key Advantages
T-1000 combines calcium chloride moisture absorption technology with a moisture-retention system. It absorbs water vapor from the air inside shipping containers and helps retain the collected moisture within its absorbent material.
Unlike small desiccant packets typically used in individual product packaging, T-1000 is designed for moisture management in larger cargo spaces, making it suitable for containerized ocean freight and humid transportation environments.
1. High Moisture Absorption Capacity
Its high calcium chloride content provides strong moisture-absorbing performance. According to the technical specifications, T-1000 achieves a moisture absorption capacity of at least 200% of its own weight under test conditions of 25 degrees Celsius and 80% relative humidity.
2. Effective Moisture Retention
The moisture-locking formulation helps retain absorbed water within the material, reducing the risk of free liquid movement or moisture release during transportation.
3. Helps Reduce Container Rain and Condensation
By lowering the amount of water vapor in the container air, T-1000 helps reduce the likelihood of condensation when temperatures fluctuate, protecting cartons and cargo from moisture-related damage.
4. Suitable for Long-Distance Ocean Shipping
Designed for moisture control during international container transportation, including shipping routes with changing temperatures and humidity conditions.
5. Convenient Hanging Design
T-1000 can be hung at suitable locations along the interior walls of shipping containers. It requires no electrical power and can be incorporated into standard factory loading procedures.
6. Versatile Industrial Applications
From footwear, furniture and leather goods to metal products, medical supplies and medical devices, T-1000 supports moisture management across a wide range of export industries.

Frequently Asked Questions
Q1: How many container desiccant bars are needed for a 40-foot shipping container?
The general reference quantity is 8 - 12 T-1000 bars per standard 40-foot container. Actual requirements depend on cargo moisture content, packaging materials, shipping duration, climate and loading conditions.
Q2: Can T-1000 help prevent container rain during ocean shipping?
Yes. By absorbing water vapor from the container air, T-1000 helps reduce humidity and the likelihood of condensation, thereby reducing the risk of container rain and moisture-related cargo damage. Performance depends on the shipping environment, moisture sources and product configuration.
Q3: What is the difference between T-1000 and silica gel desiccants?
T-1000 uses a calcium chloride absorbent system with moisture-retention materials and is intended for large shipping container environments. Silica gel desiccants are more commonly used in smaller packaging applications, such as shoeboxes and electronic product packaging. Their absorption characteristics and intended applications differ.
Q4: Is T-1000 suitable for medical supplies and medical device exports?
Yes. T-1000 can be used for humidity control inside shipping containers transporting medical supplies, medical devices and related packaged products. It helps reduce condensation, container rain and moisture exposure affecting outer shipping cartons. Customers in the medical-related industry are already using T-1000. Suitability should be evaluated against the specific product, packaging design, shipping conditions and applicable quality requirements.
Q5: Is T-1000 suitable for shipments from China, Vietnam and Indonesia?
