Looking for reliable container moisture protection solutions, shipping containers for sale, or container parts? CIMC Equilink solves condensation issues in shipping—protecting your cargo with professional desiccant strategies. Below’s a real case study of how we helped a customer safeguard plant seeds during transit from China to Germany.  

Customer Pain Point: Container Condensation Risks

A customer used our 20-foot dry container to ship plant seeds (in three-layer composite bags) from Tianjin Port to Hamburg, Germany. For years, they used 4-6 pieces of 1.4kg calcium chloride desiccant per 20ft container. However, starting in January 2020, condensation appeared:  

• Water droplets on container steel plates (causing rust).  

• Condensation on product packaging in the container’s middle.  

• Hidden safety risks for the moisture-sensitive seeds.  

They turned to CIMC Equilink’s professional logistics team for a solution.  

Case Analysis: Why Condensation Happened

1. Temperature Fluctuations: From January to March, Germany’s low temperatures clashed with the container’s journey through warm regions (South China Sea, Indian Ocean, Mediterranean). This sharp temperature drop triggered condensation.  

2. Insufficient Desiccant: The calcium chloride desiccant dosage (designed for summer) was inadequate for harsh winter conditions.  

3. Uneven Placement: Desiccant hung on sidewall grooves didn’t reach the container top or middle cargo areas, leaving those zones unprotected.  

4. Blocked Moisture Absorption: Cardboard on the container’s inner wall blocked the desiccant’s moisture absorption holes, reducing effectiveness.  

Dry Container Moisture Protection Solutions

We developed three targeted strategies to resolve the issue:  

1. Adjust Desiccant Dosage

• Winter (Oct–Mar loading): Increase to 8 pieces of 1.4kg calcium chloride desiccant per 20ft container.  

• Summer (Apr–Sep loading): Maintain 6 pieces per 20ft container.  

• Note: This works only if the desiccant can absorb moisture effectively under the existing loading method.  

2. Switch to Wisecargo 125g Container Desiccant

For comprehensive, even humidity control, replace calcium chloride desiccant with Wisecargo 125g desiccant (distributed throughout the container):  

• Winter (Oct–Mar): 36 packs per 20ft container.  

• Summer (Apr–Sep): 32 packs per 20ft container.  

This solution ensures every area of the container is protected, eliminating blind spots.  

3. Comparative Test for Effectiveness

To verify the new desiccant’s performance, we designed a side-by-side test:  

• Test Setup: Two containers shipping the same goods to Hamburg, with identical packaging.  

￮ Container 1: 6 pieces of 1.4kg calcium chloride desiccant (sidewall-hung).  

￮ Container 2: 32 packs of 125g Wisecargo desiccant (distributed evenly).  

• Data Collection: Place two temperature-humidity recorders in each container (one inside product packaging, one outside) – positioned away from desiccant to ensure accuracy.  

• Evaluation: Document the test with photos, then send recorders and data to a professional agency recommended by CIMC Equilink for analysis.  

Test Results & Customer Feedback

The evaluation agency issued a detailed report confirming that Wisecargo 125g desiccant effectively controlled humidity throughout the container, eliminating condensation. The customer praised our professional solutions and continued to partner with us.
