We compared five suppliers for shipping and storage, looking at product formats, placement and buying support. This is a desk-researched shortlist, not a hands-on test, and Super Dry is our top pick.
Temperature changes can cause container rain, condensation that forms inside a container and drips onto goods. Start by deciding whether you need protection around the load, inside individual packages, or both.
Key Takeaways
- Super Dry is our top pick for container units, in-box desiccants and optional SD+ consultancy.
- Absortech offers vertical collectors, horizontal blankets and flat sheets.
- Clariant has separate cargo and small-packet ranges.
- Cordstrap publishes a four-step advice and training process.
- TROPACK specifies its container-bag materials and hanging options.
How We Picked
We reviewed manufacturer specifications and published company or partner evidence. For readers comparing the best container desiccant companies, our criteria were application fit, installation, support and buying clarity. We did not test products or measure absorption.
Fit for the Shipment
We compared container and package applications, placement options and handling details. Manufacturer performance claims are not independent comparisons, and customer counts or awards do not establish better moisture protection.
Buying Clarity
For every supplier, ask about quantity, shipping charges, availability, minimum order and recommended placement. Include cargo, packaging, route and trip length so the supplier can explain its recommendation.
1. Super Dry
Super Dry Pros
- Calcium chloride and starch formula that turns absorbed moisture into a contained gel
- Stated absorption of more than 300% of dry weight for up to 90 days
- Stated working range of -5°C to +90°C
- Container units plus in-box desiccants for cartons and product packaging
- Optional SD+ consultancy covering moisture-prevention steps from factory to customer
Super Dry Cons
- No public price was shown on the reviewed pages
- Performance figures come from the manufacturer, not an independent comparison
Why We Picked Super Dry
Super Dry International is the first supplier we would call because it covers both container protection and the cartons inside. Its optional SD+ consultancy also makes it a practical starting point for a small importer reviewing moisture risks along the supply chain.
Among the top 10 desiccant companies buyers tend to shortlist, Super Dry stands out for a calcium chloride and starch formula that turns absorbed moisture into a contained gel. The company says its desiccants absorb more than 300% of their dry weight for up to 90 days, figures that come from the manufacturer rather than an independent test.
Super Dry Pricing
No public price was shown on the reviewed pages. Request a written quote covering product sizes, quantity, shipping charges, availability, minimum order, placement advice and any SD+ consultancy. Judge potential value by the products and support included, rather than an assumed low price.
2. Absortech
Absortech Pros
- Absorpole collector design that traps absorbed moisture as brine, with a recycled-plastic case
- Vertical collectors and horizontal AbsorGel Blanket formats
- Flat AbsorGel Sheet format alongside its hanging units
Absortech Cons
- Installation needs checking: AbsorGel Hanging needs 25 mm of space between the cargo and the unit
- No public price was shown on the reviewed pages
Why We Picked Absortech
Absortech says it runs a strong in-house R&D function. We placed it second for its placement choices, from vertical collectors to blankets and sheets. Match the format to the available space before ordering.
Absortech states that its AbsorGel Pouch-X 125 g has a carbon footprint of 0.091 kg CO₂ per pouch, verified by an accredited third-party institute. This is a sustainability figure, not a measure of moisture protection.

3. Clariant
Clariant Pros
- Calcium chloride Container Dri II, described by Clariant as DMF-free
- Manufacturer-stated food-contact suitability for Container Dri II
- Separate Desi Pak ECO packets in a plastic-free, bio-based package
Clariant Cons
- Container Dri II and Desi Pak ECO are different families, so specifications must stay attached to the right product
Why We Picked Clariant
Clariant is third for buyers comparing cargo and package protection in one catalog. Container Dri II serves cargo applications; Desi Pak ECO provides small packets. We would check each product’s intended use rather than treat them as interchangeable.
Clariant reports that customers use Container Dri II Plus to protect approximately 500,000 metric tons of exported agricultural products each year. This is a vendor-reported figure, not an independent performance test.

4. Cordstrap
Cordstrap Pros
- Published four-step process: diagnose, advice, product and training
- Online Cargo Protection Guide plus an onsite scan to assess moisture risk
- Jointly agreed implementation plans, with experts in over 50 countries
Cordstrap Cons
- Installation guidance varies by model, so check the instructions for your chosen format
Why We Picked Cordstrap
Cordstrap’s published process suits buyers who want help planning installation. That planning matters whether a container is crossing an ocean or sitting on site, since storage remains one of the most common shipping container uses. Cordstrap says its moisture-control advice follows the CTU Code; this is the vendor’s stated framework, not independent certification of every shipment.
We found no verified review rating or completed numerical customer outcome for this comparison. Its placement here rests on the documented process and product choices.

5. TROPACK
TROPACK Pros
- TROPAsorb container bags with hooks and several sizes
- Specified Tyvek front and polyethylene-film back
- Manufacturer calculator for selecting quantities
TROPACK Cons
- Published quantity examples still need checking against the actual shipment
- No public price was shown on the reviewed pages
Why We Picked TROPACK
TROPACK makes its bag construction and hanging format clear. We included it for buyers comparing those practical details and seeking quantity guidance.
TROPACK says its TROPAsorb bags absorb around double their own weight in moisture and suit transport lasting 45 days or longer. These are manufacturer figures, not an independent test.
TROPACK Pricing
No public price was shown on the reviewed pages. Request a written, configuration-specific quote, including the recommended quantity, placement, shipping charges, availability and minimum order.
Conclusion
Super Dry is our top pick for a small importer seeking container units, in-box desiccants and optional SD+ consultancy. Its first-place position is an editorial recommendation for that use case, not proof that it outperforms the other suppliers.
Absortech is worth considering when placement choices drive the decision. Clariant offers separate cargo and small-packet ranges. Compare written recommendations and quote scope before ordering.
FAQ
What is the difference between container and in-box protection?
Container products address moisture around the load. In-box packs sit within individual packages. Ask which application your shipment needs.
How many bags should a shipment use?
There is no universal number. Ask for a recommendation based on cargo, packaging, route and trip length. Adding more bags does not necessarily improve protection.
Can moisture absorbers guarantee damage-free delivery?
No such guarantee is established here. Treat manufacturer absorption and leakage statements as claims, not independently verified promises.
What should a supplier quote include?
Request product details, quantity, shipping charges, availability, minimum order, placement instructions and selected support. Confirm what is included before comparing totals.
