Bulk Calcium Chloride Ice Melt — CaCl₂ Deicer that Works to −25°F, Export from Turkey & UAE
SUHA International supplies bulk calcium chloride ice melt — the exothermic CaCl₂ deicer that pulls moisture from the air, releases its own heat, and keeps melting long after rock salt stops working. Available as pellets, flakes, granules and liquid brine, with COA per batch and a formal FOB / CIF / DDP quote within 24 hours, shipped from Jebel Ali and Mersin to 40+ countries.
What Is Calcium Chloride Ice Melt (CaCl₂)?
Calcium chloride (CaCl₂) is the inorganic salt that sets the professional standard for snow and ice management. Unlike ordinary rock salt, it is strongly hygroscopic — it draws moisture from the air and ice surface to start melting on contact — and exothermic, generating its own heat as it dissolves. CAS number 10043-52-4, molecular weight 110.98 g/mol. That combination is why it keeps working in deep cold where sodium chloride sits inert.
As a dedicated calcium chloride supplier operating from Turkey and the UAE, SUHA International matches the right form and grade to your operation — pellets for large lots, flakes for fast surface melting, granules for residential use, and 30–35% liquid brine for pre-storm anti-icing — and ships under full documentation control. For the chemistry baseline, see the calcium chloride profile on Wikipedia and the PubChem compound record.
📊 Market Insight (2026): Demand for high-performance deicers keeps rising as facility managers move away from high-volume rock salt toward lower-dose chloride products that cut labor, storage and refreezing. For critical access points — hospital ramps, fire-station exits, loading docks — calcium chloride remains the benchmark for speed and low-temperature reliability.

How Calcium Chloride Melts Ice So Fast
The speed advantage comes from a three-stage sequence — each stage feeds the next, which is why calcium chloride begins working in conditions where rock salt cannot get going.
It attracts moisture (hygroscopic)
Calcium chloride draws liquid from its surroundings and starts dissolving even in dry, low-humidity cold where rock salt sits inertly on the surface.
It releases heat (exothermic)
As the molecules dissociate they give off roughly 745 kJ/kg (about 320 BTU/lb). That heat hits the ice–pavement interface and breaks the adhesive bond that makes ice hard to remove mechanically.
It depresses the freezing point
The resulting brine resists refreezing. At its eutectic concentration (~30% by weight) it stays liquid to about −60°F (−51°C), keeping surfaces clear far longer between applications.
Practical Melting Limit vs. Other Deicers
Calcium Chloride vs Rock Salt vs Magnesium Chloride
Performance figures below are consistent with published deicer references and field guidance from chloride suppliers. The short version: calcium chloride costs more per ton, but lower application rates and fewer reapplications often make it the more economical choice across a full winter — especially below rock salt's working range.
| Property | Calcium Chloride (CaCl₂) | Rock Salt (NaCl) | Magnesium Chloride (MgCl₂) |
|---|---|---|---|
| Practical melt limit | −25°F (−32°C) | ~15–20°F | ~0 to −13°F |
| Melting action | Immediate, exothermic | Slower, absorbs heat | Moderate |
| Heat on dissolving | ~320 BTU/lb released | None (endothermic) | Low |
| Material cost / ton | Higher | Lowest | Moderate |
| Application quantity | 30–50% less | High volume | Moderate |
| Risk to cured concrete | Moderate (low at light dose) | Higher (scaling) | Moderate |
| Paw / surface irritation | Moderate | Moderate–high salinity | Moderate |
Five Benefits That Matter on the Ground
Extreme-cold performance
Rock salt loses melting power below ~20°F; calcium chloride keeps working to −25°F — indispensable for northern states, Canada and high-altitude sites.
Rapid exothermic action
The heat it generates lets it penetrate ice noticeably faster than sodium chloride near 20°F — the speed that is non-negotiable on hospital ramps and fire-station exits.
Lower application rates
At the recommended 1–3 oz per square yard it does the work of roughly double the rock salt, cutting labor, refills and storage.
Gentler on cured concrete
Applied sparingly to concrete at least a year old, the lower total chloride exposure means less freeze-thaw stress than heavy, repeated rock-salt doses.
Long residual effect
The brine clings to the surface instead of washing straight off, holding back black-ice formation and reducing how often crews reapply during long storms.
Versatile beyond winter
The same CaCl₂ also handles dust control on gravel roads, cold-weather concrete acceleration and industrial desiccation — one product, multiple programs.
How to Apply It Safely & Efficiently
Correct application maximizes performance and minimizes waste and surface damage. The rule of thumb: clear loose snow first, spread the minimum effective dose, then remove the slush.
Step by step
Clear loose snow first
Shovel or plow heavy accumulation — calcium chloride is built to break bonded ice, not feet of fluffy snow.
Use a calibrated spreader
A drop or rotary spreader gives even coverage; avoid clumped piles that waste product and leave gaps.
Target high-traffic zones
Entrances, north-facing slopes, accessibility ramps and loading docks come first.
Apply the minimum effective dose
Roughly ¼ to ½ cup per square yard. More is not better — it leaves sticky residue and stresses the surface.
Timing matrix
| Phase | What to do | Why it works |
|---|---|---|
| Anti-icing (pre-storm) | Light, uniform layer 1–2 hrs before snowfall | Stops snow bonding to asphalt — easier plowing |
| During the storm | Reapply lightly every 3–4 hours | Prevents traffic compacting snow into ice |
| Post-storm | Break up patches, then scrape slush away | Removes chloride from the surface |
Pets, Plants, Surfaces & the Environment
Pets
Calcium chloride is an irritant and can burn paw pads. Wipe paws with a damp cloth after walks and keep pets off freshly treated surfaces until the brine is rinsed or swept.
Plants & lawns
Chloride runoff can damage roots. Sweep up excess granules after melting and direct drainage away from beds and turf.
Surfaces
Never apply to concrete under 12 months old. On aging concrete, pre-wet the surface or use a magnesium-chloride blend where spalling is a concern.
Waterways
Use less, recover residue, and rely on shoveling and plowing as the primary removal method to limit chloride entering stormwater.

FAQ — Calcium Chloride Ice Melt
How is calcium chloride ice melt different from rock salt?
It keeps melting ice to about −25°F and releases heat as it dissolves, while rock salt loses practical melting power around 15–20°F and absorbs heat. It also needs 30–50% less material for the same result, which is why it is the default for commercial sites and extreme-cold climates.
What is the lowest temperature it works at?
It melts ice down to about −25°F (−32°C) in practice. At its eutectic concentration (~30% by weight) the brine stays liquid to roughly −60°F (−51°C), though melting speed drops sharply as you approach that limit.
Will it damage my concrete driveway?
On fully cured concrete at least 12 months old, it is generally safer than rock salt because you use less of it. Never apply it to new, unsealed or already-spalled concrete, and sweep up residue once the ice has melted.
Is it safe for pets to walk on?
No deicing salt is fully pet-safe. Calcium chloride can cause irritation and chemical burns to paws. Wipe paws immediately after outdoor exposure and use designated pet-safe walkways where possible.
What forms and packaging does it ship in?
It ships as pellets, flakes, granules and 30–35% liquid brine. Packaging includes 25 kg bags, 1000 kg FIBC jumbo bags and bulk loads. Standard minimum order is one 20-ft container (FCL), with trial quantities available for new buyers.
What is the CAS number and HS Code for calcium chloride?
The CAS number is 10043-52-4, molecular formula CaCl₂, molecular weight 110.98 g/mol. The HS Code is 2827.20. We handle all export customs documentation from Turkey and UAE using the correct classification.
