Calcium Chloride Dihydrate CAS 10035-04-8 for Dust Control and Road Maintenance Sourcing
Calcium chloride dihydrate sourcing candidate listed with CAS 10035-04-8, formula CaCl2·2H2O / CaCl2H4O2, EINECS 600-075-5, and solid form. Buyer review should focus on confirming assay or CaCl2 content, moisture/hydrate basis, insoluble matter, alkalinity/acidity, heavy metals where required, particle size or flake/granule form, and suitability for road maintenance or dust control procurement. The listing indicates China origin and customizable packaging, but the available page text does not provide a complete COA-style specification.

Package and route
Packing notes
Listing mentions 1 kg bag and 25 kg drum; confirm actual export packing options.
Supplier states tailored package can be provided on request; specify bag, drum, palletization, liner, and moisture-barrier requirements.
Because calcium chloride is hygroscopic, request packaging confirmation for moisture protection during sea freight and warehouse transit.
Confirm net weight, gross weight, pallet dimensions, container loading quantity, and whether export marks can match buyer requirements.
Request sample availability, sample size, sample freight terms, and whether sample COA matches commercial batches.
Applications and sourcing options
Check whether this product fits the buyer's actual application.
Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.
Use context
Common applications
Dust control on unpaved roads where local regulations and site requirements allow
Road maintenance chemical blending
Deicing or anti-icing formulations where calcium chloride dihydrate grade is suitable
Industrial hygroscopic salt applications requiring confirmed impurity limits
Bulk repacking or distribution after import compliance review
How we compare
Sourcing options
Request RFQ for 25 kg moisture-resistant bags, palletized for sea freight.
Request RFQ for drums if smaller lot handling or higher moisture protection is needed.
Ask for industrial/road-maintenance grade specification with COA before price comparison.
Request sample first for particle size, caking behavior, and moisture uptake checks.
Compare against 74–77% calcium chloride dihydrate or other stated concentration grades if application is based on active CaCl2 content.
Request Incoterms options such as EXW, FOB China port, CIF destination port, or DDP only where legally and operationally appropriate.
Human review
Compliance notes
Request current SDS in destination-market format before RFQ finalization.
Request COA for each batch showing assay, hydrate basis, insoluble matter, moisture, pH/alkalinity, and any buyer-specific impurity limits.
Confirm HS code, country of origin statement, commercial invoice/packing list format, and export documentation availability.
Confirm DG classification for the specific packing and transport mode; do not rely only on marketplace text.
Check destination requirements for road maintenance, dust suppression, environmental discharge, and public works procurement before import or use.
Listing references California Proposition 65 and SVHC reports as available supplier materials; request the actual documents and verify date, product match, and testing scope.
No regulatory approval, suitability guarantee, or exemption should be assumed from the listing alone.
