Industrial filler for plastics and rubber compounds
Opacity and filler component in paints and coatings
Paper brightness and filler applications
Construction materials, sealants, tiles, and cement-related formulations
General industrial mineral filler sourcing where particle size, whiteness, and moisture are key purchasing checks
Nano calcium carbonate evaluation where surface treatment and particle size confirmation are required
How we compare
Sourcing options
Request quote for industrial-grade calcium carbonate powder, 25 kg PP bags, full-container shipment
Request quote for nano calcium carbonate grade with specified 20–40 nm or 40–60 nm particle size range
Request coated or surface-treated CaCO3 grade for polymer or rubber applications
Request pre-shipment sample with COA and matching commercial-lot specification

Request third-party inspection before shipment for assay, particle size, whiteness, and packing condition
Human review
Compliance notes
Verify CAS 471-34-1, formula, grade, and intended application against the buyer’s destination-country requirements before ordering
Request latest COA for the exact batch or representative lot, including CaCO3 assay, particle size distribution, whiteness, moisture, pH, insoluble matter, heavy metals if relevant, and any surface treatment information
Request SDS in GHS format and confirm non-dangerous goods status or any applicable transport classification with the supplier and freight forwarder
If intended for food additive, feed, pharmaceutical, cosmetic, or supplement use, do not rely on the industrial-grade listing; request specific regulatory-grade documentation and destination-market suitability evidence
Confirm whether the product is natural ground calcium carbonate, precipitated calcium carbonate, nano calcium carbonate, coated calcium carbonate, or surface-treated grade
Confirm correct HS code, export documents, country of origin, packing list, commercial invoice, COA, SDS, and any inspection documents required by the destination market
No regulatory approval, customs clearance, or end-use suitability is implied by this sourcing profile

Questions to confirm
Can you confirm the exact product type: GCC, PCC, nano calcium carbonate, coated calcium carbonate, or standard industrial filler grade?
Please provide the current TDS and COA for CAS 471-34-1 matching the offered grade.
Which purity specification applies to the quoted product: ≥99%, ≥98%, or ≥95% for nano grades?
What is the particle size distribution, D50/D97, and test method for the offered grade?
Is the powder surface-treated? If yes, what treatment agent is used and at what approximate loading?
What are the limits for moisture, whiteness, oil absorption, pH, acid-insoluble matter, heavy metals, and residue on sieve?
Is the product suitable only for industrial applications, or can you provide separate documentation for food, cosmetic, feed, or pharma applications if requested?
Can you provide SDS, COA, TDS, ISO certificate, export license information, and sample documentation before PI?
