Coal-Based Cylindrical Activated Carbon, Iodine Value 900–1000 mg/g, CTC 60–80, CAS 64365-11-3
Coal-based cylindrical activated carbon candidate for overseas buyers requiring iodine value, CTC adsorption, particle size, hardness, ash, moisture, bulk density, and pH checks before RFQ. The source listing references regenerated/impregnated activated carbon wording and should be clarified for silver content, regeneration status, intended grade, and export documentation before purchase.

Package and route
Packing notes
Standard packing listed as 25 kg kraft paper bags
500 kg packing option referenced in source data; confirm bag type, liner, palletization, and container loading quantity
Customized product design and packaging are stated as available
Request export marks, batch number, net/gross weight, production date, and shelf-life labeling on each package
Listing states effective storage period of 24 months; confirm whether this is supplier warranty period and under what packaging condition
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
Industrial water treatment filtration media after buyer-specific validation
Gas-phase adsorption beds requiring CTC and hardness checks
Air purification media where dust, particle size, and adsorption performance are specified
Industrial decolorization where methylene blue value is relevant
Bulk activated carbon stocking for distributors needing export-ready documentation
Custom packed filtration media projects requiring 25 kg or jumbo bag supply
How we compare
Sourcing options
Request quotation by grade: 1A, 2A, or 3A with guaranteed iodine and CTC values
Request non-impregnated coal-based column activated carbon if silver is not required
Request silver-impregnated specification only if silver loading and leachability data are available
Request virgin-only material if regenerated carbon is not acceptable for the application
Request third-party pre-shipment testing for iodine value, CTC, ash, moisture, and particle size
Request palletized 25 kg bags for distributor resale or jumbo bags for industrial filter-bed filling
Human review
Compliance notes
Confirm whether the product is virgin, regenerated, reactivated, silver impregnated, or non-impregnated activated carbon; the listing title and specification table are not fully consistent
If silver impregnated, request silver loading percentage, impregnation chemistry, leachable silver data if relevant, and separate COA line items
Request current SDS, COA, TDS, packing list, commercial invoice, certificate of origin, and any third-party test report available for iodine value, CTC, ash, moisture, hardness, and particle size
Clarify intended use grade: industrial water treatment, air purification, gas-phase adsorption, decolorization, or other non-food/non-medical industrial use
Do not rely on platform claims as regulatory approval; buyer should conduct destination-market import and end-use checks
Activated carbon is commonly shipped as a chemical adsorbent; confirm HS code, UN/DG classification if applicable to the exact grade, and carrier acceptance before booking
For impregnated or regenerated grades, request confirmation of residual contaminants, heavy metals, volatile content, and odor profile relevant to buyer application
Confirm whether the material meets buyer-required standards such as ASTM, GB/T, AWWA, EN, or customer-specific methods, if applicable

Questions to confirm
Is the offered material virgin activated carbon, regenerated/reactivated activated carbon, silver impregnated activated carbon, or a standard coal column activated carbon?
What is the exact CAS number, HS code, and product name shown on the SDS and export documents?
Which grade is being quoted: 1A, 2A, or 3A, and what are the guaranteed minimum values for iodine value and CTC?
Can the supplier provide a recent batch COA showing iodine value, CTC, particle size distribution, hardness, moisture, ash/residue on ignition, bulk density, and pH?
If silver impregnated, what is the silver content range and test method, and is leachable silver data available?
What is the impurity profile, including ash composition, heavy metals, chloride/sulfate if relevant, odor, and dust/fines level?
Is the product suitable for the buyer’s target application: gas-phase adsorption, air purification, water treatment, industrial decolorization, or another specified use?
What packing is available for export: 25 kg bags, jumbo bags, palletized bags, or buyer-specified packaging?
