Buyer FAQ
Activated carbon purchasing questions answered.
Answers for importers and project buyers about selection, specifications, samples, documents, packaging, testing, and shipment.
Common Questions
Practical answers before sending an inquiry.
Final recommendations still depend on application, target standard, test result, and shipment requirement.
How do I choose the right activated carbon?
Start with application, target contaminant, flow rate, contact time, target specification, and equipment type. Then match raw material, shape, particle size, and treatment method.
What is iodine value in activated carbon?
Iodine value is a common indicator for micropore adsorption capacity. It is useful for comparing grades, but final selection should also consider application, particle size, hardness, ash, and test result.
What is methylene blue value used for?
Methylene blue is often used to evaluate adsorption for larger molecules and decolorization applications, especially in powdered or wood activated carbon for liquid phase treatment.
Can you supply coconut shell, coal, and wood activated carbon?
Yes. AuroCarb can match coconut shell, coal, wood, pelletized, granular, powdered, acid-washed, impregnated, and catalytic activated carbon by application and target specification.
Can I request samples before bulk order?
Samples can be arranged after product type, application, target specification, quantity, and destination are confirmed. For technical projects, sample testing is recommended before bulk shipment.
Do you provide COA, TDS, and SDS documents?
Yes. COA, TDS, SDS or MSDS, packing list, commercial invoice, and other export documents can be prepared according to order and buyer requirements.
Can activated carbon packaging be customized?
Common packaging options include 20 kg or 25 kg bags, jumbo bags, pallets, neutral packaging, private labels, and moisture-protected packing when required.
Which activated carbon is used for gold recovery?
High-hardness granular or coconut shell activated carbon is commonly used for CIP, CIL, and CIC systems. Hardness, adsorption, abrasion resistance, and particle size control are important.
Which activated carbon is used for water treatment?
Granular, powdered, and coconut shell activated carbon are common choices for drinking water, wastewater polishing, aquaculture, filter media, and industrial reuse systems.
Which activated carbon is used for air or gas purification?
Pelletized, granular, impregnated, and catalytic activated carbon can be matched for VOC control, odor removal, H2S, ammonia, acid gas, and specialty vapor adsorption.
What information should I include in an inquiry?
Please include product type, application, target specification, quantity, destination country or port, Incoterms, packaging, label requirement, and sample needs.
Do you support third-party testing?
Third-party testing can be arranged according to order requirements, target market, and buyer specification. The testing scope should be confirmed before sampling or shipment.
