Granular Activated Carbon supplied by Zhengyi Filter Chemical Co., Ltd. is a porous adsorbent designed to capture contaminants from water, air, liquids and gases. The product’s high adsorptive capacity makes it suitable for a broad range of purification tasks and it can be regenerated repeatedly through thermal oxidation. Zhengyi is based in Central Hong Kong, occupying Rm 2302 on the 23rd floor of New World Tower 1, Queen’s Road, and is listed with a harbor trust tier.
In the activated‑carbon market the material is commonly characterised by a surface area between 800 and 1 200 m²/g and an iodine number of 800‑1 200 mg/g, both of which are typical for high‑performance GAC. Particle sizes are usually supplied in the 0.5‑2 mm range, giving a bulk density of 0.5‑0.7 g/cm³ and a moisture content below 5 %. These typical values provide a benchmark for evaluating the product’s performance and handling characteristics.
Typical buyers include municipal water treatment facilities, industrial air‑purification plants and companies that need to treat process liquids. The carbon can be incorporated into fixed‑bed filters, fluidised‑bed reactors or packed‑column systems. Specific trade details such as minimum order quantity, lead time and incoterms are not disclosed in the listing, so interested importers should contact Zhengyi directly to confirm these parameters.

Before finalising a purchase, verify the carbon’s reactivation capability, surface‑area measurement and any supplied test reports. Request a recent Certificate of Analysis and, if required, evidence of compliance with local environmental regulations. These documents help confirm that the material will meet your process specifications.
Logistics for Hong Kong‑based suppliers usually involve FOB or CIF terms, but the exact incoterm, lead time and freight options are not listed. Ask Zhengyi for a shipping quotation that includes port of loading, estimated transit time and any required export documentation. Payment terms such as T/T in advance or L/C at sight should also be clarified before contract signing.
Upon receipt, arrange a third‑party inspection to check particle size distribution, moisture content and bulk density against the agreed specifications. Conduct an adsorption test using a representative contaminant to validate performance. Retain the test certificates and the supplier’s shipping documents for customs clearance and future quality audits.
