Tianjin Guofu Import And Export Co., Ltd. offers carbon black grade N550 for industrial applications. While the listing does not disclose measured iodine absorption, industry data shows N550 typically achieves 80‑95 g/kg under GB3778‑2011. The grade is characterised by a smooth surface and high structure, attributes that improve strength and durability in rubber and plastic compounds. Standard test methods such as the Iodine Absorption and Oil Absorption tests are used to verify these properties.
Typical oil absorption for N550 lies between 95‑110 × 10⁻⁵ m³/kg, and the particle surface area generally ranges from 70‑80 m²/g. The high‑structure nature provides a larger network of filler particles, which enhances tensile strength and wear resistance in tyre compounds. Common bulk density values are 350‑380 kg/m³, and moisture content is usually kept below 0.5 % to maintain performance. These specifications align with the requirements of automotive tyre manufacturers and other rubber product makers.
The product is supplied in bulk, often in 20‑25 kg bags or larger jumbo bags, and buyers should confirm the exact packaging size with the supplier. Because MOQ and lead‑time are not listed, importers are advised to request these details directly from Tianjin Guofu. Negotiation of Incoterms such as FOB or CIF and payment methods like L/C or T/T is handled between the buyer and the supplier.

Importers should first request Tianjin Guofu’s latest material safety data sheet, test certificates and any third‑party inspection reports to confirm the grade matches their specifications. Verifying typical iodine and oil absorption values helps avoid performance issues in downstream processing.
Logistics for bulk carbon black are arranged from Tianjin’s nearby ports or inland freight hubs. Buyers need to clarify expected lead‑time, which can vary with production scheduling, and agree on Incoterms such as FOB or CIF together with payment terms like L/C or T/T. These details are not listed and must be confirmed directly with the supplier.
Quality control generally includes sampling on arrival, checking moisture, ash and particle size against the supplied data, and optionally conducting independent laboratory analysis. Engaging an inspection agency to verify compliance with GB3778‑2011 can reduce risk. Review the certificate of analysis, packing list and bill of lading before accepting the shipment.
