Import Carbon Black — Buy in Bulk from Supplier in South Africa

Ouansi Investment, an imported-tier chemical trader based in South Africa, lists carbon black among its product portfolio. The company states it can supply carbon black in both retail packs and bulk containers. Their catalogue also includes water-treatment chemicals, inorganic chemicals and specialty additives. No further quantitative details are provided in the listing.

Carbon black is commonly produced as furnace or thermal grades with particle sizes between 20-100 nm, iodine numbers from 80 to 150 and surface areas of 50-150 m2 g-1; these values are typical for the industry and apply unless a specific grade is requested. Purity is generally 99% or higher, and bulk density usually ranges from 0.5 to 0.9 g cm-3. Such characteristics influence dispersion and reinforcement in rubber or pigment performance in plastics. Ouansi Investment does not specify a particular grade, so buyers should request the exact specification sheet.

Typical end-users include rubber manufacturers, plastic processors, inks and coatings producers who require consistent colour and reinforcement. Buyers should confirm packaging size, minimum order quantity and preferred Incoterms before placing an order. Trade terms such as payment method and lead time are not disclosed in the listing and need to be negotiated directly with the supplier.

Ouansi Investment operates from South Africa and is classified as an imported-tier supplier with a harbor trust rating. The platform records a response rate of 0.00 and no average response time, indicating that communication may require proactive follow‑up.

The supplier’s description highlights a broad portfolio that includes water‑treatment chemicals, inorganic chemicals, food‑grade additives, rubber and plastic chemicals, as well as specialty items such as carbon black. While the listing confirms the ability to supply both retail and bulk quantities, no further operational details such as production capacity or client references are provided.
