Middle Base Number Synthetic Calcium Sulfonate
Middle Base Number Synthetic Calcium Sulfonate is an overbased calcium sulfonate formulated with a middle total base number. The product contains 145 mg KOH g‑1 of TBN, 6.85 wt % calcium and 1.8‑2.2 wt % sulfur as verified by GB/T 265 and SH/T 0297 test methods. It is supplied in 200 litre metal drums and can be delivered as a liquid or paste for easy blending. The supplier states that the additive is intended for heavy‑duty engine oil and industrial grease formulations.
The sulfonate base provides superior high‑temperature detergency and acid‑neutralising capacity compared with lower‑BN variants. In the lubricant industry, middle‑BN sulfonates are typically used where a balance between detergency and ash content is required, and they meet the specifications of ISO 3448 for engine oil additives. The flash point of 180 °C (COC) ensures safe handling during high‑temperature processing. Recommended inclusion rates range from 0.5 % to 3.0 % of the finished oil blend.
Typical buyers include engine oil manufacturers, industrial lubricant formulators and rust‑prevention oil producers who need consistent performance in demanding environments. The product is packed in sealed metal drums, stored in a dry, well‑ventilated warehouse and shipped under the buyer’s chosen Incoterm. Because the listing does not disclose MOQ, lead time or payment terms, the importer should confirm those details directly with Jinzhou Runda Chemical Co., Ltd. before placing an order.

Sourcing Middle Base Number Synthetic Calcium Sulfonate from Jinzhou Runda Chemical Co., Ltd. - China Import Guide
Before placing an order, importers should verify the supplier’s quality certificates, request a recent analysis report confirming TBN, calcium and sulfur levels, and confirm that the product complies with any relevant local regulations. Asking for a sample batch and checking the batch number against the supplier’s documentation can further reduce risk.
Logistics for the 200 litre drums typically involve sea freight under the buyer’s chosen Incoterm, with lead times that vary by port congestion. Payment terms are not disclosed in the listing, so the importer should negotiate terms such as LC at sight or TT after inspection, and confirm any freight forwarder requirements.
During the sourcing process, arrange for a third‑party inspection to check drum integrity, verify the flash point and ensure the product matches the declared specifications. Request a full Material Safety Data Sheet and a Certificate of Analysis, and retain these documents for customs clearance and downstream quality control.
