Import Castor Oil — Buy in Bulk from Supplier in China

Castor oil from Jorge Martinez is a refined vegetable oil extracted from Ricinus communis seeds, with a density of 0.961 g/cm³ at 20°C and a viscosity range of 950 to 1,050 cSt at 40°C. The product is supplied in sealed drums, with typical moisture content below 0.1% and free fatty acid levels under 0.5%, consistent with industrial-grade standards. No additives or diluents are included in the base formulation.

This oil is typically classified as a non-drying triglyceride with a high ricinoleic acid content, usually between 85% and 90%, which gives it unique lubricity and chemical reactivity. It is commonly sourced from Chinese production zones in Sichuan and Yunnan, where climate conditions support high-yield ricinus cultivation. The refining process removes impurities and residual proteins, resulting in a pale yellow, nearly odorless liquid suitable for technical applications.

Buyers include manufacturers of lubricants, cosmetics, pharmaceuticals, and bio-based plastics. The oil is shipped in 180kg steel drums or 200kg HDPE containers, with standard packaging for ocean freight. Minimum order quantities are confirmed directly with the supplier, and delivery terms are negotiable under FOB Qingdao or CIF terms depending on destination.
