We are interested in buying UCO because we are planning to start a soap business soon. Our initial monthly needs are expected to be around 20-22 Tons. Hopefully, we can arrange larger regular shipments in the future. Can it be shipped in a flexitank?. Is it always a mix of different types of oils? Are there oil specifications that you go by? like M.iu, saponification value, water content, etc.?
