Excerpts from the report Preface: Under authority of the Agricultural Marketing Act of 1946 (RMA, Title II), a marketing research project was organized to analyze the methods and practices of oilseed mills in relation to costs and margins, and their effects on return to growers. A study of tung milling is one part of that project. Tung oil is classified by the Munitions Board as one of the six strategic oils. Production from domestic tung groves is roughly equivalent to a fifth of normal domestic requirements. This study is an attempt to analyze the methods, practices, and economic efficiency of the processing mills through which the domestic tung crop passes to the industrial users of tung oil. At the time mill data were obtained the industry was composed of 14 mills. The smallness of this number put stringent limitations on the analysis.
