Thailand is the worlds third largest producer of crude palm oil, producing approximately two million tonnes per year, or 1.2 percent of global output. Ninety-five percent of Thai production is consumed locally. Almost 85 percent of palm plantations and extraction mills are in south Thailand. At year-end 2016, 4.7 to 5.8 million Rai (unit) were planted in oil palms, employing 300,000 farmers, mostly on small landholdings of 20 rai. ASEAN as a region accounts for 52.5 million tonnes of palm oil production, about 85 percent of the world total and more than 90 percent of global exports. Indonesia accounts for 52.2 percent of world exports. Malaysian exports total 37.9 percent. The biggest consumers of palm oil are India, the European Union, and China, with the three consuming nearly 50 percent of world exports. Thailands Department of Internal Trade (DIT) usually sets the price of crude palm oil and refined palm oil. Thai farmers have a relatively low yield compared to those in Malaysia and Indonesia. Thai palm oil crops yield 4-17 percent oil compared to around 20 percent in competing countries. In addition, Indonesian and Malaysian oil palm plantations are 10 times the size of Thai plantations.
