Tung oil is pressed from the seeds of the tung tree. Tung trees can be found all over the world, but the largest groves that produce enough oil to be sold are mainly located in China and South America. Fun fact, tung tree’s used to be grown here in the United States, Florida to be specific, but were unfortunately wiped out due to hurricanes, blights, and other natural factors. We source our pure tung oil from China (Chinawood Oil) due to the higher quality and better color of tung oil that the Chinese tung tree groves provide.
