Teak wood is indigenous to Thailand, Burma and parts of India and native to the soil there. It is not native to Indonesia and China which is where a majority of the mass produced teak furniture products in the U.S. market are from. Thai Teak is denser and has a higher natural oil content than teak from other countries.
“The location and climatic conditions where the tree grows makes a drastic difference in the proportion and formation of heartwood. Teak, scientifically known as Tectna grandis L.f., is a tropical hardwood species native to southeast Asia (India, Malaysia, Thailand and Burma). This species grows in moist tropical climate having rainfall of 1500-2000 mm with a marked 3-5 months dry season. Though teak can withstand high moisture than above, the quality of wood might be poor (color, texture and density) due to fast growth rate. “ - Finto Antony, Assistant Research Scientist at Warnell School of Forestry and Natural Resources, The University of Georgia
