Based in Guanzhu, at the centre of China's Qinan cluster.
Dianbai has traded agarwood for more than 1,500 years. We work at the centre of that supply chain.
Dianbai sits on the southern coast of Guangdong, where subtropical hills and monsoon rain suit Aquilaria sinensis. Today the district cultivates more than 26,000 acres and supplies most of China's grafted Qinan seedlings.
Oud Harvest is based in Guanzhu. We buy and grade at the workshop gate, so the batch you approve is the batch you receive.
Every gram processed under Oud Harvest originates exclusively from artificial plantation lots. We operate with zero wild logging tolerance and complete adherence to forestry origin verification, statutory felling permits, and yield calculation regulations.
