Nestled in Hongjiang City, Hunan Province—China’s celebrated “Capital of Tung Oil” and the nation’s leading producing region—our company draws on a legacy where tung oil was once valued as a strategic resource dating back to the early 20th century.

Yuanjun Oil Industry began as a humble family workshop in the 1980s. Today, after two generations of dedication, we’ve grown into a modern facility spanning more than 3,000 square meters, producing over 300 tons of oil annually. We specialize in pure, high-quality tung oil and camellia oil.

We use only wild-harvested local seeds—never diluted, never altered. With decades of expertise and advanced production technology, our tung oil meets the most demanding international standards. It’s trusted by clients across the United States, Japan, Southeast Asia, and Europe.

We invite you to test our samples or visit our facility— see for yourself why so many choose Yuanjun.
