"South American tung oil" refers to tung oil sourced from tung trees (Vernicia fordii or Vernicia montana) grown in South American countries such as Brazil. Tung oil is primarily produced in China and other East Asian countries, but there are also smaller-scale production operations in South America.

The properties and uses of South American tung oil are similar to those of tung oil sourced from other regions. It is a drying oil known for its ability to create a durable, waterproof finish on wood surfaces. South American tung oil can be used as a wood finish, providing protection against moisture, scratches, and other damage while enhancing the natural beauty of the wood.

Like other tung oils, South American tung oil may vary in quality depending on factors such as extraction methods, processing techniques, and purity. It is important to ensure that the tung oil purchased meets the desired specifications and quality standards for the intended application.
