Import Tips
• Submit Saybolt viscosity and API gravity test results from accredited labs to validate No. 4 specifications
• Label containers clearly with sulfur content and biodiesel ratio to facilitate CBP examination
• Check state-level sulfur regulations that may require additional filtration post-import
