Import Tips
• Provide refinery process flow diagrams and composition analysis showing butylene predominance post-BD extraction
• Declare Reid Vapor Pressure (RVP) values as they impact fuel blending regulations and classification
• Avoid bulk import without terminal allocation; pre-arrange cryogenic storage with certified facilities
