Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If 90%+ distills below 210°C and used as motor fuel
Light petroleum distillates meeting light oil definition classify under Chapter 27 petroleum oils.
If total unsaturation <50% butylene equivalent
Lower olefin content mixtures classify as other liquefied petroleum gases.
If lubricating oil base stock with butylene additives
Petroleum products containing lubricants classify under lubricating preparations.

Import Tips & Compliance
• 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
