- Petroleum oils and oils obtained from bituminous minerals (other than crude) and preparations not elsewhere specified or included, containing by weight 70% or more of petroleum oils or of oils obtained from bituminous minerals, these oils being the basic constituents of the preparations, other than waste oils: (HS 27101) . Liquid fuels (ICS 75.160.20)

Automotive gasolines are essentially blends of hydrocarbons derived from petroleum and may contain selected additives that impart specific features to the finished gasoline. The hydrocarbons are derived from fractional distillation of crude oil, and associated processes that increase either the amount or the quality of the gasoline obtained. The resulting components vary from individual hydrocarbons such as, normal butane, to products that contain hundreds of different hydrocarbons. The properties of commercial gasolines are influenced by the refinery practices employed and the nature of the crude oils from which they are produced. Finished gasolines encompass a boiling range of about 30°C to 225°C. This standard specifies requirements and test methods for two grades of unleaded gasoline: Premium and Regular for use in spark-ignition internal combustion engines in Belize.
