Petrojam is a limited liability company owned by the government of Jamaica. It is Jamaica's only petroleum refinery. Petrojam supplies a full range of domestic, transportation and industrial petroleum products. We also operate a laboratory that provides quality control and certification services for petroleum products manufactured and imported by the refinery. Laboratory service is also provided to Jamaican businesses and the scientific community. Our laboratory's primary function is to ensure that the products we supply to the market, whether produced or imported, meet all legal and contractual specifications. Samples are tested and analysed from all process unit streams and blended products to ensure that they meet the specifications required by the refinery. Each batch of fuel, including gasoline, kerosene, automobile diesel, heavy fuel oil, LPG, ethanol and asphalt, is analysed.
