Markers
Markers in fuel are chemical additives intentionally added to fuels like gasoline, diesel, and jet fuel to identify and track their distribution and use.
These markers are typically unique and challenging to replicate, making it easier for authorities to detect illegal activities such as fuel adulteration, smuggling, and tax evasion.
Fuel markers can be added at various stages of the fuel supply chain, such as during refining, blending, or distribution. As a result, fuel markers are widespread, with many countries mandating their use in fuel products.
For example, the United States, Canada, and many European countries use dye-based markers in diesel fuel to differentiate between on-road and off-road diesel, which have different tax rates and usage restrictions. Other countries use markers to combat fuel fraud, a significant issue in developing nations.
Fuel markers can also be helpful for energy companies and government agencies to monitor fuel quality, track fuel consumption trends, and identify potential safety issues related to fuel use.
Fuel markers play a critical role in ensuring the integrity and traceability of fuel products, which is essential for maintaining reliable and efficient energy infrastructure.
