That is because Brazil's P8 emission standard (similar to Euro VI) started in 2022 and Brazil had to reduce the sulfur in diesel to keep from killing the aftertreatments. When countries switch to ultra-law sulfur diesel the price goes up. ULSD = 15 ppm Sulfur or less
Brazil's emission standards are roughly 10 years behind Europe and the USA.
