Diesel Net's emissions page (great source on global emission standards) says.

PROCONVE P-6 standards, based on Euro IV, were scheduled to become effective from 2009. However, because low sulfur diesel fuel was not available, the P-5 stage remained in effect until the end of 2011.

That could be based on the 2008 financial crisis. Brazil wouldn't have wanted to pay to upgrade their refineries to make ultra-low sulfur diesel nor pay to import it from other countries.

Mexico's adoption of Euro V was also delayed due to lack of ULSD.

That was the official claim from the government at that time.

The so-called Premium refineries meant to be built in Ceará and Maranhão were never finished, basically due to widespread corruption at Petrobras under some former governments.
