Peru: On-Road Vehicles and Engines

Maximum permissible emission limits for existing vehicles, new imported or domestically assembled vehicles and used imported vehicles are as follows:

Starting 2003.01, all new light- and medium-duty vehicles in Peru were required to meet either US or EU emission standards (Euro 2 or US Tier 0). New heavy-duty vehicles were required to meet Euro II [6346].
Starting in 2007, new light- and medium-duty vehicles were required to meet Euro 3 or US Tier 1 requirements and new heavy-duty vehicles were required to meet Euro III requirements [6346].
Starting 2018.04, new light- and medium-duty vehicles were required to meet Euro 4 or US Tier 2 requirements and new heavy-duty vehicles were required to meet Euro IV requirements [6347].
Euro 6b/US Tier 3 for light- and medium-duty and Euro VI for heavy-duty were originally scheduled to take effect 2024.10 [6348]. However, a delay in implementing the required 10 ppm sulfur limit delayed the implementation of these standards to 2026.04 [6349].

Peruvian emission requirements for light-, medium- and heavy-duty vehicles are summarized in the following tables.

Fuels. A national limit of 10 ppm sulfur is scheduled to take effect 2025.10 for diesel (B5), gasoline and gasoline/alcohol blends. Diesel, regular gasoline and regular gasoline/alcohol blends are exempt in the regions of Loreto and Ucayali [6349].
