In international markets, PMI Comercio Internacional carries out crude oil purchase and sale operations for Pemex. 

Through the commercialization activity carried out, the country obtains income from the sale of crude oil, Mexico being one of the main exporters of crude oil worldwide.  PMI Comercio Internacional is the trading entity for crude oil in international markets and acquires from Pemex the balance between crude oil produced and domestic consumption for sale.  Worldwide, Pemex / PMI Comercio Internacional is recognized as a reliable supplier, establishing permanent and mutually beneficial relationships with our clients.

For this purpose, it has signed various contracts with foreign companies for the sale of crude oil in international markets.  With about 25 clients in America, Europe, the Far East and the rest of the world, PMI Comercio Internacional sells Maya, Istmo, Olmeca and Altamira crude.

 In 2014, PMI Comercio Internacional placed 1.14 million barrels a day (MMbd) in the international market according to Pemex's Petroleum Indicators, equivalent to 47% of total crude production. USA, Mexico ranks as the tenth largest producer worldwide. 


​PMI Comercio Internacional commercializes Maya, Istmo, Olmeca, and Altamira crude oils in the markets of Europe, the Americas and the Far East.

a)  Maya

It’s a heavy (21-22° API) and sour (3.4% of sulphur weight) crude oil, thereby producing lower yields for gasoline and diesel in simplified refining schemes when compared to lighter crudes. The loading ports of Maya are: Cayo Arcas, approximately 162 km off the coast of Ciudad del Carmen, in the State of Campeche; Dos Bocas, in the State of Tabasco; and Salina Cruz, in the State of Oaxaca.

To maximize the economic value of this type of crude oil, its processing requires refineries with high conversion units which transform the heavy elements (residues) of the crude oil into products with a higher value for the refiner. To this end, PMI Comercio Internacional has signed several long-term supply agreements with refiners that have high-conversion units, or that have agreed to expand the complexity of its refineries to obtain the highest value from Maya crude oil.


b)  Istmo

It is a medium (32-33° API) and sour (1.8% of sulphur weight) crude oil with good gasoline and intermediate distillates (diesel and jet fuel/kerosene) yields. The loading ports of Istmo crude oil are: Dos Bocas, in the State of Tabasco; Salina Cruz, in the State of Oaxaca, and Pajaritos, in Veracruz.
The highest economic value of this crude is obtained in refineries with FCC (Fluid Catalytic Cracker) units. Its quality is similar to the Arab light crude and the Russian Ural crude.


c)   Olmeca

It is the lightest of Mexican crude oils, with an API gravity of 38-39°, and a 0.73% to 0.75% Sulphur contents in weight, and therefore, it is a light and sweet crude. Its characteristics make it a good product for lubricants and petrochemicals. Olmeca crude cargoes are exported from Pajaritos, in the State of Veracruz.


d)  Altamira

It is a heavy crude, with a 15.5° to 16.5° API gravity, and a Sulphur contents of 5.5 to 6.0% in weight. As with Maya crude, this type of crude oil offers a lower gasoline and diesel performance in simple refining schemes compared to lighter crude oils. Its physical-chemical characteristics make it appropriate for asphalt production. Altamira crude cargoes are exported from the port of Tampico, in the State of Tamaulipas.
