Entity

Pemex Transformación Industrial, S.A. de C.V. (PTI) is the downstream operating subsidiary of Petróleos Mexicanos (PEMEX), responsible for the entirety of Mexico's state-owned refining, gas processing, petrochemical production, and fertilizer manufacturing. It is one of PEMEX's two Empresas Productivas del Estado Subsidiarias (EPES) — wholly state-owned productive entities operating with a degree of commercial autonomy under Mexican law.

Formation & History

PTI was created on 1 November 2015 under Mexico's 2013 energy reform (Ley de Petróleos Mexicanos, published Aug 11, 2014; in force Oct 7, 2014), which dissolved the old subsidiary structure and consolidated downstream operations into a single entity. The Board of Directors approved the creation agreement on March 27, 2015; it was published in the DOF on April 28, 2015; and the Declaratoria de entrada en vigor was published October 6, 2015, making PTI effective November 1, 2015. It absorbed the assets and personnel of three predecessor companies:

• Pemex Refinación — operated the national refinery network
• Pemex Gas y Petroquímica Básica (PGPB) — operated gas processing complexes and basic petrochemicals
• Pemex Petroquímica (PPQ) — operated secondary petrochemical complexes

This consolidation eliminated the legal separation between refining, gas processing, and petrochemicals that had existed since 1992.

Scope of Activities

PTI's mandate covers the full downstream transformation chain:

• Crude oil refining — production of gasoline, diesel, aviation (turbine) or industrial (fuel oil) fuels, LP gas, asphalt
• Natural gas processing — NGL extraction, fractionation, sulfur recovery
• Basic petrochemicals — ethylene, propylene, BTX aromatics, ammonia, methanol
• Secondary petrochemicals — polyethylene, ethylene oxide, glycols, acrylonitrile, solvents
• Fertilizers — ammonia, urea, ammonium nitrate (via CPQ Cosoleacaque, Morelos, Escolín)
• LPG logistics — storage and distribution
• Crude oil storage terminals — including Dos Bocas and Salina Cruz
• Pipeline transport — including the Amonia-Ducto Transístmico (ammonia pipeline)
• International trade — imports and exports of hydrocarbons and petrochemicals

In 2024–2025, PTI traded approximately $17.19B in imports and $7.20B in exports.

The official Estatuto Orgánico de PTI (last amended September 2022, Session 57, Accord CAEPS-PTRI-027/2022) lists the following formally constituted management units:

Current Strategic Priority — $5.3B Investment Plan (2026–2030)

PTI is the executing entity for the Mx$93 billion (~$5.3B USD) petrochemical and fertilizer revival program announced June 5, 2026, targeting:

• Aromatics: 329,000 t/yr via Cangrejera + Pajaritos (Mx$11B)
• Ammonia: 957,000 t/yr via Morelos + Cosoleacaque (Mx$13B)
• New fertilizer plant at Escolín: 700,000+ t/yr ammonia + urea (Mx$25.3B)
