Key Facts
Role Definition
MRO Purchasing Managers own the procurement strategy and execution for maintenance, repair, and operations materials.

Title Variants Across Operators
The MRO procurement leader carries different titles depending on the operator. ExxonMobil uses Category Manager for Indirect Materials. Marathon uses MRO Purchasing Manager. Valero and Phillips 66 use Procurement Manager for MRO. At petrochemical companies like Dow and LyondellBasell, the role may be titled Supply Chain Manager for Maintenance Materials or Indirect Procurement Lead.
Org Structure and Authority
MRO Purchasing Managers typically report to a Director of Procurement or VP of Supply Chain. They supervise two to five buyers or procurement specialists. Their purchasing authority ranges from $50,000 to $500,000 per transaction depending on the operator and spend category. Strategic sourcing decisions above these thresholds require director or VP approval.
How Vendors Should Engage
Vendors targeting MRO opportunities should engage the MRO Purchasing Manager after completing AVL prequalification. Bring data on pricing competitiveness, delivery reliability, and local inventory availability. MRO buyers value consolidated supply agreements that reduce transaction costs and improve delivery performance over lowest unit price alone.
