MRO products in industrial procurement: definition, categories and sourcing strategies
When a production line comes to a standstill because a ball bearing is missing, that is not a direct procurement problem. It is an MRO problem. Maintenance, Repair and Operations refers to a procurement area that is organizationally underestimated in many companies, even though it has a direct impact on production capability. This article explains what MRO means, which products fall under it, why procurement is so complex, and how companies can become more efficient.
What does MRO mean?
MRO stands for Maintenance, Repair and Operations. The term refers to all materials, spare parts and services that are necessary to keep plants, machines and infrastructure operational. MRO goods are not raw materials and do not directly become part of the end product. Formally, they are classified as indirect procurement. Nevertheless, they are business-critical, because without functioning maintenance there can be no production.
Which product categories fall under MRO?
MRO can be divided into three core areas. Maintenance includes all preventive maintenance measures: lubricants, filters, seals, wear parts as well as measuring and inspection equipment. Repair refers to reactive measures in the event of failure or malfunction. This includes spare parts, rolling bearings, drives, pneumatic components, electronic controls and tools. Operations includes all consumables and operating supplies for day-to-day operations, including personal protective equipment, cleaning agents and operating supplies.
Typical MRO brands in the industrial environment are Siemens, Festo, SEW Eurodrive, SKF, INA, Schneider Electric, SMC, Phoenix Contact, KUKA and Keyence. The variety of brands is a key factor in the complexity of MRO procurement.
Why is MRO business-critical despite being part of indirect procurement?
The formal classification as indirect procurement tempts companies to treat MRO as a lower priority. That is a mistake. A missing spare part can bring an entire production line to a halt. The cost of unplanned machine downtime exceeds the value of the missing component many times over. In the MRO area, security of supply therefore takes precedence over pure price optimization. MRO is not a peripheral issue, but a strategic lever for production stability and delivery capability.
What challenges are typical for MRO procurement?
In practice, MRO procurement is more demanding than other procurement areas for several reasons. The supplier base is highly fragmented: rolling bearings, pneumatics, control technology and tools often come from different manufacturers and distributors. In addition, there is a high number of individual order items with a low goods value per transaction. Many MRO requirements cannot be planned, arise ad hoc when machines fail, and require an immediate response. Particularly challenging is the procurement of discontinued components for older plants for which no successor products are available on the market. At the same time, there is a structural tension between inventory carrying costs and the risk of a lack of supply when demand arises.
How high are the typical MRO procurement costs?
Depending on the industry, 10 to 25 percent of total procurement volume is attributable to MRO requirements. However, the share of ordering transactions is disproportionately high. Many MRO orders have a goods value of less than 300 euros. These are offset by above-average process costs per ordering transaction. In the case of one-off requirements involving new suppliers, manual master data creation and urgent procurement, the actual process costs are significantly higher. According to studies, master data maintenance alone costs between 100 and 500 euros per supplier per year. Depending on the company, rolling bearings can account for up to one third of total supply chain costs.
What are the biggest cost drivers in MRO?
The main cost drivers in MRO procurement are:
• Fragmented supplier base with high coordination effort and high master data costs
• Manual special procurement outside catalogs and framework agreements
• Expedite surcharges for urgent procurement without lead time
• Safety stock as a buffer against supply failures
• Maverick buying by maintenance teams that order directly and without control
How can MRO procurement be designed efficiently?
Efficient MRO procurement begins with consolidating the supplier base. Those who bundle all requirements through a central procurement service provider reduce master data costs, avoid maverick buying and gain full spending transparency. The single-creditor model of CS Beschaffung addresses exactly this issue: all MRO requirements are handled through a single supplier. You report the requirement, CS Beschaffung takes over brand-independent procurement from national and international suppliers, coordinates delivery and issues a consolidated invoice.
Another advantage of the external procurement model is the availability of discontinued items. For older plants that are no longer regularly supplied, research in the international market is often the only way to ensure security of supply.
When is outsourcing MRO procurement worthwhile?
Outsourcing is particularly economical when many suppliers with low individual order values are managed, when short-term requirements arise without framework agreements, when internal procurement resources are scarce, or when discontinued components must be procured regularly. Companies without their own purchasing department benefit most, because the administrative effort is eliminated entirely.
Conclusion
MRO products are not an operational side issue, but a business-critical procurement area with high optimization potential. The combination of high supplier diversity, low order values and unpredictable requirements makes MRO one of the most cost-intensive areas in indirect procurement. Those who approach MRO strategically and consolidate operational processing reduce process costs, improve security of supply and relieve internal teams.
