| Part Compatibility and Fit | Incorrect dimensions or interfaces can cause equipment downtime, installation delays, and safety risks. | 100% match against machine model, serial range, drawing revision, and technical specification before shipment. | Dimensional drawings, cross-reference list, compatibility statement, and sample inspection report. | 20% |
| Material and Metallurgical Quality | Wear parts such as crusher liners, bucket teeth, and mill components require controlled hardness, toughness, and composition. | Material certificates and heat or batch traceability for every critical wear or load-bearing part. | Chemical composition report, hardness results, heat-treatment records, and batch identification. | 15% |
| Quality Management System | A controlled quality system reduces variation, nonconformities, and repeat failures across production batches. | A current ISO 9001 certificate covering the relevant design, manufacturing, inspection, or distribution activities. | Certificate number, certification scope, issuing body, expiry date, and recent audit or corrective-action records. | 12% |
| Inspection and Testing Capability | Independent inspection helps detect dimensional, surface, hardness, pressure, and assembly defects before delivery. | Documented inspection plans for critical parts, with calibrated equipment and recorded acceptance criteria. | Inspection and test plans, calibration certificates, non-destructive testing records, and final inspection reports. | 10% |
| Lead Time and Availability | Delays in high-wear or critical components can extend unplanned maintenance and reduce production output. | Written lead-time commitments by part category; stocked standard items should normally ship faster than engineered-to-order parts. | Inventory policy, production schedule, historical delivery records, and escalation procedure for urgent orders. | 10% |
| On-Time and In-Full Delivery | Reliable delivery planning supports shutdown maintenance, spare-parts forecasting, and working-capital control. | Target an OTIF performance of at least 95%, measured over a defined period and order population. | At least 6–12 months of delivery-performance data, including late, short, and damaged shipments. | 8% |
| Warranty and Nonconformance Handling | Clear remedies reduce the financial and operational impact of premature failure or incorrect supply. | Written warranty terms, defined claim-response times, root-cause analysis, and replacement or credit procedures. | Warranty period, exclusions, claim form, corrective-action template, and anonymized claim-resolution records. | 8% |
| Technical Support and Documentation | Accurate installation, maintenance, and application guidance helps prevent fitment errors and premature wear. | Technical responses within one business day for routine requests and documented support for critical applications. | Installation instructions, maintenance recommendations, parts lists, service contacts, and response-time records. | 6% |
| Supply-Chain Traceability | Traceability supports recalls, root-cause investigations, inventory control, and regulatory or customer audits. | Unique part, batch, or heat identification retained from production through shipment and after-sales service. | Traceability procedure, labels, packing records, supplier-control process, and retention-period policy. | 4% |
| Health, Safety, and Environmental Controls | Responsible manufacturing and handling practices reduce workplace, environmental, and compliance risks. | Risk-based controls supported by applicable occupational-safety and environmental management procedures. | Relevant management-system certificates, safety records, environmental permits, and material-handling procedures. | 3% |
| Total Evaluation Weight | Use a weighted scorecard and verify critical technical requirements before comparing commercial terms. | 100% |
