| Fit and compatibility | Confirm the tooth matches the ripper shank and machine application. Check the part reference, dimensions, pin or lock arrangement, and fitment details before ordering. | Dimensioned drawing, fitment list, and a trial installation or sample check. | 20% |
| Material and heat treatment | Ask what material and heat-treatment process are used, and how the supplier balances wear resistance with resistance to impact-related damage for the intended work. | Material specification, heat-treatment controls, and test results linked to the product or production lot. | 20% |
| Manufacturing quality control | Check how incoming material, critical dimensions, finished parts, and nonconforming products are controlled. Ask how production batches can be identified. | Inspection records, sample reports, batch traceability information, and a written quality-control process. | 15% |
| Wear-life performance | Compare expected wear using the same machine, material, operating method, and site conditions. Wear life can vary substantially with ground conditions and operator practices. | Documented field-trial results or a controlled comparison using the same operating conditions; treat unqualified life claims cautiously. | 15% |
| Production capacity and delivery | Confirm the order quantity, production schedule, stock availability, shipping method, and quoted dispatch date. Distinguish production time from transit time. | Written lead-time commitment, order status updates, and a shipment plan showing the delivery terms. | 10% |
| Price and total cost | Compare the complete delivered cost, not only the unit price. Include tooling or setup charges, packaging, freight, duties, payment terms, and expected replacement frequency. | Itemized quotation with currency, quantity breaks, delivery terms, and any additional charges clearly stated. | 10% |
| Warranty and after-sales support | Review the warranty period, coverage, exclusions, claim evidence requirements, and process for addressing fitment or quality issues. | Written warranty terms and a named contact or documented procedure for technical and quality claims. | 5% |
| Communication and documentation | Assess whether the supplier answers technical questions clearly and provides consistent drawings, specifications, packing details, and export documents. | A complete quotation and product file, prompt responses, and sample commercial or shipping documents where appropriate. | 5% |
