| Product Safety and Rated Capacity | 18% | Working Load Limit (WLL), safety factor, product type, size range, temperature limits, and lifting configuration. | Product labels, technical drawings, user instructions, load charts, and test reports showing WLL and applicable lifting angles. | 5 = complete and consistent data for all major products; 1 = unclear or unsupported ratings. |
| Testing and Certification | 15% | Proof-load testing, breaking-load testing, dimensional inspection, fatigue testing where applicable, and certificate availability. | Batch-specific test reports; calibrated equipment records; laboratory competence supported by ISO/IEC 17025 accreditation where applicable. | 5 = independent or accredited testing with batch traceability; 1 = only general promotional claims. |
| Material and Batch Traceability | 12% | Raw-material grade, heat or batch number, supplier records, production date, inspection status, and certificate linkage. | Material certificates, barcode or serial-number system, incoming inspection records, and retained production documentation. | 5 = product-to-material traceability is demonstrable; 1 = no verifiable traceability system. |
| Standards Coverage | 10% | Applicable standards for web slings, roundslings, wire-rope slings, chain slings, shackles, hooks, and other lifting accessories. | Evidence of design and testing against relevant requirements such as ASME B30.9, ASME B30.26, EN 1492, EN 818, EN 13414, or ISO 2408, as applicable to the product. | 5 = standards are clearly identified by product; 1 = generic or conflicting references. |
| Product Range and Engineering Capability | 10% | Available product categories, capacity range, component options, lifting configurations, drawings, and engineering support. | Current product catalogue, CAD or dimensional drawings, design calculations, sample-development procedure, and application guidance. | 5 = broad, documented range with engineering support; 1 = limited catalogue with no technical development capability. |
| Quality Management System | 8% | Quality-control structure, inspection points, nonconformance handling, corrective actions, calibration management, and internal audits. | Valid ISO 9001 certificate, quality manual, inspection plan, calibration records, and recent corrective-action examples. | 5 = certified system supported by operating records; 1 = certificate or process evidence unavailable. |
| Manufacturing and Capacity Reliability | 7% | Production equipment, monthly capacity, process capability, outsourcing ratio, maintenance program, and capacity during peak demand. | Factory audit, equipment list, production-flow records, capacity statement, maintenance logs, and representative delivery history. | 5 = capacity is documented and resilient; 1 = capacity depends mainly on unverifiable subcontracting. |
| Customization and Packaging Control | 8% | Custom dimensions, end fittings, coatings, labels, packaging, private documentation, inspection plans, and sample approval process. | Approved drawings, first-article inspection records, packaging specifications, label proofs, and documented engineering-change control. | 5 = controlled customization with formal approval; 1 = customization is informal or undocumented. |
| Export and Regulatory Readiness | 5% | Export documentation, packaging compliance, country-specific markings, multilingual instructions, customs support, and insurance documents. | Commercial invoices, packing lists, certificates of origin, test certificates, shipping records, and destination-market documentation. | 5 = complete documentation for the target market; 1 = repeated documentation gaps. |
| Delivery, Service, and After-Sales Support | 7% | Quotation response time, sample lead time, production lead time, on-time delivery rate, warranty terms, complaint response, and spare-part support. | Written service-level commitments, order-history data, warranty policy, complaint records, and reference checks from comparable projects. | 5 = measurable service performance with clear escalation; 1 = no defined service commitments. |
| Total Evaluation Score | 100% | Weighted score = Σ (criterion score ÷ 5 × criterion weight). | Rank only manufacturers that pass mandatory safety, testing, documentation, and traceability checks. | Suggested shortlist threshold: 70/100, subject to buyer risk requirements. |
