| Product Definition | Confirm whether “crystal” refers to crystal glass, tempered glass, laminated glass, engineered quartz, or another material. | Material specification clearly stated | Technical datasheet, material declaration, sample label, and approved drawing | 10% |
| Glass Safety | For glass tabletops, verify heat-treatment quality, edge finishing, impact resistance, and safe breakage characteristics. | Tempered glass tested to the applicable market standard | Tempering records, inspection reports, and applicable EN 12150 or equivalent test documentation | 15% |
| Dimensions and Tolerances | Review tabletop length, width, thickness, hole positions, flatness, and frame alignment against the approved drawing. | Written tolerances for every critical dimension | Signed drawings, dimensional inspection report, and first-article sample | 12% |
| Surface and Edge Quality | Inspect polishing, bevels, corners, surface scratches, bubbles, inclusions, color consistency, and visible optical distortion. | No sharp edges, cracks, chips, or unacceptable visible defects | Defect classification standard, inspection photos, and production samples | 12% |
| Structural Design | Evaluate the stability of the base, joints, fasteners, load-bearing points, anti-tip features, and compatibility of glass with the frame. | Stable under the buyer’s specified static and handling loads | Assembly drawings, load test results, joint specifications, and sample inspection | 15% |
| Material Compliance | Check whether coatings, adhesives, metals, packaging materials, and other components meet the destination-market requirements. | Applicable chemical and product requirements documented | REACH or RoHS declarations where applicable, safety data, and third-party test reports | 10% |
| Quality Management | Assess documented control of incoming materials, production checks, final inspection, corrective actions, and traceability. | Documented quality system with batch traceability | Quality manual, inspection checklist, corrective-action records, and valid ISO 9001 certificate if claimed | 10% |
| Production Capacity | Verify whether the facility can handle the required size, finish, quantity, packaging method, and repeat-order schedule. | Capacity supported by actual equipment and production records | Factory audit, equipment list, production plan, and recent non-confidential capacity records | 8% |
| Customization Capability | Review capability for custom shapes, thicknesses, colors, printing, metal finishes, bases, packaging, and private specifications. | Prototype approval before mass production | Prototype, signed sample approval, engineering change procedure, and tooling quotation | 8% |
| Packaging and Export Readiness | Check protection against glass breakage, abrasion, moisture, vibration, and incorrect handling during international transportation. | Export packaging validated by drop or handling tests | Packaging specification, carton or crate photos, packing list, and trial-shipment feedback | 5% |
| Lead Time and Delivery Control | Compare sample lead time, production lead time, inspection time, shipping readiness, and the supplier’s ability to communicate delays. | Written schedule with milestone dates | Proforma invoice, production schedule, shipment records, and agreed delay procedure | 3% |
| Commercial Terms and After-Sales Support | Evaluate payment terms, warranty scope, replacement policy, spare parts, claims handling, and responsibility for confirmed defects. | Clear written warranty and claims process | Sales contract, warranty terms, replacement procedure, and documented communication channel | 2% |
