| 1 | Product Safety and Compliance | Material declarations, safety data sheets, restricted-substance testing, battery transport documents, and applicable market compliance records. | Complete, traceable documentation for every model and target market; no unexplained compliance gaps. | 18% |
| 2 | Flavor Consistency | Batch records, flavor approval samples, raw-material lot tracking, and retained-sample procedures. | Approved flavor profile remains consistent across production batches, with documented corrective action for deviations. | 14% |
| 3 | Airflow and Heating Performance | Measured airflow, activation response, heating stability, leakage checks, and output consistency from pre-shipment testing. | Stable draw activation and repeatable output under the agreed test conditions and usage profile. | 12% |
| 4 | Battery and Electrical Reliability | Battery-cell traceability, charging protection, short-circuit testing, storage testing, and aging-test records. | Protection functions are verified, cells are traceable, and failure rates are monitored through documented quality records. | 12% |
| 5 | Leakage and E-Liquid Control | Filled-unit inspection records, seal design validation, transport simulation, and shelf-life or storage testing. | No visible leakage during approved handling and transport tests; filling volume is controlled by documented procedures. | 10% |
| 6 | Manufacturing Capacity | Verified production lines, monthly capacity statements, equipment list, staffing structure, and capacity-allocation records. | Capacity is sufficient for the forecast volume without reducing inspection, traceability, or delivery performance. | 8% |
| 7 | Quality Management System | Process-control plans, incoming inspection, in-process inspection, final inspection, nonconformance records, and corrective-action reports. | Quality controls are documented, repeatable, and supported by auditable production records. | 10% |
| 8 | Customization Capability | Available options for flavor formulation, airflow design, shell color, packaging, labeling, and user instructions. | Can provide samples, controlled engineering changes, and documented approval before mass production. | 6% |
| 9 | Lead Time and Supply Reliability | Written production schedule, sample lead time, repeat-order lead time, on-time delivery history, and contingency planning. | Typical sample development is completed within an agreed project schedule, with clear escalation procedures for delays. | 5% |
| 10 | After-Sales Support and Transparency | Warranty terms, replacement policy, complaint-response process, product-change notification, and communication records. | Provides written service terms, responds promptly to quality issues, and discloses material or process changes before shipment. | 5% |
