| Quality Management System | Documented quality procedures covering incoming materials, production, inspection, nonconformities and corrective actions. | Current quality manual, process flowcharts, internal audit records and corrective-action logs. | Creates consistent production controls and reduces dependence on individual employees. | Before onboarding and during annual supplier reviews. |
| Batch Traceability | Every finished unit should be traceable to a production batch, component lot, production date and inspection record. | Sample batch records, lot-code format, inventory records and mock recall results. | Supports targeted recalls and faster investigation of complaints or defects. | Each shipment and after any process change. |
| Product Testing | Testing should address battery safety, leakage, charging performance, activation, e-liquid composition and package integrity as applicable to the product. | Finished-product test plans, laboratory reports, acceptance criteria and retained samples. | Detects safety and performance issues before products reach distributors or consumers. | During pilot production, routine production and after design changes. |
| Battery and Transport Compliance | Lithium-ion cells and batteries intended for transport should be evaluated against applicable transport requirements, including UN 38.3 testing where required. | UN 38.3 test summary, battery specifications, safety test reports and transport packaging documentation. | Reduces shipping delays, rejected consignments and battery-related logistics risks. | Before the first shipment and whenever the battery design changes. |
| Regulatory Readiness | The manufacturer should identify market-specific requirements, such as premarket authorization in the United States and notification, labeling and product limits under the European Union Tobacco Products Directive. | Regulatory checklist, technical file index, ingredient information, labeling review and market-specific responsibility matrix. | Prevents avoidable compliance gaps and supports lawful market entry. | At project launch and whenever regulations or target markets change. |
| Change Control | Material, supplier, firmware, heating element, battery or packaging changes should be documented and approved before implementation. | Engineering-change notices, approval records, risk assessments and validation results. | Maintains consistent product performance across production cycles. | For every proposed change. |
| Production Capacity | Available capacity should cover forecast demand while preserving inspection, maintenance and lead-time controls. | Capacity plan, equipment list, staffing plan, historical lead-time data and production schedule. | Improves supply continuity during seasonal demand or product launches. | Quarterly and before major purchase orders. |
| Defect and Complaint Management | Track defect rate, return rate, complaint categories, root causes and corrective-action closure time using an agreed reporting format. | Monthly quality dashboard, complaint database, root-cause analysis and corrective-action status. | Turns customer feedback into measurable product and process improvements. | Monthly during active production. |
| Supply Chain Resilience | Critical components should have approved specifications, qualified suppliers and documented alternatives where feasible. | Approved supplier list, component specifications, incoming inspection records and continuity plan. | Reduces disruption caused by shortages, substitutions or supplier failure. | Quarterly and after major supply-chain events. |
| Communication and Reporting | Define named contacts, escalation routes, reporting intervals, approval points and response expectations in the manufacturing agreement. | Communication matrix, meeting schedule, production reports and escalation procedure. | Improves decision-making and prevents delays caused by unclear responsibilities. | Reviewed at contract signing and during quarterly business reviews. |
| Partnership and Continuous Improvement | Use shared key performance indicators for quality, delivery, responsiveness, cost and corrective-action performance. | Quarterly business review materials, improvement plans and agreed performance trends. | Builds a stable long-term relationship instead of relying only on price comparisons. | Quarterly, with an annual strategic review. |
