Requirements vary by jurisdiction; for example, the European Union limits nicotine-containing e-liquid in consumer refill containers to 20 mg/mL under the Tobacco Products Directive. | Independent laboratory assay results, batch specifications, calibration records, and certificates of analysis for finished products. | Critical | Mislabeling, consumer safety concerns, regulatory non-compliance, or inconsistent product performance. |
| Ingredient Control | Define approved ingredients, prohibited substances, purity requirements, allergen controls, and supplier qualification procedures. Ingredients should be suitable for the intended inhalation product and supported by traceable documentation. | Full ingredient list, supplier specifications, safety data sheets, certificates of analysis, incoming-material inspection records, and change-control documents. | Critical | Contamination, unexpected emissions, recalls, or inability to demonstrate product safety. |
| Device Electrical Safety | Specify battery chemistry, charging method, input and output limits, overcharge protection, over-discharge protection, short-circuit protection, and temperature-control requirements where applicable. | Electrical safety test reports, design validation records, protection-circuit test results, charger compatibility data, and samples from production batches. | Critical | Overheating, fire, explosion, electric shock, or dangerous device malfunction. |
| Battery and Transport Safety | Require appropriate lithium-battery testing and transport documentation. Lithium-ion cells commonly require evidence of compliance with the UN Manual of Tests and Criteria, Part III, Sub-section 38.3, for transport purposes. | UN 38.3 test summary, battery specifications, shipping classification, packaging instructions, and transport inspection records. | Critical | Shipment delays, dangerous-goods violations, rejected cargo, or increased fire risk during transport. |
| Product Construction and Leakage Control | Define tank or pod capacity, material compatibility, seal design, airflow range, filling method, leak-rate acceptance criteria, and drop or vibration resistance. | Engineering drawings, material declarations, leak-test results, dimensional inspection reports, drop-test records, and production samples. | High | Liquid leakage, damaged packaging, poor user experience, or exposure to nicotine-containing liquid. |
| Emissions and Chemical Testing | Set a testing plan for aerosol emissions and potentially harmful substances relevant to the formulation and device design. Testing should be performed using defined operating conditions and validated analytical methods. | Independent laboratory reports, test-method descriptions, detection limits, sample-conditioning records, and comparison with applicable market thresholds. | Critical | Unidentified chemical hazards, failed regulatory review, or unsupported safety claims. |
| Manufacturing Quality System | Use documented procedures for production, sanitation, inspection, non-conforming products, corrective actions, training, and record retention. ISO 9001 certification can support quality-system evaluation but does not by itself prove product compliance. | Quality manual, process procedures, internal-audit reports, training records, corrective-action logs, and current certification scope. | High | Inconsistent batches, undocumented deviations, recurring defects, and weak accountability. |
| Batch Traceability | Ensure every finished product can be linked to raw materials, production date, equipment, operators, inspection results, packaging, and distribution records. | Batch-number structure, electronic or paper batch records, warehouse logs, recall simulation results, and retention policy. | High | Slow or incomplete recalls and inability to isolate affected products. |
| Packaging and Child-Resistant Features | Define child-resistant requirements, tamper evidence, leak resistance, container compatibility, and packaging durability according to the destination market. Where applicable, use recognized child-resistant packaging test procedures. | Packaging test reports, closure specifications, tamper-evidence validation, artwork approval records, and production-line inspection results. | Critical | Accidental exposure, packaging failure, legal non-compliance, or product withdrawal. |
| Labels and Consumer Information | Require accurate nicotine declarations, ingredient information, warnings, batch identification, manufacturer or responsible-party details, storage guidance, and disposal instructions as required by the target market. | Regulatory label review, approved artwork, translation review, barcode verification, and print-quality inspection records. | Critical | Misleading information, rejected shipments, consumer complaints, or regulatory penalties. |
| Marketing and Product Claims | Prohibit unsupported claims such as “risk-free,” “healthy,” “safe,” or therapeutic claims unless specifically authorized and substantiated under the relevant legal framework. Avoid youth-oriented imagery and unauthorized health comparisons. | Claim-substantiation file, legal review, approved advertising materials, digital-content monitoring, and documented marketing controls. | Critical | Advertising restrictions, enforcement action, reputational damage, or removal from sales channels. |
| Supplier Qualification | Assess critical suppliers for materials, batteries, coils, packaging, and laboratories. Require consistent specifications and formal notification before any material or process change. | Supplier questionnaires, audit reports, approved-supplier list, certificates, performance scorecards, and change-notification agreements. | High | Uncontrolled variation, counterfeit components, supply interruptions, or hidden compliance failures. |
| Independent Testing Capacity | Use laboratories with suitable competence, impartiality, and documented methods. ISO/IEC 17025 accreditation is a useful indicator for laboratory competence, but the accreditation scope must cover the relevant tests. | Current accreditation certificate, scope of accreditation, laboratory quality records, raw data, and signed final reports. | High | Unreliable results, failed market review, or inability to defend technical claims. |
| Pre-Production and Final Inspection | Establish measurable acceptance criteria for appearance, dimensions, resistance, airflow, charging, activation, output consistency, leakage, packaging, and labeling. | Approved reference samples, inspection checklists, sampling plans, inspection records, and release authorization. | High | Defective products reaching customers and increased returns or complaints. |
| Complaint Handling and Recall Readiness | Maintain a documented process for complaints, adverse incidents, safety investigations, regulatory notifications, product correction, and recall execution. | Complaint register, escalation procedure, recall plan, mock-recall results, root-cause analyses, and corrective-action records. | High | Delayed response to safety events and increased consumer or regulatory impact. |
| Production Capacity and Continuity | Confirm realistic monthly capacity, lead times, minimum order quantities, critical-material inventories, backup suppliers, and business-continuity arrangements. | Capacity plan, production schedule, inventory policy, business-continuity plan, and documented manufacturing-location details. | Medium | Late deliveries, rushed production, inconsistent quality, or extended stockouts. |
| Contract and Change Control | Define responsibilities for compliance, testing, intellectual property, confidentiality, defects, recalls, audit rights, change approval, and record retention before production begins. | Signed quality agreement, manufacturing contract, technical file index, change-control form, and responsibility matrix. | High | Disputes, unauthorized changes, unclear liability, or loss of critical technical records. |
| Supplier Audit and Ongoing Review | Audit the manufacturer before approval and periodically thereafter, with additional reviews after serious complaints, process changes, or regulatory updates. | Audit plan, audit checklist, findings register, corrective-action deadlines, closure evidence, and periodic supplier-performance review. | High | Quality deterioration or compliance gaps remaining undetected. |
| Regulatory Monitoring | Assign responsibility for monitoring changes in product rules, packaging requirements, battery transport rules, labeling obligations, taxes, and market restrictions. | Regulatory update log, review schedule, compliance responsibility matrix, and documented impact assessments. | Medium | Products becoming non-compliant after regulatory changes. |
