| Production Capacity | Documented capacity aligned with forecasted demand | 100,000–1,000,000+ finished units per month, depending on device type and production lines | Monthly capacity statement, production-line list, shift schedule, and recent capacity-utilization records | High Priority |
| Minimum Order Quantity | Flexible MOQ for product validation and market testing | Typically 1,000–10,000 units for standard products; higher for fully customized hardware | Written MOQ by model, flavor, packaging configuration, and regulatory market | Compare Carefully |
| Standard Product Lead Time | Predictable scheduling after artwork and specifications are approved | Approximately 15–35 working days for repeat orders, excluding shipping | Production schedule, historical on-time delivery rate, and order-to-shipment timeline | Core KPI |
| Custom Product Development | In-house engineering, prototyping, and design-for-manufacturing support | Prototype cycle commonly 7–30 days; mass-production tooling may require 30–90 days | Engineering team profile, prototype records, tooling ownership terms, and revision process | High Value |
| Customization Scope | Hardware, battery configuration, firmware, appearance, packaging, and documentation | Standard customization usually includes color, logo, packaging, airflow, coil, and e-liquid options | Customization matrix, approved-material list, sample approval procedure, and change-control policy | Verify in Writing |
| Quality Management | Controlled incoming, in-process, and final inspection procedures | Three-stage inspection model with documented acceptance criteria and batch traceability | Quality manual, inspection checklist, nonconformance procedure, and sample inspection report | Mandatory |
| Battery Safety Controls | Battery cells and charging components tested for transport and operational safety | Applicable UN 38.3 transport testing; electrical and battery documentation available by model | UN 38.3 test summary, Safety Data Sheet where applicable, battery specifications, and protection-circuit details | Mandatory |
| Product Compliance Support | Market-specific documentation prepared before shipment | Documentation varies by destination; may include test reports, declarations, labeling, and ingredient records | Country-specific compliance checklist, laboratory reports, labeling templates, and document-control records | Market Dependent |
| E-Liquid Batch Control | Controlled formulation, ingredient sourcing, and batch identification | Batch records should identify formula version, lot number, filling date, and release status | Ingredient specifications, supplier certificates, batch records, retention-sample policy, and laboratory testing scope | Audit Required |
| Defect Management | Transparent defect classification and corrective-action process | Agree an acceptable quality limit before production; use a documented sampling standard | Pre-shipment inspection criteria, defect photos, corrective-action reports, and replacement policy | Contract Item |
| Supply Chain Reliability | Multiple qualified sources for critical components | Dual-source planning recommended for batteries, coils, chips, packaging, and key raw materials | Business-continuity plan, approved supplier list, component lead times, and shortage-escalation procedure | Risk Reducer |
| Inventory Strategy | Safety stock and replenishment planning based on demand volatility | Common planning horizon: 30–90 days for critical components, subject to market conditions | Inventory policy, forecast-sharing process, reserved-capacity terms, and stock ownership agreement | Commercial Advantage |
| Export Logistics | Experience with battery-related shipping restrictions and export documentation | Shipping lead time varies by destination, transport mode, product classification, and customs requirements | Dangerous-goods shipping capability, packing specifications, commercial invoice, packing list, and transport documents | Destination Specific |
| On-Time Delivery | Consistent performance against confirmed purchase-order dates | Target at least 95% on-time shipment performance, measured over a defined reporting period | Shipment history, customer references, late-order log, and agreed service-level terms | Core KPI |
| Communication and Support | Dedicated account, engineering, and quality contacts | Response target within one business day for routine issues and immediate escalation for quality incidents | Account-management structure, escalation chart, development calendar, and after-sales procedure | Operational Fit |
| Commercial Transparency | Clear total-cost structure without hidden tooling, testing, or packaging charges | Quotation should separate product, tooling, testing, packaging, freight, duties, and payment terms | Formal quotation, incoterms, tooling ownership clause, payment schedule, and price-validity period | Decision Factor |
