Regional Approvals: CE marking (Europe), UL listing (North America), and other local certifications guarantee legal installation and insurance coverage.
3.2. Product Quality and Durability
Ingress Protection: Ratings of IP65 or higher protect stations from water jetting and dust ingress.
Materials: UV-resistant polycarbonate or powder-coated metal housings withstand outdoor exposure.
Connector Reliability: Robust connectors rated for thousands of mating cycles preserve long-term functionality.
3.3. Pricing Structures and Cost Components
Base Unit Price: Wholesale discounts often scale with volume tiers (e.g., 100+, 500+ units).
Accessory Bundles: Including cables, mounting hardware, and cable management add-ons can impact total cost-per-unit.
Shipping and Duties: Factor in freight (sea, air) and import duties, which vary by region and trade agreements.
3.4. Minimum Order Quantities (MOQs)
Volume Requirements: Understand the supplier’s MOQ thresholds and potential flexibility for staggered shipments.
Sample Orders: Negotiate lower MOQs for initial trial batches to validate product quality.
3.5. Lead Times and Inventory Planning
Production Lead Time: Typical manufacturing cycles range from 4–8 weeks, depending on customization and capacity.
Buffer Stock: Maintain safety stock levels to mitigate production delays and seasonal demand spikes.
3.6. Payment Terms and Financing Options
Deposit Structure: Common terms include 30% deposit, 70% balance before shipment.
Letter of Credit (L/C): Offers payment security for both buyer and seller in large-value transactions.
3.7. Warranty Policies and After-Sales Service
Warranty Coverage: Seek at least two years of comprehensive warranty, covering defects in materials and workmanship.
Service Network: Ensure the supplier has certified service centers or partner agreements for rapid troubleshooting and repairs.
3.8. Customization and Private Labeling
Branding Options: Custom logos, color schemes, and packaging designs strengthen reseller identity.
Software Customization: Pre-loaded firmware settings, app white-label solutions, and custom user interfaces.
3.9. Logistics and Shipping Considerations
Packaging Quality: Robust crates or palletized packaging prevent damage during long-distance transit.
Transportation Modes: Evaluate cost vs. speed—sea freight for cost efficiency, air freight for urgent restocks.
3.10. Supplier Reputation and Stability
Company History: Longevity and consistent performance indicate reliability.
Financial Health: Stable cash flow and capacity to scale production reduce risk of supply interruptions.
