Evaluate by: warehouse footprint and racking density; pick-pack and returns processing capabilities; carrier and port connectivity; customs and bonded warehouse services; technology stack (WMS, EDI/API) and KPI transparency. Prioritize providers that demonstrate scalable labor models and clear SLA/KPI reporting for on-time delivery and inventory accuracy.

Port proximity reduces ocean-to-warehouse transfer time; reliable road corridors improve inland delivery windows; available carrier interchanges lower last-mile complexity. Together these factors can cut inventory-in-transit days and decrease landed costs through reduced demurrage, shorter routes, and consolidated cross-dock opportunities.

Confirm licensed customs brokerage, bonded storage options, experience with import/export documentation, and local compliance processes. Also verify ISPS/port security alignment, duty deferral procedures, and the 3PL’s track record with inspections and release times to avoid unexpected delays and costs.

Typical KPIs include order accuracy, on-time shipping, dock-to-stock time, and inventory accuracy. Expect minimum monthly throughput or pallet commitments for competitive rates. Request SLA remedies, transparent chargeback terms, and system integrations (WMS/API) to ensure operational visibility and reliable performance.
