Evaluate multimodal connectivity (river, rail, expressway), proximity to inland port/bonded zones, carrier partnerships for regional last-mile networks, and the 3PL's cross-dock capabilities. Prioritize providers that demonstrate SLA performance, real-time WMS integration, and scalable slotting for peak seasons.

Key cost drivers include storage density, labor mix (manual vs automated), inbound/outbound handling fees, and transportation to major consumer corridors. Optimizing slot utilization, negotiating pooled freight rates, and selecting bonded or consolidation services can reduce landed costs while maintaining delivery windows.

Require a WMS with lot and batch tracking, EDI/API connectivity, cycle-count procedures, quality inspection processes, and defined KPIs (OTIF, inventory accuracy). Also assess reverse logistics processes and the 3PL's capacity to run scheduled cross-docks for high-frequency B2B lanes.

Look for proximity to bonded zones and inland ports, onsite customs brokerage, and 3PL experience with export consolidation. These features shorten customs clearance, enable duty deferral, and allow consolidation for ocean or rail export, lowering border dwell and transport cost.
