Assess multimodal connectivity (road/rail/port drayage), carrier density and linehaul frequency, WMS capabilities and integration, scalable floorplate and labor flexibility, plus availability of value‑added services (kitting, returns). Prioritize 3PLs with transparent cost models and measurable SLA reporting.

Shorter drayage to Bilbao and Santander reduces inland transport charges and customs handling time, enabling faster container turn and consolidation options. That proximity supports multiple routing choices, lowers inventory days of supply, and often reduces overall landed cost through improved modal mix.

Key infrastructure includes racking density, pick module design, packing stations, conveyor and sortation systems, and integration with a modern WMS. Services such as zone picking, batch scheduling, and returns processing materially improve throughput and reduce order cycle variability.

Negotiate clear SLAs (OTIF, order accuracy, inventory accuracy), tiered pricing by throughput and storage duration, chargeback policies, minimum volume commitments, termination notice, and regular operational reporting cadence. Include liabilities, insurance coverage, and escalation processes in the contract.
