Prioritize connectivity to ports and airports, bonded/FTZ capabilities, multi-temperature storage, and scalable slot capacity. Validate WMS integration, pick/pack throughput, receiving and reverse logistics processes, and measurable SLAs for order accuracy and lead times. Also assess local labor skillsets and contingency plans for seasonal peaks.

Carrier density and direct feeder links reduce handoffs and transit time variability. Proximity to coastal terminals and scheduled airfreight increases routing options and lowers multimodal transfer costs. Evaluate carrier mix, frequency, and negotiated rates to model landed cost and promised delivery windows.

Confirm the 3PL’s experience with bonded warehousing, FTZ procedures, customs declaration performance, and duty management. Check documentation workflows for import/export audits, tariff classification accuracy, and the provider’s track record on customs hold resolution to prevent clearance delays.

Require a modern WMS with APIs for carrier, OMS, and ERP integrations, real-time inventory feeds, and configurable rules for allocation and order routing. Look for scan-based receiving, automated fulfillment logic, and reporting dashboards that provide day-to-day operational metrics and exception tracking.
