Prioritize WMS/OMS integration, real-time inventory visibility, pick-and-pack accuracy, SLA-backed lead times, returns and reverse-logistics processing, kitting and value-added services, temperature-controlled storage if needed, and demonstrated carrier connectivity for last-mile delivery.

Expect lower local real estate and handling costs for smaller footprint operations but potential island-specific transport premiums on inbound consolidation and late-stage distribution. Cost drivers include frequency of feeder services, consolidation requirements, bonded handling, and carrier access.

Focus on port depth and transshipment schedules, short-sea and Ro-Ro frequency, feeder service reliability, airport cargo lanes for time-critical shipments, and robust multimodal links to connecting hubs to minimize dwell and transfer times.

A qualified 3PL should offer bonded warehousing, customs brokerage, VAT/duty handling, EORI facilitation, secure documentation workflows, and fast customs clearance procedures to reduce border friction and support import/export compliance.
