Evaluate inventory management, pick-and-pack accuracy, order fulfillment SLA times, returns processing, temperature-controlled storage if needed, customs brokerage capabilities, and carrier integrations. Also review scalability, reporting/visibility tools, and local knowledge of port and air schedules.

Transit times depend on feeder schedules and air connections to hubs like Guam or regional Asia-Pacific airports. Fewer direct services can increase lead times and per-unit freight cost, so consolidation, optimized routing, and reliable feeder partnerships are key to predictable landed cost.

Confirm the 3PL's experience with local customs procedures, bonded or duty-deferral options, import/export documentation, classification accuracy, and any special permits. Ensure they provide electronic documentation and audit trails for compliance and duties optimization.

Look for flexible pick-and-pack setups, efficient reverse-logistics workflows, real-time inventory synchronization across channels, SLA-based reporting, and the ability to manage refurbished or returned goods disposition to limit holding costs and speed resale.
