Focus on port proximity, direct access to national expressways, and rail/road interchanges. Evaluate carrier density (ocean, LTL, TL), customs/bonded options, and the 3PL's experience with export documentation. Also compare lead times to major domestic markets and typical freight rates to forecast landed cost.

Assess WMS functionality (API, inventory visibility, and EDI), pick/pack accuracy, returns processing SLA, and slotting efficiency. Compare pricing models: storage by pallet vs. cubic meter, outbound pick fees, and value‑added service rates. Request performance KPIs and a sample billing run to validate total cost of fulfillment.

Confirm temperature control ranges, monitoring and alarm integrations, and contingency power. Verify bonded warehouse licensing, customs facilitation, and hazardous goods certifications (class handling, segregation, and documentation). Inspect SOPs for traceability and recall management.

Map demand centers and inbound supplier origins to minimize cross‑dock and last‑mile costs. Use slotting strategies aligned to SKU velocity, set reorder points based on transit variability, and choose 3PLs with flexible racking, short lead times, and proven capacity for seasonal surge handling.
