Prioritize order accuracy, pick-and-pack throughput, multi-temperature storage, returns processing, and real-time WMS/OMS integration. Also assess SLA commitments (OTIF, inventory accuracy), IT APIs for carrier and marketplace connectivity, scalability for peak seasons, and on-site value-adds like kitting or light assembly.

Wuxi generally offers lower rental and labor rates than central Shanghai and some Suzhou submarkets, reducing per-pallet storage and handling costs. Trade-offs include slightly longer drayage to the largest international port terminals, but total landed-cost can be lower due to operating efficiencies and shorter domestic distribution lanes.

Expect strong road trunk routes to regional hubs, rail intermodal options to northern and inland markets, air freight capability via Wuxi Shuofang for time-sensitive shipments, and drayage access to Yangtze port terminals. 3PLs typically integrate with major express couriers and freight forwarders for last-mile and international moves.

Negotiate clear SLAs for order accuracy, OTIF, inventory accuracy and lead times, plus chargeback mechanisms for non-compliance. Include seasonal capacity guarantees, transparent tariff schedules, data access and reporting standards, termination and transition support, and clauses covering force majeure and cybersecurity responsibilities.
