Prioritize throughput (picks per hour), storage density, order SLA options, integration with your OMS/WMS, bonded and customs processing if doing cross-border, and carrier connectivity for air, rail and local last‑mile. Also check seasonal scalability, SLA penalties, and visibility tools for tracking and reporting.

Proximity to Chengdu airports and intermodal rail reduces inland transits and enables faster air-to-rail options, lowering multimodal leg costs and time-in-transit to western provinces and ASEAN routes. That access shortens replenishment cycles and can reduce safety stock and overall landed cost.

Look for bonded and customs clearance capabilities, HACCP or ISO certifications for food and pharma, temperature‑controlled facilities for cold-chain, documented QA processes for returns handling, and clear traceability in the WMS for lot and SKU control.

Compare unit storage rates, pick/pack and handling fees, inbound receiving and cross-dock charges, order minimums, equipment surcharges, billing cadence, and any integration or onboarding costs. Model total cost-to-serve by SKU, including transport to final destinations and seasonality impacts.
