Focus on carrier connectivity (ocean, air, road, rail), proximity to major terminals, bonded/FTZ availability, proven WMS/OMS API integrations, SLA metrics (pick accuracy, lead time), value-added services (kitting, returns), scalability of space and labor, and transparent tariff/pricing structures to avoid hidden fees.

Bonded and FTZ facilities allow deferred duty payment, enable inventory consolidation, and support triage of goods (inspection, labeling, kitting) before customs entry. These features reduce immediate cash outflow, enable tariff-efficient routing, and simplify returns or re-exports, improving landed-cost management for cross-border sellers.

Pricing typically includes storage (per pallet/sq m), receiving and put-away, pick-and-pack per-order and per-line fees, outbound handling, value-added services, monthly minimums, and pass-through charges (demurrage, detention, local taxes). Ask for sample invoices and SLA-linked rebates to compare total landed-cost impact.

Domestic truck transit to Shanghai typically ranges from same-day up to 3–4 days depending on origin; rail from western provinces can be 7–12 days. Allow additional port dwell and consolidation lead time for exports. Use safety stock calibrated to supplier variability, port cutoffs, and 3PL throughput constraints to avoid stockouts.

Require real-time inventory visibility, WMS with API/EDI connectivity to your OMS/platform, automated shipment notifications, barcode scanning and lot/expiry control if needed, returns management, and reporting on SLA KPIs (OTIF, pick accuracy). Confirm sandbox access and documented integration timelines before onboarding.
