Prioritize location proximity to key transport nodes, demonstrated cold‑chain capability (if relevant), WMS/API integration, SLA and KPI transparency, peak‑season scalability, and documented last‑mile carrier relationships. Consider physical layout (racking, cross‑dock space), turnaround times, and inventory accuracy history to align with your service and cost targets.

Verify dedicated temperature‑zoned storage, uninterrupted power and backup refrigeration, 24/7 temperature monitoring, trained handling staff, and documented cleaning/pest control regimes. Request certification evidence such as HACCP or ISO food safety records, ATP test results for refrigerated transport, and sample temperature logs for inbound/outbound shipments.

Using a Heilongjiang 3PL often lowers warehousing and handling costs and improves service to northern and cross‑border markets, but may increase transit time and freight costs to southern coastal customers. Evaluate demand density, inventory placement strategy, and potential rail consolidation options to balance lead times against lower occupancy and labor costs.

Require a modern WMS with API/EDI connectivity, real‑time inventory feeds, order management for multi‑channel routing, and reporting dashboards. Ensure the 3PL offers a sandbox for integration testing, documented SLAs for data exchange, role‑based access controls, and routine reconciliation processes to maintain inventory accuracy across sales channels.
