Prioritize network footprint (port-proximate vs inland), slot availability for peak season, WMS integration and API capability, SLA commitments for pick/pack/ship, inventory accuracy metrics, reverse logistics processes, and value-added services (kitting, labeling, bonded operations). Also review carrier relationships and export handling experience.

Port proximity shortens port-to-warehouse moves and supports consolidated export windows; rail links reduce transit to Beijing–Tianjin and northeastern manufacturing centers; highways enable fast last-mile domestic delivery. Combined access to ocean feeders, rail corridors and road carriers increases routing flexibility and can tighten lead-time variability.

Look for pick-and-pack efficiency, same-day cutoffs, inventory visibility via WMS, automated replenishment, parcel carrier integrations, returns processing workflows, and cold-chain handling if needed. Bonded warehousing and customs expertise are important for cross-border sellers to reduce duty-processing delays.

Warehouse rents and on-site labor in Qinhuangdao are generally more competitive than prime urban centers like central Beijing or Tianjin, but costs vary by facility class, port access, and specialized services (cold storage, bonded). Total landed cost should include handling fees, drayage, and customs processing when benchmarking.

A credible 3PL should show established relationships with ocean carriers and feeder services, rail operators for inland links, local trucking networks, and experienced customs brokerage or bonded yard arrangements. Clear EDI/WMS integrations and documented export handling procedures reduce dwell time and improve freight routing options.
