Prioritize proven multimodal carrier relationships, predictable shipping windows, robust WMS with API access, cold‑chain capability if required, and documented contingency plans for weather‑related delays. Verify insurance, lead‑time modeling, and returns processing to align with your service levels and inventory strategy.

Expect fewer sailings and flights, higher per‑shipment handling charges, and greater price sensitivity to consolidation. Use weekly service schedules, buffer inventory, and zone‑based landed‑cost models to capture true total cost and avoid service gaps caused by seasonal disruptions.

Require climate‑controlled storage, backup power, validated temperature monitoring, secure receiving and quarantine areas, and traceability via WMS. Depending on cargo, look for ISO certifications and documented biosecurity procedures, as well as experience with customs, permits, and specialized packaging protocols.
