Prioritize WMS integration, inventory accuracy, pick-and-pack productivity, cold-chain handling if required, returns processing, kitting/assembly, and SLA-backed lead times. Also verify carrier interfaces, EDI/API connectivity, and the 3PL’s experience managing seasonal demand spikes tied to fishing and tourism cycles.

Deliveries within Alaska rely on barge, ferry, and air options and usually have higher per-unit transport costs and longer transit windows than the Lower 48. Cross-border flows transit Seattle for consolidation. Mitigation strategies include forward-stocking in Juneau, ocean or barge consolidation, zone-skipping to reduce handling, and multi-modal routing to balance cost and lead time.

Key factors are port berth availability, scheduled feeder barge and ferry services, air cargo frequency, warehouse loading capacity, and local drayage. Limited road networks increase reliance on maritime/air schedules, so established carrier contracts and validated contingency plans are essential for predictable B2B service.

Evaluate peak versus off-peak storage rates, labor availability, lead times for inbound replenishment, and the 3PL’s ability to scale temporary space. Model total landed cost including consolidation, air uplift, and stockout risk; consider seasonal contracts or flexible capacity clauses to control costs while maintaining service levels.
