Evaluate road and rail access to Helsinki and cross-border corridors, port and inland terminal options, dock capacity, and proximity to major carrier lanes. Consider customs processing time, multimodal transfer points, and typical transit times to primary markets when comparing 3PL locations and service levels.

Compare storage (per pallet/bin), handling (per pick/pack), inbound receiving, value-added services (kitting/assembly), and outbound freight allocation. Factor in minimums, billing cadence, shrink/obsolescence policies, and expected cost-per-order to model total landed cost against service-level requirements.

Customs clearance windows, documentation accuracy, and bonded vs. non-bonded storage affect lead times. Assess a 3PL's experience with export/import filings, preferred carrier customs lanes, and contingency plans for delays to ensure predictable order cycles for cross-border shipments.

Require a modern WMS with API/EDI connectivity, real-time inventory visibility, and transaction-level reporting. Key KPIs include inventory accuracy, order cycle time, on-time fulfillment rate, and cost-per-pick. Confirm the 3PL's capacity to scale labor and rack space seasonally without degrading SLA performance.
