Prioritize port proximity, feeder connectivity, storage type (ambient vs. controlled), throughput capacity, damage/loss handling, and documented SLAs for cut-off and delivery windows. Evaluate local carrier networks and contingency plans for seasonal weather disruptions.

Mainland-to-island transit determines safety stock and reorder points. Longer feeder or ferry schedules require higher buffer inventory or more frequent consolidation. Choose 3PLs with scheduled carrier slots and proven consolidation processes to minimize days of inventory outstanding.

Look for bonded/SEZ capabilities if cross-border flows exist, secure access control, racking and pallet handling suited to SKU density, temperature control where needed, inventory management systems (WMS) with API connectivity, and barcoding or RFID for rapid pick-and-pack.

Negotiate consolidation schedules, volume-tiered rates, shared distribution for slow movers, hybrid storage (on-demand overflow), and billing transparency for first/last-mile charges. Assess total landed cost including feeder surcharges, customs, and island-specific handling fees.

Evaluate on-time delivery metrics, carrier pickup frequency, proof-of-delivery methods, return handling workflows, and customer communication integrations. Confirm SLA compensation clauses and escalation paths for service failures to protect brand experience.
