Prioritize carrier connectivity, port proximity, SLA metrics (order lead time, accuracy), warehouse automation, security and bonded storage. Also evaluate IT integration (API/EDI), inventory visibility, labor model and peak-season scalability to match your fulfillment profile.

Transit times influence buffer stock and reorder cadence. Consider feeder schedules to larger transshipment hubs, air freight windows, and last-mile carrier options. Align safety stock and multi-node inventory placement to mitigate variable feeder frequencies and optimize delivery promises.

Key cost drivers: warehousing (space, labor), pick-and-pack, inbound handling, duties and local transport. To optimize, negotiate volume tiers, use zone-based storage, consolidate inbound shipments, leverage bonded options and require transparent billing with unit-cost KPIs.

Verify customs brokerage capability, bonded warehouse options, product-specific regulations (food, pharma, electronics), and insurance limits. Recommended due diligence: review carrier contracts, customs processing times, certificate of insurance and evidence of regulatory audits.
