Evaluate physical footprint (racking, climate control), proximity to ports/borders, IT and EDI capabilities, SLA and KPI reporting, customs and compliance expertise, inbound/outbound carrier relationships, and ability to support returns and value-added services. Prioritize partners with measurable accuracy and clear escalation procedures.

Costs vary by proximity to ports and major highways: port-adjacent locations often incur higher rent but lower transit costs. Expect longer lead times for inland distribution due to road conditions. Budget for customs clearance fees, handling charges, local transportation, and contingency for seasonal variability.

Seek real-time WMS visibility, EDI/API integrations for order and shipping flows, barcode/RFID scanning for inventory accuracy, batch/Lot tracking for compliance, and reporting dashboards for KPIs. Verify integration support with marketplaces, ERPs, and major carriers to reduce manual touch and errors.

Key risks include inconsistent documentation, tariff classification errors, delays in customs inspections, and variable processing times. Choose 3PLs with in-house customs brokerage, documented clearance workflows, and experience with HS codes, duty mitigation, and required permits to reduce disruption.
