Evaluate port proximity, bonded/free‑zone options, customs facilitation times, available carrier lanes, and the 3PL's experience with your product categories. Also review SLA uptime, pick/pack accuracy, lead times, and value‑added services (kitting, temperature control) that impact cost‑to‑serve and customer experience.

Bonded zones can defer duties and reduce cash flow impact while faster customs clearance and port proximity lower dwell time and expedite replenishment cycles. Together these factors cut inventory holding costs, shorten order‑to‑delivery timelines, and improve responsiveness to demand spikes.

Include required storage types (ambient, chilled, frozen), throughput capacity (daily picks/lines), SLA targets (order lead time, picking accuracy), technology stack (WMS, EDI/API), labor model, contingency plans, insurance limits, and transparent cost components (storage, handling, inbound/outbound fees).

Confirm multi‑carrier connectivity for ocean, regional feeder services, road and rail terminals, and local last‑mile networks. Assess container frequency, inland haul costs, transit variability, and the 3PL's partnerships with local carriers to ensure predictable delivery windows and competitive freight rates.
