Prioritize port adjacency, bonded storage availability, average drayage times, throughput capacity, and proven customs clearance performance. Also assess IT integration (WMS/APIs), SLA on order lead times, inventory accuracy, and reverse logistics capabilities to control landed cost and improve fulfillment predictability.

Carrier access shapes transit windows: port-to-inland trucking reliability and airfreight frequency determine replenishment cadence. Evaluate multimodal options, carrier schedules, and local transshipment practices. Reliable liner services and predictable road haulage reduce stock buffers and enable tighter reorder points.

Expect line items for storage (per pallet/m3), pick-and-pack (per pick or per order), inbound/outbound handling, pallet manipulation, bonded storage fees, and customs brokerage. Request volume-tier pricing, minimum monthly charges, and clear demurrage or detention pass-throughs to compare true landed-cost scenarios.

Look for demonstrated expertise in import/export declarations, electronic manifesting, bonded operations, duty relief procedures, and sanitary/phytosanitary controls where applicable. Confirm the 3PL’s experience with local Customs authorities, pre-clearance workflows, and secure chain-of-custody for regulated goods.
