Prioritize location relative to ports and airports, warehouse layout for SKU velocity, IT integration (WMS/APIs), inbound/outbound carrier options, and value‑added services (kitting, returns). Also evaluate peak season capacity and SLA provisions for order accuracy and same/next‑day fulfillment.

Proximity to feeder ports and short-haul air links reduces ocean transits and enables faster reconsignment to regional markets. This typically lowers LTL and parcel zones, reduces buffer inventory needs, and offers more frequent sailings or flights to consolidate freight and negotiate better carrier rates.

Confirm 3PLs' bonded warehouse licensing, customs brokerage experience, and ability to segregate dutiable vs. non-dutiable stock. Verify documentation workflows, transit bond options, and timelines for customs clearance to avoid demurrage and speed order fulfillment to end customers.

Major cost drivers include storage density, labor productivity, inbound consolidation, and transportation lanes. Optimize by increasing pallet utilization, automating repetitive processes, consolidating inbound shipments, and negotiating multi-modal carrier contracts tied to volume commitments.

Assess a 3PL's flexible labor pools, temporary storage options, and ability to source additional capacity quickly. In contracts, confirm ramp-up SLAs, peak-season rate structures, inventory buffer policies, and exit terms to ensure predictable costs and service continuity during growth or seasonality.
