Prioritize multimodal connectivity (port, road, rail where available), bonded storage, WMS capabilities (real-time visibility, EDI), proven SLA and KPI reporting, secure workforce availability, and an experienced customs brokerage to reduce delays and total landed costs.

Bonded facilities allow deferred duties and faster domestic movement; however, local documentation, inspection windows, and customs cycles affect lead times. Work with 3PLs that provide in-house brokerage, compliant paperwork handling, and transparent duty projections to manage landed cost and avoid clearance delays.

Expect pick-and-pack, kitting, returns processing, temperature-controlled storage, and cross-dock capabilities. Match service tiers to channel needs: high-velocity eCommerce needs rapid pick/pack and shipping integrations; B2B often requires pallet storage, scheduled LTL/FTL shipments, and ASN/EDI support.

Select 3PLs close to primary ports or main arterial roads to reduce handoff times, verify established contracts with regional carriers and integrators for consistent capacity, and prefer partners offering cross-dock and multi-carrier tendering to optimize transit windows and reduce dwell.
