Prioritize WMS interoperability, pick-and-pack accuracy, scalable receiving and outbound throughput, returns processing, and SLA metrics. Validate integration with major carriers, EDI/API connectivity, inventory visibility, surge staffing plans, and compliance with cold chain or bonded requirements as relevant to your SKUs.

Close proximity reduces drayage and handling steps, shortens lead times to European and North African lanes, and lowers transit variability. It also enables more frequent carrier sailings and fewer intermodal transfers, which can reduce landed cost and improve predictability for export-focused operations.

Look for certified refrigeration systems, segregated ambient and cold zones, high-density racking, automated picking support, HACCP/compliance procedures, kitting and light assembly, and reliable backup power. Confirm operational KPIs, temperature monitoring, and traceability across the cold chain.

Assess the 3PL's customs brokerage capabilities, availability of bonded warehousing, import/export licensing, local VAT and duty handling, insurance coverage, and experience with required documentation. Also review labor regulations, contract language on liability, and dispute resolution terms.

Compare rate-card components (storage, receiving, picking, packing, outbound), minimums, handling rules for returns and damaged goods, billing cadence, and technology fees. Negotiate clear SLAs with KPIs and penalties, examine throughput assumptions, and request modeled P&L for your SKU mix and projected volumes.
