Prioritize multimodal transit lanes, bonded and temperature-controlled capacity, clear customs experience, and carrier integrations. Evaluate KPIs (OTD, pick accuracy, dwell time), IT compatibility (WMS/APIs), and scalability to absorb seasonal peaks without degrading service levels.

Tapachula's proximity to Pacific ports and highway corridors shortens ocean-to-warehouse and last-mile legs, reducing drayage and inland transit costs. Carrier density supports competitive rates and routing options, improving transit predictability and lowering total landed cost.

Confirm certified temperature zones, validated monitoring and alarm systems, backup power, HACCP or relevant certifications, and bonded status for deferred duties. Also assess handling equipment, pallet configurations, and segregation options to avoid cross-contamination and ensure compliance.

Request performance data on throughput and seasonal scaling, WMS functionality and API readiness, EDI or API integration examples, and onboarding timelines. Validate real-time inventory visibility, exception workflows, and SLA penalties to ensure the partner supports omnichannel velocity.

Confirm bonded warehouse credentials, customs broker relationships, local tax/tariff treatment, import/export documentation handling, and compliance with sanitary and phytosanitary requirements where applicable. Ensure the 3PL has documented procedures for audits and dispute resolution.
