Prioritize WMS/API integration, SLA performance, and dock capacity. Evaluate cold chain and value-added services (kitting, returns), the 3PL's carrier lane coverage via Chiang Mai consolidation, scalability for peak seasons, and local labor availability to sustain picking accuracy and throughput.

Direct transport from Mae Hong Son typically has longer road transit to central hubs, but lower local operating costs. Carrier access is strengthened through consolidation at Chiang Mai for better national and international lanes; air options are limited, so plan for road-based consolidation and managed carrier networks.

Look for modular racking, flexible footprint options (shared and dedicated space), documented peak staffing plans, cross-dock capability, battery-backed dock staging, and a WMS with slotting and labor management. These elements reduce ramp time and preserve service levels during growth.

Account for customs procedures for northern border trade, required permits, and documentation. Engage 3PLs experienced in export/import compliance, bonded warehousing if needed, and who provide customs brokerage or coordinated consolidation to minimize border delays and duty misclassification risks.
