Prioritize measurable SLAs (order lead time, accuracy), WMS capabilities and API/EDI integrations, inventory visibility, pick/pack throughput, storage type (ambient, cold, bonded), cross‑dock capacity, returns processing, and labor flexibility. Also verify carrier access, dock infrastructure, and contingency plans for peak season.

Selecting a local 3PL reduces road miles to Kerala and southern Tamil Nadu consumer hubs and shortens last‑mile windows. Proximity to Thoothukudi port and regional air hubs lowers inbound/outbound drayage and ocean transit legs, allowing better consolidation and potentially lower LTL rates versus distant metropolitan warehouses.

Require a modern WMS with slotting and batch management, scalable racked storage and mezzanines, automated picking aids where applicable, temperature-controlled areas if needed, cross-dock and staging zones, and clear surge labor plans. Ensure real-time inventory visibility and carrier-routing tools for peaks.

Compare activity-based components: inbound receiving, storage (per pallet/cubic meter), pick/pack, packing materials, outbound handling, and accessorials. Model landed cost scenarios (volume tiers, seasonal peaks, returns) and require transparent reporting and chargebacks to align pricing with forecasted throughput.

Confirm availability of bonded warehousing and customs-broker relationships, validated export documentation procedures, and experience with container stuffing/stripping. Validate the 3PL’s knowledge of export licensing, HS code handling, and coordination with nearby port authorities to avoid clearance delays.
