Evaluate carrier frequency and reliability (ferries, feeder vessels, airports), IT integration (WMS/TMS/APIs), seasonal capacity planning, SLA performance for pick‑pack and returns, and local value‑added services such as cold storage and kitting. Prioritize partners with proven surge management and visibility tools.

Regular ferry and feeder schedules shorten connector legs to main shipping routes and reduce reliance on costly ad‑hoc transport. Airport links provide express options for urgent SKUs. Both modal choices affect landing costs, consolidation opportunities, and last‑mile complexity to resorts and island retail points.

Look for temperature‑controlled storage with documented HACCP/food safety procedures, bonded storage if needed, traceability systems, customs facilitation, and capacity for light processing or rework. Certifications and audited cold chain processes reduce spoilage and regulatory risk.

Negotiate flexible volume tiers and surge clauses, use shared or multi-client warehousing, pre-position inventory ahead of peak season, coordinate inbound schedules with carriers, and invest in demand forecasting with your 3PL to secure slot allocations and temporary labor plans.
