  "sector": "transport-logistics",
  "summary": "Container shipping sells scheduled space in a global transport network. Profit depends on freight rates, loaded capacity, voyage costs, and how quickly ships and containers return to service.",
  "scope": "This profile covers scheduled ocean transport of standardized containers, including mainline and feeder services. Tankers, dry-bulk shipping, and port ownership are different businesses. Ocean carriers operate ships; freight forwarders may arrange transport without operating them. Safety rules are international, while commercial regulation and customs requirements vary by jurisdiction.",

    "Adding ships takes time, while freight demand and routing can change quickly. This mismatch helps explain why rates can move sharply even though physical transport technology changes slowly. A temporary detour absorbs vessel-days; restoring the shorter route releases effective capacity without delivering a new ship.",
    "Carriers can coordinate vessel capacity through contractual arrangements, but capacity sharing does not make every service interchangeable. Port coverage, schedule reliability, available equipment, and inland connections affect the total cost to a shipper.
