TAMP (major port tariff authority) regulation
What it is
The Tariff Authority for Major Ports historically set rates at government-owned major ports, while private and state ports priced freely. Reform has progressively freed major port tariffs, moving toward market determination
It created a long-standing regulatory asymmetry between major and non-major ports
Impact on industries
- Regulated tariffs at major ports capped their returns while private ports priced freely, which is a principal reason private ports gained share
- Tariff liberalisation lets major ports compete on service and pricing rather than being structurally disadvantaged
- The asymmetry shaped the industry's structure for two decades, so its removal changes competitive dynamics only gradually
- Concession terms and revenue-share obligations remain the binding commercial constraint at many terminals regardless of tariff freedom
