Two centuries after King Dom João VI opened Brazil’s ports to “friendly nations,” the state of Rio de Janeiro is trying to reopen its own to logistics capital. In the final stretch of its administration, the state government launched RioComex, a late attempt to bring Rio back into Brazil’s fierce interstate competition for import flows.
The regime emerges in a politically unstable state, under a governor who was not originally elected to the office and close to the end of the political cycle. The incentive program runs only through 2032, by which time Brazil’s tax reform will have largely completed the transition from the ICMS state VAT system to the new IBS consumption tax. That leaves the initiative looking less like a structural industrial policy and more like a short tactical window.
Still, the rationale is understandable. The package combines ICMS tax deferrals, presumed tax credits of up to 70%, and reductions in the taxable base in an effort to attract trading companies, importers and distribution centers. The ambition is significant: turn Rio’s ports, airports and warehouses into a gateway for goods destined for Brazil’s wealthy Southeast region.
Rio does have real assets — the Port of Rio, Itaguaí, Galeão International Airport and proximity to the industrial and consumer markets of São Paulo and Minas Gerais. But the state lost years in logistics density, administrative predictability and trade infrastructure. Over the past decades, Espírito Santo and Santa Catarina built mature foreign-trade ecosystems with trading houses, logistics operators, customs brokers, warehousing networks and regulatory stability. Paraná, Pernambuco and Ceará also compete aggressively for cargo with their own ports and incentive frameworks.
There is also a less glamorous side to reopening the gates. Brazil already absorbs a flood of low-cost finished goods, often with little technological or industrial value added. Aggressive import regimes can attract logistics investment, but they can also encourage fraud, under-invoicing, aggressive tariff classification, triangular transactions and shell companies.
That does not make RioComex irrelevant. If implemented well, the regime could boost tax collection, generate logistics jobs, improve the use of underutilized infrastructure and reduce Rio’s dependence on oil royalties. But the difference will lie in execution. The state must attract serious operators, not merely tax arbitrage. It will need to offer speed, legal certainty, intelligent enforcement and administrative continuity. It must also avoid turning the incentive into an indirect subsidy for deindustrialization.
The risk is that Rio becomes little more than a fiscal corridor for cheap global merchandise: busy ports, full warehouses, but limited industry, technology or productive spillovers. Brazil’s experience shows that moving cargo is not the same as building a more sophisticated economy.
