The institutional framework
ZED Mariel operates under the Cuban Decreto-Ley that created it in 2013 and is administered in connection with the Ministry of Foreign Trade and Investment (MINCEX). Rather than negotiating across scattered agencies, investors deal with a zone framework designed to consolidate the process.
The zone's legal basis is what distinguishes it from ordinary economic activity elsewhere in Cuba. Applicants are evaluated and approved through the zone's own administration, which sets terms within the framework established by Cuban law.
The single-window office
A defining feature is the Ventanilla Unica, or single window: a one-stop office meant to centralise the permits, registrations, and approvals an investor needs. The single-window concept is common to special economic zones globally and is intended to reduce the administrative friction of establishing a business.
Beyond paperwork, the zone pairs this with proximity to the deepwater container terminal and the road and rail corridor to Havana, so an approved operation has both a maritime outlet and inland connectivity.
The sanctions reality
Any assessment of Mariel must account for US sanctions administered by OFAC. These constrain which foreign companies — particularly those with US ties or reliant on the US financial system — can invest in or ship through Cuba, and they affect banking, insurance, and vessel arrangements.
This page describes the zone's structure in general terms only. It does not state specific tax rates, incentives, land terms, or eligibility criteria, and it is not legal, financial, or investment advice. Prospective investors should consult qualified counsel and the relevant authorities directly.
Doing the homework
Because the zone's terms and the sanctions landscape both change, due diligence is continuous rather than a one-time checklist. Verifying the current legal framework, confirming that partners and financing are compliant, and understanding logistics realities on the ground all matter before commitment.
The practical value proposition of ZED Mariel — a modern deepwater terminal, an organised zone administration, a single-window office, and inland links to Havana — is genuine, but it operates inside real constraints. Treating this page as a factual orientation rather than a source of specific figures is the right posture, and any decision should rest on authoritative, up-to-date guidance from qualified professionals and official Cuban sources.
