For years, the Jones Act has effectively cut off Puerto Rico’s access to mainland propane. The reason is simple: there are no Jones Act-compliant oceangoing LPG (liquefied petroleum gas) tankers capable of transporting it. The only possible uncertainty was whether Puerto Rico wanted American propane in the first place. Thanks to the March 2026 Jones Act waiver, that’s now settled.
Since the waiver took effect, Puerto Rico has imported roughly 809,000 barrels of mainland propane. That’s 4,792 percent more—nearly 49 times—the average annual volume shipped from the mainland during 2004–2025. Put another way, it’s more than twice the amount of mainland propane shipped to Puerto Rico during the previous twenty-two years combined.
