OFAC added nine Cuban officials to the SDN list on Monday 18 May, the same action that issued GL 134C, with one of the nine based in Cienfuegos, the south-central Cuban port that hosts the island's primary refinery 1. Paragraph (b)(1) of the licence excludes Cuba outright, carrying forward the carve-out that already stood when GL 134B lapsed on 16 May .
In practice that creates a Cuba-tainted cargo class. Any pre-17-April Russian barrel that touched a Cuban intermediary between loading and delivery loses 134C cover entirely. A trader who priced a Primorsk loading as fully covered now has to re-screen the whole voyage chain, because one Cuban counterparty voids the waiver for the entire cargo, not a fraction of it.
There is no pro-rata haircut to hedge against a Cuban touch: a cargo is either clean or it is uninsurable under the licence, so the diligence burden sits on proving a negative across every ship-to-ship transfer and every chartering counterparty. The sanctions policy belongs to the Russia file; the cargo-classification cost it triggers lands squarely on the desks completing those cargoes.
