Divergence between allies: what the US lists that the EU does not

The assumption worth testing

Coverage of sanctions tends to describe “the West” acting together. Against a specific hull, that is often not what the data shows.

The three main lists in this database overlap considerably less than the rhetoric implies. A substantial share of vessels are listed by exactly one authority. The statistics page carries the live numbers, including how many hulls each authority lists alone, and the median gap in days between one authority acting and another following on the same hull.

Why the gaps exist

Different legal instruments. The US blocks property interests; the EU bans port access and services; the UK specifies ships for shipping sanctions. Each has its own evidentiary standard and its own internal process, and they are not designed to produce identical outputs.

Different policy scope. The US programs cover Iran, Venezuela and North Korea at scale alongside Russia. The EU and UK vessel lists are dominated by Russia. A large part of the apparent US “lead” in vessel numbers is simply the other three trades.

Different decision processes. An EU listing requires agreement among member states and arrives in periodic packages. A US designation can be announced on any working day. That difference alone produces clustering in EU dates and a steadier drip in US ones, which is visible in the listing velocity chart.

Different consequences of being wrong. Each authority faces its own litigation risk from designating a vessel, and each weighs that differently.

What the gap means in practice

For a specific tanker, the practical question is which doors are closed.

A hull listed by the EU alone cannot enter EU ports or receive EU services. It can load in a third country, carry a cargo to a buyer outside the EU, and use insurance and classification from providers outside the EU, without breaching that regulation.

A hull listed by OFAC alone faces blocked property status and, under several programs, secondary-sanctions exposure that makes banks and insurers well outside the United States cautious. That reach is broader in practice than the port ban, even though the formal jurisdiction is narrower.

A hull listed by all three has few routes left inside the G7-linked economy, and the remaining ones run through counterparties, insurers and ports that accept the risk.

Delistings diverge too

Removal is not coordinated either. When one authority delists a vessel — after a scrapping, a change of ownership, or a policy shift — the other listings stand until each authority acts separately.

This is why every vessel page here records status per authority rather than as a single label, and why a hull can show as “listed by some authorities, removed by others”. Reporting that describes such a ship as simply “delisted” is wrong in two of the three jurisdictions.

What to do with this

If you are assessing exposure, the only useful question is jurisdiction-specific: is this hull listed by the authority whose law binds me, today? A yes elsewhere is a risk indicator and a reason to look harder, not an answer.

If you are writing about a vessel, name the authority. “Sanctioned” without an actor is the single most common error in this subject, and it is the one that most often turns out to be wrong.

The directory filters by authority, so the single-authority populations can be inspected directly, and each vessel page states in words which of the three authorities do not list the hull.
