Rotterdam arrest exposes sanctions loopholes

Dutch customs officers went through dozens of containers on a vessel travelling its usual Rotterdam-St Petersburg route. They found windscreens, car doors, motor oil and air filtration systems: ordinary parts with a military afterlife, all sanctioned, with labels removed and replaced to disguise where they had come from. The captain was arrested on the spot. Raids followed at addresses in Rotterdam and Amsterdam (Duane Morris).

The goods were not exotic. They were the consumables that keep trucks, industrial fleets and military vehicles moving, and that European manufacturers sold freely before Russia's war forced the EU to close the route. The EU has banned a broad range of exports to Russia, across hundreds of product categories. Writing the ban was the easier part. Stopping the goods is the harder one.

Three countries carry the load

EU sanctions enforcement still works largely through national systems. Each member state runs its own customs checks. There is no shared EU database of flagged shipments, no common inspection standard and no central enforcement body for goods.

That leaves enforcement where national capacity, political will and geography happen to align. Poland generates 56% of all Rapid Information Form alerts, the EU mechanism used to flag suspicious exports. That is more than the other 26 member states combined. The Netherlands and Finland have built specialised teams to run criminal investigations. Most others are well behind.

Ireland is in that second group. It has conducted zero sanctions prosecutions since 2022. When the EU required every member state to criminalise sanctions violations by May 2025, only Estonia and Finland met the deadline. The Commission has opened infringement proceedings against 18 of 27 member states, including Germany, France and Spain.

The detour that beats customs

The Rotterdam seizure dealt with the bluntest kind of evasion: relabelled boxes on a direct route to Russia. The more difficult problem is the trade that moves legally before it stops being legal in practice.

Since 2022, EU exports of sanctioned goods to several Central Asian countries have risen sharply. Kyrgyzstan, Armenia and Kazakhstan are all members of the Eurasian Economic Union, a customs union with Russia, which means goods can move freely across borders once they clear entry. An Oxford study found that the spike in sanctioned-good exports to these countries began within days of sanctions taking effect. The timing points strongly to circumvention, though the absolute volumes are still contested and some large percentage increases began from very small bases.

The EU activated its anti-circumvention tool against Kyrgyzstan in April 2026 for the first time. The pattern had been visible for four years.

The law as loophole

Ireland's own problem sits in plain sight. Aughinish Alumina, Europe's largest alumina refinery, is owned by the Russian metals group Rusal. Alumina, the raw material used to make aluminium, moves from Aughinish to Rusal smelters, and an investigation traced the material onward to manufacturers of Iskander ballistic missiles and Shahed drones, both used against Ukraine.

All of it is legal. Alumina was deliberately excluded from EU sanctions because European smelters in France and Sweden depend on Aughinish's output. The Taoiseach has called sanctions on the plant "self-defeating".

The Rotterdam captain now faces prosecution. Aughinish's owners do not. The difference is not moral distance from the war. It is that Brussels wrote a rule for one flow of goods and an exemption for the other.

The 21st sanctions package, expected in late June, is not expected to change that. The Commission has already indicated that Aughinish will remain exempt. A proposed full ban on European shipping and insurance services for Russian oil tankers is stalled by Greece, Cyprus and Malta, whose shipping industries depend on the trade. When European commercial interests are large enough, enforcement tends to stop exactly where the law tells it to stop.
