UK Closes Down the ‘Refining Loophole’ While Mitigating Energy Market Strain via Targeted Licensing

UK Closes Down the ‘Refining Loophole’ While Mitigating Energy Market Strain via Targeted LicensingMay 20, 2026 Effective as of today (20 May 2026), the UK implemented a new package of sanctions against Russia, targeting (among other things) third country processed oil products made from Russian crude, Russian uranium, Russian liquified natural gas (LNG). In parallel, the UK Office of Trade Sanctions Implementation (OTSI) has issued two new targeted General Trade Licences (GTLs), covering: (i) certain categories of the newly-sanctioned processed oil products; and (ii) maritime transportation of LNG. In this briefing, we summarise the new prohibitions, as well as what each licence seeks to achieve and the actions businesses should take as a result. Similar to the import ban recently introduced by the EU in relation to petroleum products made from Russian oil, the new UK prohibitions serve to ‘close the loophole’ which allowed Russia to benefit from sales of crude oil which ultimately ends up on the UK market after transformation in third countries. Meanwhile, the newly-issued GTLs have the effect of relaxing (albeit in a temporary and limited fashion) certain UK sanctions against Russia. What the new prohibitions coverThe new prohibitions update the Russia (Sanctions) (EU Exit) Regulations 2019 (UK Russia Regulations) to include restrictions (subject to certain exceptions, including wind-down periods) on:
Refined products banThe prohibitions on import of third country refined products made using Russian oil are effective as of today (20 May 2026). The UK Government has published supplementary guidance on the application of these measures (please see here: Guidance on third country processed oil product measures) (Guidance), with the following points being noteworthy:
What the new licences coverThe GTL covering sanctioned processed oil products authorizes certain activity involving third country products refined using Russian oil.The GLT covering specified maritime transportation of LNG authorises certain activity linked to designated Russian projects (Sakhalin‑2 and Yamal LNG) under strict conditions and for a limited period. Both licences are framed narrowly and are subject to strict compliance with detailed terms, conditions and expiry provisions set out in the licence instruments themselves:
To whom do the licences applyThe GTLs are “general” permissions available to any person who meets the scope and conditions of the licence; no individual licence is needed provided all terms set out within the GTLs are satisfied. In practice, this means:
How the licences are expected to work in practice
Although each GTL sets its own terms and should be considered independently, the following are key operational features:
Commentary
The result is something of a mixed picture from a policy perspective. On the one hand, the new prohibitions put even more pressure on Russia and bring the UK more in line with the position adopted by the EU. On the other hand, the issuance of the GTLs contrasts with the position taken by the UK Government just a few months ago, and is a move more in line with the position recently adopted by the US (which has extended its existing sanctions waiver on Russian oil in a further attempt to stabilise rising fuel costs).
At this stage, it is reasonable to interpret the issuance of the GTLs as a temporary measure to achieve a strategic objective rather than an overall shift in wider UK sanctions policy - indeed, the UK Government has indicated that the aim of the GTLs is to protect critical supply chains and maintain market stability in the wake of continued disruption due to the blockade of the Strait of Hormuz. Accordingly, the prevailing trend in UK sanctions policy continues to be one of tightening restrictions and increasing the focus on enforcement and anti-circumvention measures. The new UK restrictions will have impacts across supply chains - businesses should ensure their internal due diligence and compliance mechanisms are updated accordingly.
