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 Licensing
May 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 cover
The 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:
the import into the UK of oil products falling within commodity code 2710, which have been processed in a third country from oil and oil products originating in Russia;
the import into the UK of uranium consigned from, or originating in, Russia;
the acquisition (directly or indirectly) of uranium originating in, or located in, Russia;
the supply or delivery (directly or indirectly) of uranium from a place in Russia to a third country;
the supply or delivery (directly or indirectly, including ship-to-ship transfers) of LNG from a place in Russia to a third country or from one third country to another third country, where such LNG falls within commodity code 2711 11 00 and originates in, or is consigned from, Russia;
the provision (directly or indirectly) of brokering services, financial services and funds relating to all of the above activities; and
the provision (directly or indirectly) of technical assistance relating to the above activities concerning third country processed oil products and uranium.
The new prohibitions also include restrictions concerning detained transport assets and services relating to specified ships (as may be determined by the Secretary of State).
Refined products ban
The prohibitions on import of third country refined products made using Russian oil are effective as of today (20 May 2026).
Tank heel: Tank heel residues from prior Russian oil use do not make subsequent non‑Russian crude oil or oil products shipments prohibited for import into the UK.
Oil products produced using crude oil that originates in a third country and flows through Russian pipelines: The ban is not contravened where a non-Russian oil product is produced in a third country using non-Russian crude oil and has only transited through.
Co-mingling: Notwithstanding the above two points, the prohibitions apply to co-mingled products, whether arising from (i) co-mingled crude oil that is subsequently refined, or (ii) co-mingling of refined products.
Bunkering: Vessels entering UK ports and aircraft flying to the UK do not need to verify the origin of onboard fuel, provided that the fuel is used solely for their operation during the voyage or flight.
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:
Sanctioned processed oil products: the GTL facilitates the movement of diesel and jet fuel made using Russian oil (which would otherwise be captured by new UK sanctions prohibitions on Russian oil products). The GTL is currently of indefinite duration, though is subject to periodic review and may be varied, revoked or suspended at any time.
Maritime transportation of LNG: the GTL permits the maritime transport of LNG connected to specified Russian projects (specifically, to shipments from Sakhalin‑2 and Yamal LNG terminals) to destinations outside the UK, as well as associated financial and brokering services. The GTL applies on a time‑limited basis until 1 January 2027 and applies to contracts with a duration of one year or less.
To whom do the licences apply
The 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:
any UK person (and, where relevant, persons within UK territorial jurisdiction) may rely on the GTLs if their activity falls squarely within the permitted acts and all conditions of the specific licence are met (including record‑keeping and, importantly, any notification/registration requirements expressed in the licence);
counterparties and intermediaries (for example, shipowners, charterers, insurers, port service providers, commodity traders, storage operators and financial institutions) can also rely on the GTLs, again only to the extent their role is expressly covered and they adhere to licence conditions. For parties outside UK jurisdiction, it is important to confirm whether and how UK sanctions touchpoints arise (for example, via a UK territorial nexus, or involvement of UK persons such as UK insurers or UK‑flagged vessels).
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:
Activity-specific permissions with clear boundaries: each GTL defines exactly what is permitted (i.e. the types of processed oil products covered or the routes/destinations and associated services allowed). Users should map their transaction steps (including procurement, blending/processing, storage, loading, carriage, discharge, and services such as financing and insurance) against the licence wording.
Conditions, attestations and records: GTLs impose conditions for use (such as maintaining specified records, obtaining/retaining attestations or certificates, and producing documents to authorities on request).
Transitional and expiry dates: the LNG GTL is explicitly time‑limited (until 1 January 2027) and includes transitional treatment for certain pre‑existing contracts. Users should diarise both the contract cut‑off and the licence expiry date, and avoid voyages that would complete outside the validity window unless/until the licence is renewed.
Interface with other prohibitions: relying on a GTL does not waive other sanctions restrictions (e.g. asset freezes, price cap compliance for oil products, trade restrictions on non-covered products and ancillary services prohibitions outside the scope of the GTLs). Parties should continue to run full counterparty and product due diligence, and ensure price‑cap attestations and record‑keeping are in place where required.
Registration/notification (if required by the licence): the LNG GTL requires users to inform the Department for Business and Trade within 30 calendar days before carrying out activities covered by the licence.
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.
Key takeaways / how to stay ahead of the curve
Build licence conditions into contracts and operations: parties should ensure contracts/agreements are up-to-date to take account of the latest restrictions and applicable GTL cut‑off dates in operational plans.
Monitor renewals and changes: GTLs and the underlying restrictions can be amended, suspended, or revoked. Parties relying on the GTLs or exceptions should track updates and flag expiry dates and wind-down periods well in advance in order to mitigate compliance risk.
Keep the broader sanctions picture in view: a GTL is not a blanket waiver. Parties should continue to assess UK nexus and separate/parallel regimes (including UK sanctions against jurisdictions other than Russia, as well as the EU and US sanctions regimes) for multi‑jurisdictional voyages and trades. If the transaction touches EU/US persons or the US financial system, these implications should be considered separately.
