Office of Trade Sanctions Implementation (OTSI)

The Office of Trade Sanctions Implementation is the United Kingdom's trade-sanctions implementation and civil-enforcement unit. It launched on 10 October 2024. Its annual review published on 27 August 2026 identifies it as part of the Department for Business, Innovation, Science and Trade (BIST); older guidance describes its former departmental setting as the Department for Business and Trade. OTSI Annual Review 2025-2026, section 2.

Remit and institutional boundary

OTSI's civil-enforcement remit covers specified services and activity outside the UK border. Its powers operate under the Trade, Aircraft and Shipping Sanctions (Civil Enforcement) Regulations 2024, SI 2024/948, with statutory exclusions and the allocation of enforcement functions to HM Revenue and Customs. Licensing, investigation and a finding of breach are different decisions. Regulations 2, 5 and 14.

On 27 April 2026, OTSI assumed sanctions licensing for the export, transfer and making available of goods and technology not subject to strategic export controls, and associated ancillary services. Licensing goods and services also subject to strategic export controls remains with the Export Control Joint Unit (UK). A licence authorises only the named parties, activity, period and conditions specified in it. OTSI licensing guidance.

The Office of Financial Sanctions Implementation (OFSI) handles financial sanctions. HMRC carries out border-related trade-sanctions enforcement and criminal enforcement of trade sanctions. The FCDO Sanctions Directorate belongs to the policy and designation side of the system. OTSI's referral of a suspected breach to another body is not a finding of criminal liability. The annual review's cross-government responsibilities table separates these functions.

Powers and reported activity

Civil tools include information requests, monetary penalties and publication of reports about breaches, subject to the applicable statutory conditions and procedural rights. The regulations permit reports in some cases where no monetary penalty is imposed. They do not turn every allegation or request for information into an established breach. Regulations 5, 11-13 and 17-20.

The first annual review covers 1 April 2025 to 31 March 2026. It records 178 suspected-breach reports or referrals received and 104 enforcement cases closed, including 41 with no breach and no further action and 40 referred to HMRC. These are different activity measures, not a conviction rate or necessarily the same case cohort. The report states that no civil monetary penalties had yet been imposed when published. Annual review, section 3 and Tables A1-A4.

The enforcement collection checked on 26 October 2026 listed OTSI reports and guidance without a later OTSI penalty notice. That observation is limited to the published collection and does not prove that no unpublished investigation, decision or other action exists. Government enforcement collection.

OTSI's creation and expanded remit show investment in implementation capacity. They do not establish that sanctions evasion has fallen. Measuring effects requires dated outcomes and evidence separating enforcement activity from changes in behaviour. Current jurisdiction and an individual transaction's legality depend on the applicable amended regulations and any relevant licence.

Sanctions end-use controls

Sanctions end-use controls must be distinguished from their announcement. SI 2026/443 was made on 20 April 2026 but came into force on 13 May. It inserted Russia regulation 55A, which applies when the Secretary of State has informed a UK person of specified possible diversion to Russia, non-government controlled Ukrainian territory or a person connected with Russia. The goods or related technology must fall within Part 5 and outside the two strategic-control lists identified in the provision. The prohibition is expressly subject to Part 7. These statutory conditions do not create a universal third-country export ban. SI 2026/443, regulations 1 and 15; Russia regulation 55A.

The government's guidance describes a targeted informing and licensing process, while the annual review dates the controls' introduction to April. The operative instrument establishes the May commencement. A particular transaction's licensing route requires separate legal verification: the current Russia regulation 65 wording refers to Chapters 2 to 6 and 6B, whereas regulation 55A sits in Chapter 7. That textual difference is not resolved here by treating guidance as an amendment to legislation. No individual informing notice, licence outcome or measured reduction in diversion is established by these sources. SEUC guidance; Russia regulations 55A and 65; OTSI annual review, section 3.3.
