A European commodity trading house built on transparency, compliance, and long-term commercial relationships.
SEI Petroleum was established to fill a gap in the European commodity trading landscape: a compliance-first, documentation-driven intermediary that could bridge producers, refineries, and end-users without compromising on regulatory integrity.
Operating from Romania, Poland, and the United Kingdom, SEI Petroleum benefits from EU and UK legal and regulatory frameworks, access to major European logistics corridors, and established relationships across supply regions in Europe, the Middle East, Central Asia, and beyond. Our Romanian entity — Lagartha S.R.L. — holds the primary trading and commercial operations, while our Polish and UK offices extend our reach across European and global markets.
Every trade we facilitate begins with compliance: KYC-screened counterparties, sanctions-checked jurisdictions, and a complete documentation trail from nomination to delivery. We do not cut corners on regulatory procedures — and our clients value this consistency.
"Trusted Energy. Global Reach."
We do not engage in transactions that compromise regulatory standards, ethical conduct, or counterparty safety. Integrity is the non-negotiable foundation of every trade we facilitate.
We provide complete documentation, clear pricing structures, and open communication at every stage of the trade lifecycle. Our clients always know exactly where their cargo stands.
We deliver what we commit to — on time, on specification, and within the agreed commercial terms. Consistent execution is what turns a first transaction into a long-term partnership.
All trading contracts, invoices, and letters of credit are issued under Lagartha S.R.L.
