Sanctions Exposure Scanner

The instinct in sanctions screening is to check names against a list, and that's where many programs stop and many violations begin. The decisive principle — OFAC's fifty-percent rule, with analogues in other regimes — is that an entity owned in the aggregate fifty percent or more by sanctioned parties is itself blocked, even when its own name appears on no list at all. A perfectly ordinary-looking, unlisted company can be off-limits entirely because of who stands behind it. Screening names alone misses exactly these exposures, which are the ones evaders rely on.

That's why ownership tracing is the real work. Sanctioned ownership is routinely buried under layers of holding companies and intermediaries arranged precisely to obscure it, so the only way to know who you're dealing with is to follow the chain to its ultimate beneficial owners and aggregate sanctioned ownership across the whole structure. A clean front company with a blocked parent is still blocked, and "the immediate counterparty looked fine" is not a defense if you never looked further up.

It's also a multi-regime problem. OFAC, the EU, the UN and the UK maintain overlapping but non-identical lists, and you are bound by every regime with jurisdiction over your transaction — which is frequently more than one at once. A party clear under one regime may be sanctioned under another, so comprehensive screening means checking all the applicable lists against current data, not picking the one that's convenient. Red flags — opaque structures, reluctance to disclose owners, high-risk routing — add a further duty to investigate before proceeding.

And the stakes make all of this mandatory rather than optional: sanctions violations are often strict-liability, so intent isn't required, and the penalties are severe for organizations and individuals alike. That reality is why a tool like this can only ever teach the logic — the fifty-percent rule, ownership tracing, multi-regime screening, red flags — and never stand in for an actual screening run against official, current lists with proper tools and compliance counsel. Use it to build the right instincts and triage, then check product and destination controls in the Export Control Checker, fold the exposure into your China risk picture — and, for any real transaction, screen properly and consult your compliance function.
