The EU and the G7 set a $60/bbl price cap on seaborne Russian crude. SNSUC's compliance rule is firm: any transshipment tied to Urals must clear below that line, and it must be self-evidenced with three documents.

The three documents are: (1) the invoice, stating unit price and total; (2) the load-port paperwork — bill of lading or waybill — proving the cargo actually lifted from a Russian port; and (3) freight and insurance evidence, proving the full logistics cost is transparent. Unit price, quantity and vessel name across the three must interlock; any mismatch breaks the compliance chain.

On sanctions screening, Iran is SNSUC's sole auto-reject origin. Iraq has been explicitly exempt since October 2026 and is not on the auto-reject list. In practice, SOMO Iraqi crude can run through SNSUC's named-buyer process normally, but if the origin field reads Iran, the system blocks it outright and never routes to manual review.
