Compliance precedes the trade.
Every consignment is risk-tiered against the OECD Due Diligence Guidance framework: Tier 1 for low-risk jurisdictions, Tier 2 for medium risk, Tier 3 for conflict-affected and high-risk areas. Tier 2 and Tier 3 origins require an independent OECD Step-5 assurance report issued within ninety days of shipment. Cargoes without it are refused, not renegotiated. Screening against UN, EU, OFAC, and UAE sanctions lists is a precondition, not a line item.
