OECD Gold Supply Chain Guidance Explained
The OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas is the international framework for ensuring that gold (and other minerals) is sourced without financing conflict, human rights abuses or serious crime. Its five-step due diligence process — from management systems through to public reporting — has been adopted into the rules that actually govern the trade, including the LBMA's Responsible Gold Guidance that accredited refineries must follow. Anyone selling into reputable refineries operates, directly or indirectly, under this framework.
What the Guidance Is
Published by the OECD with a dedicated Supplement on Gold, the Guidance answers a hard question: how can businesses buy minerals from difficult regions without funding armed groups or abuses — while still allowing legitimate producers, including artisanal miners, access to world markets? Rather than prohibiting sourcing from high-risk areas, it prescribes due diligence proportionate to risk, so that responsible trade continues while abusive supply chains are cut off.
The Five-Step Framework
- Establish strong management systems. A supply-chain policy, internal responsibility, document and chain-of-custody systems, and grievance mechanisms.
- Identify and assess risk in the supply chain. Know where metal actually comes from — mine, route, intermediaries — and assess against red flags: conflict-affected origins, serious abuses, fraudulently declared origin.
- Design and implement a strategy to respond to risks. Mitigate, suspend or terminate supplier relationships according to the severity of identified risks, with senior management ownership.
- Carry out independent third-party audit of supply chain due diligence at identified points — for gold, principally at the refiner.
- Report annually on supply chain due diligence policies and practices.
How the Guidance Reaches the Real Market
The OECD text itself is soft law — but it has hard edges in practice because it is embedded in the standards that control market access:
- LBMA Responsible Gold Guidance — mandatory for LBMA Good Delivery refineries, audited annually; built directly on the OECD five steps. A refinery that fails loses accreditation — and with it, access to the London market.
- Regulation — the EU Conflict Minerals Regulation and similar regimes impose OECD-aligned due diligence on importers; US issuers face related disclosure rules.
- Hub and exchange rules — major trading centres, including Dubai's DMCC with its responsible sourcing rules for accredited refiners, align their standards to the OECD framework.
- Bank requirements — banks financing gold expect OECD-aligned sourcing controls as part of AML review.
What It Means for Sellers and Facilitators
Practically, anyone selling doré to a reputable refinery will be asked to evidence the OECD-shaped questions: Which mine produced this metal? Who held it between mine and export? Was the origin area conflict-affected? Are the volumes consistent with the source's capacity? This is why origin documentation and chain of custody are not bureaucratic decoration — they are the seller's proof that its metal can lawfully enter the world market. See Responsible Gold Sourcing for the seller-side picture.
Example
A refinery considering a new doré flow from a high-risk region applies the framework: it maps the supply chain to the named mines (Step 2), identifies an intermediary with opaque ownership as a risk, and requires the exporter to source directly from licensed mines with documented custody as a condition of the relationship (Step 3). The arrangement is covered in the refinery's annual independent audit (Step 4) and public reporting (Step 5). The flow proceeds — responsibly — rather than being abandoned, which is precisely the Guidance's intent.
Key Takeaways
- The OECD Guidance is the global framework for sourcing minerals without financing conflict or abuses, with a dedicated Gold Supplement.
- Its five steps: management systems, risk identification, risk response, independent audit, public reporting.
- It binds the real market through the LBMA Responsible Gold Guidance, EU regulation, hub rules like DMCC's, and bank expectations.
- It prescribes due diligence proportionate to risk — enabling responsible sourcing from difficult regions rather than blanket bans.
- For sellers, origin documentation and chain of custody are the practical evidence the framework demands.
Frequently Asked Questions
Is the OECD guidance legally binding?
The text itself is soft law, but it is embedded in binding instruments: LBMA accreditation requirements, the EU Conflict Minerals Regulation, hub rules and bank conditions — so non-conformance excludes you from the legitimate market.
What is a conflict-affected or high-risk area?
An area marked by armed conflict, widespread violence or serious human rights abuses, or weak governance creating those risks. Companies assess this themselves using credible sources; lists and indicators assist but the duty is risk-based.
What is the LBMA Responsible Gold Guidance?
The LBMA's mandatory responsible sourcing programme for Good Delivery gold refineries, implementing the OECD five-step framework with annual independent assurance. It is the main mechanism through which OECD standards govern refined gold.
Does the guidance ban artisanal gold?
No — it explicitly aims to keep legitimate artisanal and small-scale mining connected to world markets, with due diligence and formalisation support, while cutting off flows that finance conflict or abuse.
Who audits compliance with the guidance?
For gold, assurance concentrates at the refinery: independent third-party auditors review refiners' supply chain due diligence annually under programmes such as the LBMA's. Upstream parties are covered through the refiner's checks on its suppliers.
