The London Bullion Market Association sets the due-diligence and disclosure rules for the 66 refiners on its gold Good Delivery List. Its Responsible Gold Guidance is mandatory for every one of them, Disclosure Guidance v3 makes transparency comply-or-explain from 2026, and a v10 revision entered public consultation in June 2026.
Visit lbma.org.ukA refiner that wants its bars accepted in the London market needs a place on the LBMA’s Good Delivery List, and that place comes with rules attached: Responsible Sourcing compliance is a condition of accreditation, alongside at least five years of operation, ten tonnes a year of refining and GBP 15 million in net worth. The gold list held 66 refiners when this hub checked it in July 2026.
The centre of the system is the Responsible Gold Guidance, an OECD five-step-aligned due-diligence standard, mandatory for all gold Good Delivery refiners. Version 9, published in November 2021, applies from financial year 2022. A v10 public consultation opened at the June 2026 LBMA summit: it is set to integrate the ASM Toolkit, update the recycled-gold definition and extend disclosures.
Around the standard sit the transparency and integrity layers: Disclosure Guidance v3, published in December 2025 and effective 1 January 2026, two years ahead of schedule, and the Gold Bar Integrity programme run with the World Gold Council. Since March 2022 an ASM Initiative and its Toolkit (now v6) give refiners a progressive-improvement route to artisanal supply, which the LBMA puts at up to 20% of mined gold but under 1% of Good Delivery refiner throughput.
Responsible Gold Guidance v9 is published in November; it applies from financial year 2022.
The ASM Initiative launches in March, opening a pathway for artisanal gold into Good Delivery refining.
Shenzhen Yuexin becomes the most recent gold addition to the Good Delivery List (effective 19 December, per the GDL Newsletter of April 2025).
The GBI database goes live on aXedras in January. The European Commission’s Conflict Minerals Regulation assessment scores the RGG 89% on Section A and full on B and C: "partially aligned". An Incident Review opens on Istanbul Gold Refinery in October. Disclosure Guidance v3 is published in December, two years early.
DG3 and the Good Delivery Rules 2026 take effect on 1 January. An Incident Review opens on Heraeus in February. Voluntary country-of-origin reporting starts in April. The June summit launches the RGG v10 consultation and publishes "Supporting Pathways for Responsible ASM".
The system is active and tightening: DG3 arrived two years ahead of its original schedule, and the Rules 2026 edition took effect on 1 January 2026. On the EU side, the 2025 Conflict Minerals Regulation assessment left the RGG "partially aligned" (89% on Section A, full on B and C), with reapplication anticipated by summer 2026.
Two Incident Review Processes are open as of July 2026: Istanbul Gold Refinery (invoked October 2025 after Turkish authorities detained 21 people, including the main shareholder, over alleged export-incentive fraud) and Heraeus Precious Metals (invoked February 2026 after reported suspected fraud in the Hanau recycling business, with EUR 457.7m in provisions per Heraeus). Both remain Good Delivery refiners while the reviews run; neither has a public resolution.
Two counting notes this hub tracks: the gold Good Delivery List holds 66 refiners, while the LBMA’s "100+" figure counts gold and silver refiners together (reconciliation unresolved); and the claim that 100% of Good Delivery refiners were using the GBI database by the start of 2026 is the LBMA’s own, its scope being the upload of assurance deliverables.
