On 9 March 2026, the LME issued a combined consultation and discussion paper that considers several possible enhancements to its physical market operations – and, in particular, its warehousing network.
The enhancements set out in the LME Physical Markets Consultation and Discussion Paper (the “Consultation and Discussion Paper”) were developed with the broad aims of improving operational transparency and efficiency, supporting fair access and competition between warehouse operators, and enhancing the robustness of physical delivery mechanisms.
Following careful consideration of the responses received, the LME has decided to implement all proposals set out in the consultation section of the Consultation and Discussion Paper. The new requirements will come into effect at varying times, with most of the new requirements coming into force in the future, further information on the implementation dates can be found in the LME Physical Markets Reform 2026 Feedback Analysis and Decision Notice. Please note that the LME Rulebook, Warehouse Agreement and LME Policy on the Approval and Operations of Warehouses will also be amended to reflect the new requirements.
Certain measures are subject to separate implementation timelines, including the new copper Certificate of Analysis (“CoA”) requirements, which will take effect on 1 January 2028, and the indelible marking requirements, which will follow the extended transition timetable set out in Section 3.5 of [can we insert the notice number?] the relevant notice.
In addition, on 31 July 2026 the LME is simultaneously publishing the Further Consultation on Physical Markets Enhancements (“Further Consultation”) which seeks additional feedback on two proposals previously outlined in the discussion section of the Consultation and Discussion Paper.

It also includes a package of proposed amendments to the LME's brand listing requirements, the purpose of the proposal is to streamline the listing process while maintaining the quality and integrity of LME-listed brands.
