The RMI provides free, standardized reporting templates to facilitate the transfer of information through the supply chain regarding mineral country of origin and smelters and refiners in use.
The latest versions of the mineral reporting templates (MRTs) are available in the links below, as well as the Smelter Reference Lists corresponding to each of the templates.
Conflict Minerals Reporting Template (CMRT)
Mineral Scope: Tin, Tantalum, Tungsten, Gold (3TG)
CMRT Smelter Reference List
Extended Minerals Reporting Template (EMRT)
Mineral Scope: Cobalt, Copper, Graphite (natural), Lithium, Mica (natural), and Nickel
EMRT Smelter Reference List
Additional Minerals Reporting Template (AMRT)
Mineral Scope is determined by user and includes minerals not covered by the CMRT or EMRT
AMRT Smelter Reference List
News and Updates
The latest versions of CMRT, EMRT and AMRT were released on April 17, 2026.
MRT Training Videos
The RMI has released training videos with topics that are applicable to all 3 MRTs:
- Video 1 - Understanding the purpose and core logic of Mineral Reporting Templates (MRTs) - Link
- Video 2 - How-To Complete MRTs & Common Challenges - Link
These videos are also available in the RMI eLearning Academy.

Frequently Asked Questions
Where do I submit my completed MRTs? Does RMI collect these?
- The RMI does not collect MRTs. MRTs should be provided to your customers and as a good practice measure, and may be posted on your external web site.
What are the differences between the CMRT, EMRT, and AMRT?
- The CMRT and EMRT are limited to a specific scope of minerals, whereas the scope of the AMRT is determined by the user and allows input for up to ten minerals.
- The CMRT and EMRT are intended, in part, to facilitate the exchange of data necessary to meet various regulatory reporting requirements. Specifically, the CMRT supports companies’ compliance with section 1502 of the US Dodd-Frank Act and the EU Conflict Minerals Regulation. The expanded scope of EMRT 2.0 aims to support companies’ reporting requirements under the EU Battery Regulation in addition to certain other prioritized minerals.
- The AMRT was created to enable efficient collection of supply chain data for any prioritized minerals not currently covered by the CMRT or EMRT.
- The CMRT and EMRT were designed to align the IPC-1755 Responsible Sourcing of Minerals Data Exchange Standard (“IPC Standard”), while the AMRT was not designed to fully align with this Standard. It is the intention that over time, additional minerals will be added into the EMRT, as determined by the RMI Minerals Reporting Template team. For additional background on the IPC Standard, refer to pg. 4 of the EMRT Completion Guide.
Why are some of the processors on my suppliers’ lists not found in the MRTs?
- The RMI maintains an up-to-date Smelter Reference list. This list contains all facilities at the Pinch Point supply chain level that have been validated by the RMI to meet the definition of a smelter, refiner or processor at least one mineral in scope of the EMRT. There are several reasons why a supplier may provide a facility not listed in the EMRT. Examples of reasons include: the company does not process one of the minerals in scope of the EMRT, the company is upstream or downstream of a smelter, refiner or processor, the company has yet to be validated as eligible through RMI’s Smelter Disposition Process or the company is no longer in operation and has been removed from the Smelter Reference List. One way to check the status of a SOR that is not on the Smelter Reference list is to become a RMI member, which gives companies access to the RMI’s facility database.
What are resources that companies can use to prioritize minerals and ESG risks?
- The RMI has developed a tool highlighting five key criteria that companies can use to help identify prioritized minerals and ESG risks in their supply chain. RMI members can access the tool here.
- RMI members and non-members can access the Material Insights platform to review ESG risks that are material for various minerals (how prominent are risks for specific minerals with respect to media, government, etc.?) RMI members may join the Emerging Minerals Working group to collaborate with other members in outreach activities to suppliers and to do deep learning of value chains of minerals. Members are also encouraged to regularly attend the RBA policy webinars for updates on compliance and policy developments.
- RMI resources that form the All Minerals Due Diligence Toolbox:
- In addition to Material Insights, the Raw Material Outlook platform highlights salient risks, meaning risks are more likely to occur and that have the greatest severity on impacted people and environment.
- Additional resources for supply chain data:
How can a company handle MRT requests from suppliers/customers that include different minerals than the company's own priority minerals?
- Considering the difference in each company’s business environment as well as risk-based approach and level of influence over the supply chain, it is understood that priority minerals might be differ by company.
- Companies should set reporting expectations for their suppliers/customers for their MRTs. Note that the RMI does not set expectations on reporting for the AMRT, CMRT, or EMRT.
- If the supplier's minerals selection is different from that of requesting companies, it is recommended that the supplier explains to the requesting company how they prioritized the minerals to justify.
- It is recommended that companies hold sufficient discussions in advance with the supplier for the purpose of forming a consensus on whether or not they can respond to minerals they request information about, and when they can respond.
