Difference Between CMRT vs EMRT vs AMRT

As the global supply chain becomes more complex and regulatory pressure on responsible sourcing intensifies, companies must track the origins of minerals used in their products. Whether it’s to comply with mandatory regulations like the U.S. Dodd-Frank Act or to meet voluntary ESG targets, standardized tools such as CMRT, EMRT, and AMRT are essential for due diligence.

Let's explore the key differences between these three reporting templates—Conflict Minerals Reporting Template (CMRT), Extended Minerals Reporting Template (EMRT), and Additional Minerals Reporting Template (AMRT)—so your compliance efforts are always one step ahead.

What is the CMRT?

The Conflict Minerals Reporting Template (CMRT) is the original standardized tool created by the Responsible Minerals Initiative (RMI) to support supply chain due diligence on the sourcing of 3TG minerals:

• Tin
• Tantalum
• Tungsten
• Gold

These minerals are often linked to financing armed conflict and human rights abuses in the Democratic Republic of the Congo (DRC) and adjoining countries. Companies subject to Section 1502 of the U.S. Dodd-Frank Act or the EU Conflict Minerals Regulation use CMRT to gather data from suppliers, identify smelters/refiners, and determine country of origin.

Key Details of CMRT:

• Latest Version: CMRT 6.5 (Released April 25, 2025)
• Regulatory Use: Mandatory for SEC filers and EU importers of 3TG
• Structure: Supplier engagement, smelter list, origin countries, company policy declarations

What is the EMRT?

The Extended Minerals Reporting Template (EMRT) was introduced to expand mineral due diligence efforts beyond 3TG. It covers high-risk extended minerals used in modern electronics, batteries, and industrial manufacturing:

• Cobalt
• Mica
• Copper (added in EMRT 2.0)
• Lithium (added in EMRT 2.0)
• Nickel (added in EMRT 2.0)
• Natural Graphite (added in EMRT 2.0)

EMRT aligns with the OECD Due Diligence Guidance and supports voluntary compliance in light of evolving regulatory expectations—particularly the EU Battery Regulation.

Key Details of EMRT :

• Latest Version: EMRT 2.0 (Released April 25, 2025)
• Regulatory Use: Voluntary, ESG-driven, aligns with EU Battery and Green Deal targets
• Structure: Supplier declarations, smelter/refiner identification, mine-level origin (optional)

What is the AMRT?

The Additional Minerals Reporting Template (AMRT)—previously the Pilot Reporting Template (PRT)—is RMI’s most flexible due diligence tool. It enables companies to track any 1–10 minerals of concern that aren’t already covered under CMRT or EMRT.

Companies use AMRT to get ahead of potential regulatory risks and ESG scrutiny involving materials such as:

• Rare earth elements
• Critical raw materials flagged by the EU or U.S.
• Sector-specific minerals under NGO or customer pressure

Key Details of AMRT:

• Latest Version: AMRT 1.2 (Released October 4, 2024)
• Regulatory Use: Voluntary; insight-driven risk assessment
• Structure: Fully customizable; user defines which minerals to report and data to collect

Why These Templates Matter

Global supply chains increasingly face scrutiny from regulators, investors, and conscious consumers. Whether mandated (as with 3TG under CMRT) or voluntary (as with cobalt, mica, and additional minerals), transparency tools like these templates are crucial.

Using CMRT, EMRT, and AMRT together ensures:

• Better supplier engagement and risk identification
• Streamlined compliance documentation
• Trust-building with stakeholders and customers
• Readiness for incoming regulation
