This updated version plays a crucial role in enhancing supply chain transparency and improving the quality of conflict minerals data reported globally.
Overview of CMRT 6.6 Release
The first CMRT update of 2026, version 6.6, marks the 30th CMRT release and the 10th release within version 6. It reflects RMI’s ongoing efforts to refine and modernize conflict minerals reporting.

Key Updates in CMRT 6.6 for Conflict Minerals Compliance
1. Enhanced Product Identification
One of the most significant updates in CMRT 6.6 is the improvement in the product list. The template now includes Requester Product Number and Requester Product Name fields.
These additions help downstream customers better understand CMRT declarations related to specific products and reduce the need for repeated follow-ups with suppliers.
2. Alignment with IPC-1755
CMRT 6.6 introduces functional improvements aligned with IPC-1755, an industry standard for material declaration and reporting.
This alignment enhances compatibility for organizations working within broader environmental and material compliance frameworks.
3. Updated ISO Country and Region Codes
The template now includes updated ISO short names for countries, states, and provinces.
This update helps reduce data entry discrepancies, improves accuracy in analysis and risk management, and ensures greater global consistency in reporting.
4. Updated Smelter Reference Lists
As with every CMRT update, version 6.6 includes refreshed smelter and standard smelter reference lists.
These updates reflect newly identified smelters and refiners, improving data accuracy and strengthening due diligence assessments.
Benefits of CMRT 6.6 for Companies
