SCS is recognized by the Responsible Minerals Initiative (RMI) as an approved auditing firm for the Responsible Minerals Assurance Process (RMAP). Verification to the RMAP provides assurance to companies that the smelters and refiners within their supply chain employ responsible sourcing practices and management systems. RMAP requires a third-party audit against the RMAP Protocols which are currently the highest level of due diligence (in accordance to the OECD*) for determining that refiners and smelters are not sourcing conflict minerals for their production of tantalum, tin, cobalt, tungsten and gold (3TG).

SCS Global Services is a third-party audit service provider approved to conduct Responsible Mineral Assurance Protocol (RMAP) assessments for Responsible Minerals Initiative (RMI) member smelters and refiners.  Auditors assess an auditee’s management processes to meet responsible mineral procurement practices and align with requirements set by OECD Due Diligence Guidance, the Regulation (EU) 2017/821 of the European Parliament and the U.S. Dodd-Frank Wall Street Reform and Consumer Protection Act.

What types of materials or services qualify for this RMAP verification?

The RMAP audit focuses on smelters and refiners, the “pinch point” in the metal supply chain between upstream (i.e. mine) and downstream (i.e. manufacturers) actors. Current metals in scope include Tin, Tantalum, Tungsten, Gold, and Cobalt.

Once we are found conformant, how many years does the conformance verification last?

Conformance determination is valid for 1 year; special circumstances must be met to qualify for a 3-year conformance determination.

How long does and RMAP  audit take?

Audit length is determined by RMIs RMAP program manager, but generally depends on the smelter/refiner’s sourcing practices, size, and complexity of operations.

Are RMAP audits onsite or virtual?

RMAP audits are conducted in-person; virtual audits are allowed under special circumstances and must be approved by the RMI.
