The 3TGs — Services

Conflict Minerals & Responsible Sourcing

Defensible due diligence. Not checkbox compliance.

Conflict minerals and extended minerals due diligence is no longer optional. SEC disclosure rules, the EU Conflict Minerals Regulation, and customer-driven ESG mandates require rigorous, defensible programs. The 3TGs builds and runs them — from supplier outreach to board-ready reporting.

Conflict Minerals (3TG)

Whether you're responding to customer CMRT requests or building your own due diligence program, The 3TGs brings deep operational expertise — from smelter-level validation to defensible declarations.

What we do
  • CMRT collection, validation, and rollup
  • Smelter identification, deduplication, and RMAP conformance verification
  • Conservative declaration logic — declarations reflect worst-case reality, not supplier optimism
  • SEC Form SD and Conflict Minerals Report preparation support
  • Annual program cycle management: scoping, collection, analysis, reporting
Cobalt · Mica · Beyond 3TG

Extended Minerals

Supply chain due diligence is expanding beyond 3TG. Cobalt, mica, and other minerals face growing scrutiny from regulators and responsible sourcing initiatives.

What we do
  • EMRT deployment and collection
  • Cobalt and mica supply chain mapping
  • Alignment with OECD Due Diligence Guidance
  • Integration of extended minerals into existing 3TG programs
The engine behind your response rates

Supplier Engagement & Training

Your compliance data is only as good as your supplier response rates. Low engagement, bad data, and stalled campaigns cost you audit readiness and market access. The 3TGs fixes that.

Outreach & campaign management
  • Multi-wave campaign design with defined escalation triggers
  • Supplier communication drafting: requests, reminders, escalation notices
  • Response tracking, follow-up sequencing, non-responder management
  • Executive escalation strategies for critical suppliers
  • Supplier segmentation by risk tier, spend, and regulatory exposure
Data validation & quality assurance
  • CMRT/EMRT completeness and accuracy reviews
  • Smelter list validation against RMI conformant smelter database
  • Cross-referencing declarations against known material compositions
  • Flagging inconsistencies and applying conservative declaration logic
  • Data packaging for customer submissions and audit readiness
Supplier training & education
  • Supplier onboarding guides for CMRT, EMRT, and disclosure forms
  • Live and recorded training sessions on regulatory requirements
  • FAQ documentation and step-by-step submission guides
  • Tailored education by supplier tier (Tier 1 vs. sub-tier)
Connecting due diligence to disclosure

ESG & Responsible Sourcing Alignment

Minerals due diligence feeds directly into your broader ESG posture. The 3TGs helps you connect program outputs to investor-facing ESG disclosures and customer sustainability questionnaires.

What we do
  • Program design aligned to OECD five-step framework
  • Mapping due diligence outputs to ESG reporting frameworks (GRI, SASB)
  • Smelter and refiner risk assessment against CAHRAs
  • Policy development for responsible minerals sourcing
  • Supporting customer sustainability questionnaire responses with program data
Beyond compliance — sourcing strategy

Mineral Sourcing Advisory

Responsible sourcing is shifting from a compliance exercise to a strategic differentiator. Companies that can demonstrate clean, traceable mineral supply chains win preferred supplier status, satisfy investor ESG screens, and reduce regulatory exposure before mandates hit.

What we do
  • Supply chain mapping from finished product to smelter/refiner level
  • Risk assessment of sourcing geographies against CAHRAs and sanctions lists
  • Alternative sourcing pathway identification for high-risk minerals
  • Sourcing policy development aligned to customer and investor expectations
  • Ongoing monitoring and reporting on sourcing risk indicators
Every section above connects. Your CMRT program feeds your ESG disclosures. Your supplier outreach drives your response rates. Your sourcing strategy reduces your risk. The 3TGs runs the full loop — so nothing falls through the cracks.
