Quick answer
Critical minerals due diligence software covers four jobs: mapping the supply chain, collecting supplier evidence, screening risk, and reporting to regulators and customers. This page compares the main options against each of them.
Who this is for: Procurement, compliance and sustainability teams in mining, metals and manufacturing choosing a due diligence platform.
See supply chain due diligence →Most tools sold as critical minerals due diligence software were built for general supplier risk and pointed at mining later, once a few customers asked for it. The moment you get into 3TG smelters, current RMI lists, and the overlap between IRMA, Copper Mark, and CMSI, the generic option starts asking you to enter the same evidence for the third time.
The work multiplies through requesters rather than rules. The OECD Guidance sets the floor, then each customer builds its own version on top, in its own format, on its own deadline. Regulation is the smaller half of the inbox.
Comparing tools in this category is difficult because they are not competing at the same thing. This guide sets out the four jobs the work breaks into, scores eight tools against all four on the same basis, from broad supply-chain risk platforms to specialist conflict minerals software, and ends with a test you can run on one real supplier in a week.
TL;DR
Due diligence in critical minerals is four jobs, not one: mapping supplier risk, filing conflict minerals reports on 3TG, proving framework readiness, and answering the requests your own customers send you.
Seven of the eight tools below cover one or two of those four in depth. The gaps between them are where the manual re-entry happens.
Exiger, Prewave, and IntegrityNext are built around monitoring large, mixed supplier bases across many industries. Assent, Source Intelligence, and iPoint are built around 3TG and product compliance in manufacturing.
beSirius is the only one on the list built for mining, metals, and critical minerals specifically, and the only one covering all four jobs from a single Twin per company.
On any shortlist, the deciding factor is whether evidence entered once carries across every framework and every inbound request, or gets re-keyed each time.
What critical minerals due diligence software has to do
Four jobs hide inside this category, and most vendors are built around one or two of them.
1.Supplier and counterparty risk
Mapping who you buy from, and who they buy from, against the OECD five-step framework, then flagging risk by country, commodity, and smelter.
2.Conflict minerals reporting on 3TG
Collecting and validating CMRT and EMRT data, and checking smelters against the current RMI conformant smelter list rather than the version downloaded in March. This is the job most conflict minerals software was built around, and the CMRT guide walks through it in full.
3.Framework and certification readiness
Showing where you stand against IRMA, Copper Mark, CMSI, GBA, ResponsibleSteel, and the EU Battery Regulation.
4.Answering what your customers send you
The KYC forms, questionnaires, and rating submissions such as EcoVadis and CDP that arrive in your inbox and hold up a contract until someone fills them in.
The friction sits in the gaps between these four rather than inside any one of them, because each job usually lives in its own system, so the same audit report gets uploaded four times by four different people.
When teams start looking for this
Shortlists in this industry tend to start at one of four moments, and each one changes what matters in the comparison.
- A customer questionnaire takes a week to answer and a contract is waiting behind it.
- An audit asks for evidence that exists somewhere but cannot be produced in the format the auditor wants.
- Supplier count grows past the point where one person can hold the picture in their head.
- A second framework arrives and the same criteria have to be answered again under a different name.
The first and fourth are the ones that repeat. A tool that solves the audit in front of you and leaves the next request untouched buys a quarter, not a year.
How the eight tools were compared
Each tool is assessed against the four jobs above, using the same three-level scale, based on public product documentation as of July 2026.
Core. The job the product was designed around, with the industry-specific detail the work needs.
Partial. Covered, but either as a secondary module or without minerals-specific depth such as smelter validation.
Outside scope. Not what the product is for.
Coverage matrix
Read the matrix by row for what a tool will do, and by column for how many systems a full programme currently takes. Most teams in this industry are running two or three of these at once, which is why the same evidence gets entered repeatedly.

The 8 tools compared: critical minerals due diligence and conflict minerals software
beSirius
beSirius is AI-native sustainability and due-diligence data infrastructure built for mining, metals, and critical minerals value chains. Rather than another form to fill in, it builds a Twin, a structured profile of a company's policies, certifications, audits, and supplier data. Insight runs that Twin against any framework and returns a gap analysis with evidence linked to each requirement, and Answer fills any questionnaire, KYC form, or rating submission from the same source.
Coverage. All four jobs, from one Twin per company.
- Frameworks include IRMA, Copper Mark, CMSI, RMI and RBA, GBA, ResponsibleSteel, CDP, and EcoVadis.
- Cross-framework equivalency is built in, so an IRMA result already satisfies the overlapping RMI, RBA, and GBA criteria instead of being answered again from scratch.
- More than 2,200 Twins are already built from public data, so roughly half of a new supplier's assessment exists before they upload anything.
- Supplier due diligence runs at about 2 hours per supplier against roughly 20 manually, and an inbound questionnaire at about 20 minutes against roughly 4 hours.
Scope. Built for the mine, smelter, and trader end of the chain rather than for component-level bills of materials.
Exiger
Exiger maps sub-tier supply chains down to the raw material and applies AI to surface risk across them, which is why it appears in defense, government, and large manufacturing procurement. The product answers who sits three or four tiers below a Tier 1 supplier.
Coverage. Supplier and counterparty risk in depth, with sub-tier mapping, material-origin tracing, and risk scoring. 3TG is handled as part of that picture rather than as a reporting product. Mining framework readiness and inbound customer requests fall outside the product, so teams that need those run a second system alongside it.
IntegrityNext
IntegrityNext monitors supplier compliance risk at scale, combining questionnaires with continuous external risk data across many industries. Its practical value is standardising what every supplier gets asked, which matters more than it sounds once 900 suppliers are answering in nine different formats.
Coverage. Supplier risk and broad framework coverage, with automated alerts. Depth on smelters, RMI lists, and the mining standards (IRMA, Copper Mark, CMSI) is not the design goal, since breadth across industries is.
Prewave
Prewave scans news and external sources in real time to catch incidents deep in the supply chain before they reach the business. It is widely used in automotive and industrials, where a Tier-3 stoppage becomes a production problem within days.
Coverage. Monitoring only. It will report that a supplier is in the news, and it does not produce a CMRT or a readiness position against Copper Mark, so it sits alongside a due diligence system rather than replacing one.
Assent
Assent has a long track record in conflict minerals and manufacturing compliance, which suits companies where product compliance and 3TG are handled by the same small team. The CMRT workflows are mature and the supplier engagement machinery is built for volume.
Coverage. 3TG reporting and product compliance, with supplier engagement at scale. Upstream mining framework work sits outside the product, so IRMA, Copper Mark, or CMSI readiness is handled elsewhere.
Source Intelligence
Source Intelligence is a specialist in conflict minerals and responsible sourcing, with supplier-outreach automation and validation built for 3TG reporting campaigns.
Coverage. 3TG in depth, including CMRT and EMRT validation and campaign management. Wider due diligence, framework readiness, and ratings sit outside its scope by design.
iPoint
iPoint, based in Reutlingen and owned by GRO Capital, offers product-compliance and conflict-minerals tools for CMRT and EMRT alongside materials-data management, plus an add-on that puts compliance data inside SAP. It is aimed at manufacturing supply chains and organised around parts and materials.
Coverage. 3TG and full-material disclosure for manufacturers. The data model starts from the product and works backwards, which fits an assembly line better than a mine-to-smelter chain.
Benchmark Gensuite
Benchmark Gensuite is a broad EHS and compliance suite that includes a conflict-minerals module, aimed at organisations keeping responsible-minerals reporting inside a system they already run.
Coverage. Conflict minerals as one module among many, with the breadth of an established enterprise deployment. Minerals-specific depth is not what the suite was built for, and the usual reason it wins is that it is already installed.
How to test a shortlist in one week
Every tool here can produce a report and every demo looks competent, so what separates them is how much manual entry the tool removes and whether the data entered keeps working afterwards. Take one real supplier, ideally an awkward one, and run it through two shortlisted tools in the same week.
1.Hand over the evidence as it exists today. Scanned audit PDFs, a half-finished CMRT, a policy in Portuguese. If the tool needs it cleaned up first, that cleaning becomes a permanent job.
2.Ask for smelter validation against the current RMI list, not the version from the last release cycle.
3.Ask for a gap analysis against one framework you care about, with evidence linked to each requirement rather than a score out of 100.
4.Then ask for the same supplier against a second framework. This is where equivalency either exists or the same criteria get answered twice under different names.
5.Forward a real inbound questionnaire from one of your customers and measure how much of it comes back filled.
Tip. Ask for the before and after in hours per supplier and per questionnaire, measured on your own supplier rather than a demo dataset. A vendor confident in those numbers will run the comparison with you.

What implementation involves
Every vendor here will quote a timeline. What moves that timeline is the state of your existing evidence rather than the software, so five questions are worth asking before signing.
1.Who loads the data. Your team, the vendor's onboarding team, or a paid services engagement.
2.What happens to historical evidence. Whether audits and certificates from previous years get structured and reused, or whether the system starts from today.
3.Who chases suppliers. In conflict minerals campaigns this is most of the labour, and it is often the line item that decides whether a tool saves time.
4.What the renewal looks like. Whether the data stays usable if you add suppliers, change frameworks, or reduce seats.
5.What you keep if you leave. Structured evidence you can export is an asset. Evidence locked in a vendor's schema is a rebuild.
How pricing works in this category
None of the eight publish list prices. Across the category, quotes are built from three variables: number of suppliers in scope, number of internal users, and which modules are switched on. Two things are worth establishing early.
Price behaviour as supplier count grows. Per-supplier pricing that reads as reasonable at 40 suppliers can dominate a budget at 400. Ask for the quote at your current count and at double it.
Whether supplier outreach is billed separately. Several vendors in this category price the chasing as a service rather than software, which is the difference between a licence and a programme cost.
How beSirius approaches critical minerals due diligence
beSirius treats due diligence as data rather than paperwork, and everything runs on the Twin. A company's evidence is structured once, then Insight runs it against any framework while Answer fills any incoming request from the same source.
Supplier due diligence
Insight checks a supplier's Twin against your criteria and returns a gap analysis with evidence linked to each requirement, which takes roughly 20 hours of work down to 2 per supplier. Read more →
Conflict minerals
Answer auto-populates the current RMI template from the Twin, validates smelters, and consolidates supplier responses whatever version they arrive in, which removes the need for a separate conflict minerals system. Read more →
Customer requests and KYC
Questionnaires, KYC forms, and self-assessments are filled from the same Twin, so a response takes about 20 minutes rather than half a day.
Ratings
Rating submissions are prepared from the Twin. A CDP Climate and Water submission goes from about 8 weeks to 7 days, and EcoVadis, Sustainalytics, and S&P assessments from about 76 hours to 8 per assessment.
Framework readiness
One Twin is checked against IRMA, Copper Mark, CMSI, GBA, and ResponsibleSteel, with equivalency built in so nothing is answered twice. Read more →
Because the same verified evidence serves every check, due diligence stops being an annual scramble and turns into something you keep current through the year.
"Their model creates a 'sustainability twin' of Gerald's policies and examines publicly available information and documentation provided by the counterparty to assess whether their performance aligns with our standards. The system saves time by highlighting relevant information and providing a comprehensive data repository of counterparties that have undergone a sustainability evaluation. It then generates evaluations and judgments that are ultimately reviewed by the sustainability team for a final decision."

Glossary
Short definitions for the terms used above, in the order they tend to come up.
- OECD five-step framework. The OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas, which most other requirements are built on top of.
- 3TG. Tin, tantalum, tungsten, and gold, the four minerals covered by conflict minerals rules.
- CMRT. Conflict Minerals Reporting Template, the standard form for reporting 3TG through a supply chain.
- EMRT. Extended Minerals Reporting Template, the equivalent for cobalt, mica, and other minerals outside 3TG.
- RMI. Responsible Minerals Initiative, which maintains the conformant smelter and refiner list that CMRT submissions are checked against.
- IRMA. Initiative for Responsible Mining Assurance, a site-level standard audited against social and environmental performance.
- Copper Mark. An assurance framework for copper, molybdenum, nickel, and zinc production sites.
- CMSI. Consolidated Mining Standard Initiative, the effort to merge overlapping mining standards into one framework.
- GBA. Global Battery Alliance, whose battery passport requirements pull mineral-level data into battery supply chains.
- ResponsibleSteel. The certification standard for steel sites and the material flowing through them.
- Equivalency. Where evidence accepted by one framework satisfies an overlapping requirement in another, so the same criterion is answered once.
Frequently asked questions
What is critical minerals due diligence software?
Software that maps supplier and counterparty risk, files conflict minerals reports on 3TG, tracks readiness against mining frameworks, and answers the questionnaires customers send you, all in line with the OECD Due Diligence Guidance. Most tools cover one or two of those four jobs in depth.
How is it different from general supply-chain or ESG software?
General tools cover many industries and focus on reporting, so mining arrives as one preset among dozens. A critical minerals tool knows what a smelter ID is, checks it against the current RMI list, understands IRMA, Copper Mark, and CMSI, and follows the OECD five-step process rather than approximating it.
Do I still need separate conflict minerals software for CMRT?
Not always. Some tools handle conflict minerals inside a wider due diligence workflow, which saves running a second system. beSirius populates and validates CMRT and EMRT from the same Twin it uses for supplier due diligence and ratings.
What is the best conflict minerals software?
It depends on whether 3TG is the whole job or one part of it. Source Intelligence and iPoint focus on CMRT and EMRT handling, Assent pairs conflict minerals with product compliance, and beSirius covers 3TG as one output of the Twin that also serves due diligence, framework readiness, and ratings.
What is responsible sourcing software?
Software that shows the minerals and metals you buy meet standards such as the OECD Guidance, IRMA, Copper Mark, and RMI. It overlaps heavily with conflict minerals tools, and the difference is scope. Responsible sourcing covers the full range of supply chain risk, while conflict minerals software focuses on 3TG reporting.
Which rules drive critical minerals due diligence in 2026?
The OECD Guidance, the EU Conflict Minerals Regulation, and the EU Battery Regulation, plus customer and investor requirements built on IRMA, Copper Mark, CMSI, and RMI, and ratings such as EcoVadis and CDP. In practice the customer requirements tend to arrive faster than the regulatory ones.
How long does supplier due diligence take with software?
Done manually, qualifying one supplier runs to weeks of back-and-forth. With reusable structured data it comes down to a couple of hours, and on beSirius that is roughly 20 hours down to 2.
What does this software cost?
None of the tools on this list publish list prices, so expect an annual licence shaped by supplier volume, number of users, and which modules are switched on. Ask what happens to the price when supplier count doubles, because that is where quotes move most.
What should a small or mid-sized supplier look for?
Repeat work above all else. If evidence can be entered once and reused across every customer request and framework, each questionnaire stops being rebuilt from scratch, which is where the hours go.
