Although they mention their due diligence is continous, they do not specify how the monitor suppliers where issues/risks have been identified.
"Our due diligence is an ongoing process, both proactive and reactive, where suppliers are evaluated against our conflict mineral risk categories on a continuous basis to facilitate conflict mineral compliance in the suppliers’ processes.
Our due diligence process categorizes suppliers’ responses regarding 3TG under one of the following six conflict mineral risk categories (“DRC or an adjoining country” has the same meaning in this context as “Covered Countries”):
1. Free/No 3TG - 3TG is not intentionally added to the product and not necessary to the production of the product.
2. Free/Not From DRC - The 3TG being used in the product do not originate from the DRC or an adjoining country.
3. DRC/Conflict Free - The 3TG being used in the product originate from the DRC or an adjoining country; however, the smelters and refiners have been designated as “conformant” (formerly “complaint”) or “active” by the RMI under its Responsible Minerals Assurance Process (“RMAP”).
4. Undetermined/Not from DRC - The 3TG being used in the product do not originate from the DRC or an adjoining country, but to date the supplier has not provided complete information on all of its sources of supply.
5. Undetermined/from DRC - The 3TG being used in the product originate from the DRC or an adjoining country; however, the smelters and refiners have been designated"
