3TG (Tin, Tantalum, Tungsten, Gold)

3TG is the collective abbreviation for the four minerals designated as conflict minerals under U.S. Dodd-Frank Section 1502 and EU Regulation (EU) 2017/821: Tin, Tantalum, Tungsten, and Gold. These four minerals and their ores (cassiterite for tin, coltan for tantalum, wolframite/scheelite for tungsten, gold doré for gold) are the scope of all conflict minerals reporting obligations under the CMRT, Form SD, and EU Regulation.

Dodd-Frank Act Section 1502; SEC Rule 13p-1; Regulation (EU) 2017/821, Annex I.

3TG is the industry shorthand that every compliance professional should know. When customers, auditors, or regulators refer to conflict minerals, they mean 3TG. The CMRT covers 3TG exclusively (the EMRT covers battery minerals; the AMRT covers additional minerals). Any company that manufactures or imports products containing 3TG must assess conflict minerals obligations. All four minerals require annual RCOI, smelter identification via CMRT, RMAP verification, and (if applicable) Form SD or EU Regulation compliance.

A semiconductor company’s product line contains all four 3TG minerals: tin (solder), tantalum (capacitors), tungsten (via heavy metal contacts), and gold (bond wire). The company collects CMRT data from all suppliers, identifies 200+ smelters globally across all four 3TG minerals, verifies RMAP status for each, and files Form SD by May 31 annually.
