Conflict Minerals


Conflict Minerals legislation arose from an amendment to the financial regulation laws in the United States of America in 2010, known as the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2009. In summary, all US companies that have to file their yearly finance reports with the Securities Exchange Commission (SEC) had to start reporting on whether their source for 4 substances is from a conflict-free source.

The 4 substances are:

  • Tantalum (Columbite-tantalite ore, or coltan)
  • Tungsten (Wolframite ore)
  • Tin (Casserite ore)
  • Gold

These four are sometimes referred to as 3TG (in reference to their initials).

The main area of conflict mines (i.e. mines that are being used to support internal conflict in a region) is in the eastern region of the Democratic Republic of Congo, along with the nine neighboring countries. Further information can be found on the website for the Responsible Minerals Initiative (previously called the Conflict Free Sourcing Initiative or CFSI).

Harwin’s position

Our current company policy on Conflict Minerals is available here.

Harwin do not report to the SEC, and as such are not required to submit a conflict minerals report to the US Government. However, because of the global interconnected supply chain, we are asked to report on our conflict mineral status.

Harwin use the industry standard Conflict Minerals Reporting Template (CMRT), released by the Conflict Free Sourcing Initiative. Our Company CMRT is available from the Legislation page - second item listed.

We also have provided Product-specific CMRTs for almost all our standard products. The easiest way to locate the correct CMRT for the product you require is to search for the product using the search bar in the top of the page. There is a link for the CMRT under the Legislation area in the lower half of the page.


If you require a CMRT for a product not listed on our website (such as a custom manufactured product), please contact [email protected] for assistance.

Currently, Harwin has not located any conflict minerals in our supply chain. We will continue to pursue the information from our suppliers and repeat these investigations on a regular basis. If you have any questions on this topic, do please contact [email protected] for assistance.
