Companies should send a clear message that they are dedicated to sourcing their minerals responsibly. Having a separate page on its website about conflict minerals or responsible sourcing is a sign that the company takes this issue seriously.
The trade in minerals has been linked to conflict and human rights abuses in countries such as the Democratic Republic of the Congo, the Central African Republic, Afghanistan and Colombia. These minerals – sometimes called “conflict minerals” – are used in a wide variety of goods we use every day like smartphones, laptops and cars.
Use your preferred search engine to search for “[Company name] conflict minerals” or "[Company name] responsible sourcing" – when the company is well known this search should give you some high-ranking results that are pages on the company’s website. For companies that are not so well known, you may wish to limit the search to their official website (e.g. "site:http://xiaomi-mi.com conflict minerals” or "site:http://xiaomi-mi.com responsible sourcing”– in Google search).
Having a page on its website dedicated to conflict minerals or responsible sourcing means that the company goes beyond simply having a "Conflict Minerals Policy". You can find more information about a company's Conflict Minerals Policy through Conflict Minerals Report.
Where the company has a page on their website dedicated to conflict minerals or responsible sourcing, they should receive a value of “Yes” and you should add a link to this page as the source. Where you cannot find a page on the company’s website that is dedicated to conflict minerals or responsible sourcing, set their value to “No” and make a “report” source – describe the domain you searched and give the date (e.g. "xiaomi-mi.com searched on 15th December 2015, no page about conflict minerals / responsible sourcing found").
