Nearly 80 per cent of U.S. public companies analyzed by human rights groups are failing to adequately check and disclose whether their products contain conflict minerals from Central Africa, a new report by Amnesty International and Global Witness reveals.

The report, Digging for Transparency, analyzes 100 conflict minerals reports filed by companies including Apple, Boeing and Tiffany & Co under the 2010 Dodd Frank Act (Section 1502), known as the conflict minerals law. The findings point to alarming gaps in U.S. corporate transparency.

Under the law, more than one thousand U.S.-listed companies that believe they may source minerals from Central Africa submitted reports to the U.S. Securities and Exchange Commission (SEC) in 2014, the first year they were required to do so. The law is designed to reduce the risk that the purchase of minerals from Central Africa contributes to conflict or human rights abuses.

“The conflict minerals law is an opportunity to clean up global mineral supply chains. But our analysis shows that most companies seem to prefer business-as-usual to genuinely addressing the risk that their mineral purchases bankroll armed groups overseas,” said Carly Oboth, Policy Adviser at Global Witness.

“This is alarming. Well-funded industry groups have fought the conflict minerals law at every step. If companies had instead spent these resources on properly investigating and reporting on their supply chains, their customers would be more confident their goods were conflict free.”

The Democratic Republic of Congo (DRC) is an important source of minerals – including gold, tin, tungsten and tantalum – for global businesses. These minerals are essential for electronic devices, such as smartphones and laptops. For over fifteen years armed groups in eastern DRC have preyed on the mining sector to finance their operations with devastating impact, committing gross human rights abuses in the process.

The report’s key findings include:

79 of the 100 companies analyzed failed to meet the minimum requirements of the U.S. conflict minerals law.

analyzed failed to meet the minimum requirements of the U.S. conflict minerals law. Most companies in the sample are not doing enough to map out the supply chain of the minerals they purchase. Only 16% go beyond their direct suppliers to contact, or attempt to contact, the smelters or refiners that process the minerals.

go beyond their direct suppliers to contact, or attempt to contact, the smelters or refiners that process the minerals. More than half of companies sampled do not even report to senior management when they identify a risk in their supply chain.

Global Witness and Amnesty International’s analysis also shows that one in five surveyed companies did comply with the law’s requirements. This dismantles the argument put forward that implementation is too difficult and too expensive – there is no excuse for companies failing to properly investigate their supply chains.

“Consumers want to know what lies behind the logo. Companies are under pressure to show they leave no stone unturned in their efforts to make sure products on the shelf don’t hide a terrible story of conflict and human rights abuse. A box-ticking exercise just won’t cut it,” said James Lynch, Head of the Business and Human Rights Team at Amnesty International.

“Companies that shed light on their supply chains help prevent a harmful mineral trade that contributes to a conflict devastating Central Africa.”

Dr. Denis Mukwege, the acclaimed Congolese surgeon and humanitarian, said: “Companies must do more to find out how the minerals they are buying have been produced and traded… In June, when companies file their second conflict minerals reports, they must show that they have put this right.”
