Policy Regarding Conflict Materials

NewMarket Corporation strives to maintain high standards of ethical conduct and integrity in all areas of our business activities.

Many industries rely on certain minerals, including gold, tin, tantalum and tungsten, to produce components used in their products. The Democratic Republic of Congo (DRC) in Central Africa, and several surrounding countries, is one region where these minerals are mined extensively. The DRC has been in conflict since 1998, and the resulting hostilities and human rights abuses are supported by the trade of what is known as conflict minerals.

Although we do not typically manufacture products known to contain gold, tantalum, tin and tungsten, NewMarket is committed to not purchase from known conflict sources, and expects its suppliers to abide by the same standards.

As a publicly-traded U.S. headquartered company, NewMarket complies with the Dodd-Frank Wall Street Reform and Consumer Protection Act, Section 1502 and the implementation guidelines published by the U.S. Securities & Exchange Commission, which require supply chain reporting and reasonable due diligence with respect to the sourcing of conflict minerals. NewMarket supports our customers’ efforts to reach the common goal of ensuring a socially and environmentally responsible supply chain.
