Restricted substances declaration

The many processes used to manufacture semiconductors are complex and delicate, and require a variety of specialized chemicals and materials. To protect our employees and the environment, we have several programs in place that regulate our use of hazardous chemicals or "substances of concern". In fact, we follow some of the toughest practical standards in the industry.

We carefully monitor our use of substances categorized as restricted, hazardous, or relevant, and have committed, as part of our near-term Sustainability Program, to achieving a 100% reduction of all restricted and hazardous substances that aren’t critical use. We track our usage of chemicals in our company-wide Chemical Management program, which registers and classifies the chemical substances we handle. Any use or emission of restricted or hazardous substances must be covered by internal dispensation, so we are searching for alternatives as quickly as possible.

The Nexperia List of Hazardous Substances in Products and Packaging specifies substances that are not permitted in materials, parts, semi-finished goods and products at levels above our established threshold to ensure that no Nexperia products put on the market contain any substances that are restricted by law or other regulations, including the European Union’s Directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment (commonly known as RoHS).

While most substances on this list are not permitted by law, a number of them are not permitted by Nexperia in view of upcoming legislation, their impact on the environment or on health & safety.

The Nexperia List of Hazardous Substances in Products and Packaging also contains a number of Restricted Substances. Use of these substances is allowed, but any use of these substances must be reported above the declaration threshold as specified in this list. Most substances are placed on this list because of health risks in their use and/or processing. Others are placed on this list because they limit recycling, because they are scarce or they have for instance a high environmental impact in mining.
