TSCA applies to naturally occurring and chemically reactive chemicals themselves, chemicals in mixtures, and intentionally released chemicals in articles. It is important to note that chemicals defined by TSCA also include microorganisms. If your products are pesticides (excluding pesticide intermediates), nuclear materials, food, food additives, pharmaceuticals, cosmetics, or medical devices, a TSCA exemption declaration is required; If your product is a TSCA controlled chemical, mixture, or article containing an intentionally released substance, you are required to provide a TSCA compliance statement.
