What type of substance is defined as without authorization bearing the trademark of a different manufacturer?

A counterfeit substance is specifically defined as a material that is not produced or authorized by the manufacturer whose trademark appears on the product. This means the product is intended to mislead consumers into believing they are purchasing a legitimate item, when in fact, it is not. The use of another manufacturer’s trademark without authorization directly violates trademark laws and is a form of trademark infringement, as well as often being connected with illegal activities, especially in the context of pharmaceuticals and controlled substances.

This definition distinguishes counterfeit substances from controlled substances, controlled substance analogues, and deliverable substances, which have different legal implications and regulatory frameworks. Controlled substances are those that are regulated under control laws due to their potential for abuse. Controlled substance analogues refer to substances that are chemically similar to controlled substances but not explicitly listed in the law. Deliverable substances could point to any substance intended for distribution but do not capture the essence of the unauthorized trademark use that defines a counterfeit substance.
