TSRN, New Jersey Trade Secret Registry Number


A New Jersey Trade Secret Registry Number (TSRN) is a code that chemical manufacturers in the state of New Jersey are required to list on their SDS's or labels when they want to withhold the chemical identity of one or more components as a trade secret. Some sheets use the acronym NJTS or TSR in place of TSRN.

TSRN's may apply to ingredients or products that are hazardous or non-hazardous but should not be used for substances that are carcinogens, mutagens or teratogens.
