Definition

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.

Additional Info

It's no secret that Safety Emporium is your source for US-manufactured NIOSH-approved N95 surgical respirators and more.

New Jersey state law 8:59-3 sets the standards for trade secrets. Per 8:59-3.6, the TSRN is derived in either of two ways:

• By adding a numeral beginning with "5000" at the end of its New Jersey Department of Labor employer identification number (EIN), separated by a dash, and preceded by the words "Trade Secret Registry #." Each new trade secret registry number shall be numbered consecutively. Examples of acceptable numbers include:
  
  Trade Secret Registry Number 12345600-5000
  Trade Secret Registry # 12345600-5000
  TSRN 12345600-5000
  NJ TSRN 12345600-5000; or
  
• By using its own alpha and/or numeric numbering system. If this option is chosen, the trade secret registry number shall be preceded by the words "New Jersey Trade Secret Registry Number." The acronyms and symbols "NJ," "TSRN," "TSR," "No.," and "#" may be used.

Note: In New Jersey EIN's are the same as the company's IRS-assigned employer identification number, EIN.

There are detailed procedures that a manufacturer must follow in order to claim and register a trade secret in New Jersey. See the link to the New Jersey Administrative Code under Further Reading for further explanation.

SDS Relevance

TSRNs will appear on an SDS whenever a New Jersey manufacturer wishes to withhold the chemical identity of a product or its components by claiming a trade secret. Few materials meet the requirement for trade secret, so this term appears on only a relatively small number of SDS's.
