Hazardous Materials Information Review Act (HMIRA) Claim for Exemption – Is disclosing your chemical identity a RISK to your company?

By: Kirsten Alcock, Manager of Product Safety, email

Many companies would like to keep the composition information about their product confidential.  Under the Hazardous Products Regulations (HPR) in Canada, the composition of their product must be disclosed on their SDS in section 3 (if hazardous).  Health Canada allows for Trade Secrets on SDS or protecting their “CBI – Confidential Business Information” if you APPLY for one.  In Canada, if you would like to keep your chemical a Trade Secret on your SDS, you must do a Trade Secret claim through HMIRA.

Does disclosing this particular chemical on a Canadian SDS pose a risk to your company if it’s disclosed to your competition?  If you don’t hide the CAS number, will your competition be able to replicate your product and sell to the Canadian workplaces?

 Below you will find some information on what HMIRA is and what is required to claim Trade Secret on an SDS in Canada.

When can I start using the HMIRA Registry #?

As soon as you receive it. You may not send your SDS out claiming Trade Secret without this registry number.

How long does a HMIRA Registration last?

A HMIRA registry number expires after 3 years. If the formula changes or new information changes the SDS classification, a new registration must be applied for.

A new HMIRA Registry number is assigned with every renewal.

What is a Generic Chemical Identity?

Terms such as “trade secret”, “proprietary”, “confidential” “surfactant”, “solvent” are not permitted in place of a chemical identity on a Safety Data Sheet.

The Safety Data Sheet must use a Generic Chemical Identity (CGI). The objective is to mask part or all of the chemical name while at the same time retain identity of the general class or structure so that it can still be connected to hazard information disclosed on the Safety Data Sheet.
