How to apply to manufacture aerosol containers and gas cartridges

Obtain a copy of the applicable standard, CGSB 43.123 from the CGSB.  Once obtained, review the standard, in particular the design and manufacture sections to make sure your facility is in compliance.

Clause 7 of CGSB 43.123 then lays out the registration requirements and what must be submitted in your application for registration with Transport Canada.

If you are in the business of making DOT specification aerosols in accordance with 49CFR, note that the primary differences between 49CFR and CGSB 43.123 requirements are:

  1. Requirements of what must be submitted for registration (Clause 7)
  2. The marking that must be on the can
  3. If you are making plastic aerosols, CGSB 43.123 requires a 4th batch of samples conditioned at low temperature for the drop test.

Examples of the type of information expected to be submitted for each part of Clause 7 are below.  If successful, you will receive a Certificate of Registration for your facility.
