IMCA Membership Application

The first step in applying for membership is to create an account for this site which will let you start the application process, give you access to come back and update your application, check on the status of your application and update contact details.

To apply for membership, start by selecting the appropriate category below.

  • You must apply for the highest category relevant to your company's operations. You may wish to use our member directory to help identify where similar companies fit into the category structure.
  • Applications should be submitted by named individuals via a personalised company email address.
  • Please do not submit in ALL CAPITALS, as this creates additional work restoring to a normal format.

A copy of the application form is available in Microsoft Word format to help you prepare the required information, but all applications must be submitted online via this page.
