Keep in mind that it is up to the organization to determine who their interested parties are and what of their requirements are relevant to your quality management system.
If you follow the concept of interested parties too deep into the bunny hole you could end up with every entity in the universe. Use a bit of reasoning and logic to determine who the most pertinent ones are.
Make sure you understand the requirements of element 4.2 and that you are able to explain your position.
For a reasonable potential list of interested parties see ISO 9002:2016, but don't get the impression that this guidance document is trying to tell you that you need to include all of the ones they are suggesting you consider.
