Import commercial permit

I cannot seem to find the form to get licensed to import insects from Belize (non cites). While I have had them sent to me by someone else with the import permits once in the USA, I'm thinking I need to get it to 'be on the safe side.' Exotic Imports, can you tell me where/how to download the application? FYI I am going to be in Belize in July/August.

Thanks in advance
