The post does appear a bit outdated.

You don't requite the import/export license for personal use as a hobbyist or collector. Some folks have noted that different border crossings may have different numbers of animals that constitute commerical use, so I would make sure to call ahead for clarification that your X number of "personal use" animals won't require additional paperwork (regarding import/export license) just to be safe & if you're looking at more than half a dozen animals.
The same page further down confirms you also don't pay for the inspection fees if your shipment doesn't require the import/export license.
