Your research fees are subject to disclosure under §230.4(b)(4) if they apply to CD accounts. Accordingly, if you "up" those fees, and intend to apply them to your current CD accounts, you'll want to notify them.
Photocopying and cashier's check fees, however, are charged to customers and non-customers alike, aren't they? If so, these fees are not subject to disclosure under §230.4(b)(4) and you would not need to provide 30-day notice of those changes.
