I do not know about ANSI but for ISO/CS the quote given below from http://www.iso.org/iso/en/prods-services/iso3166ma/02iso-3166-code-lists/ind ex.html is certainly correct.
We make a distinction between implementation and commercial use.
I have no idea how they manage to get their heads around this one.
Anyone can buy the standard - or download the codes from our website free of charge - and use them within their company for any application they want without having to pay any licence fee due to ISO.
However, if you load the list of country codes and names in a commercial product, thus giving an added value to your product, we consider it normal that ISO asks for the payment of a royalty fee. Purchasing an electronic copy (e.g. one of the MSAccess databases) from our Web store gives you only the same right i.e. if you want to create a for sale product licence fees can apply. (But one can choose another possibility which is to let customers download the country codes.)
Implementations like drop-down lists on webpages or the use of ISO 3166-1 codes in software implementing other standards which quote ISO 3166-1 as normative reference is of course not subject to a licence fee.
I am not an expert on these matters and I would suggest that you contact Mr Chabot to discuss details with him should you have further need for clarification.
