Aren’t there too many codes out there? Doesn’t it get too confusing to figure out how to follow codes? How should licensees comply?

There are indeed many different codes of conduct, but, in reality, most of the codes are very similar. Most have language on the same general provisions, and most codes reference international and domestic law. Factories making a good faith effort to comply with national laws and widely-recognized international standards are, in most cases, going to be in compliance with the WRC model code and the codes of WRC affiliates.
