How To Find Out What Legal Guidelines The Products You Sell Are Subject To

How can I find out what legal guidelines the products I sell are subject to?

Most products and services are subject to some form of guidelines, one way or another, since most industries have some sort of trade body or association that stipulates what those are. They might be on a website, they might be on brochures, there may be literature, and so forth. That is the place to start to find out what the laws are, and guidelines and regulations about your particular industry.
