Listing and approval use and compliance are standards set by organizations and businesses to make sure all products and services they use are safe and meet the requirements to be legally sold. Companies have to make sure their products, such as food, toys, or electronics, meet certain standards set by the government so that the products are safe for the people who use them. Companies have to prove to the government that their products and services meet the standards by showing that they have followed all the necessary steps and that they have been tested and checked by specialists. This is called listing and approval use and compliance, and it is important to make sure that companies are following the rules and that people stay safe.
