Trade associations are organizations that are formed by businesses or individuals within a particular industry. They exist to promote the interests of their members and to improve the overall image and reputation of their industry. Although the term "trade association" is commonly used, there are several synonyms that can be used to describe these types of organizations. For example, they may also be referred to as industry associations, business associations, professional associations, or chamber of commerce. Each of these terms denotes a slightly different focus or emphasis, but they are all used to describe groups of businesses or professionals working together for a common purpose.
