An organization formed mainly by traders and manufacturers to cater for the interest of their members is called a "trade association". Trade associations are formed to promote the common interests of its members, such as lobbying for favorable government policies, providing industry-specific training and education, and networking opportunities. They may also provide information and support to their members regarding legal and regulatory issues, industry trends, and best practices. Trade associations often have a specific focus or specialization, such as regional or national representation, a particular industry sector or product, or a specific trade or professional group.
