Business chambers and trade federations are membership organisations that represent businesses in a particular area, sector or profession. They provide a forum for members to share information, make professional contacts and discuss issues affecting their work. Chambers of commerce generally serve businesses across a range of industries, while trade federations often focus on the interests and needs of a specific trade or sector. Services can include networking events, seminars, business advice, training and updates on relevant legislation, markets or industry developments. These organisations may consult members, make representations to government and other bodies, and promote the interests of businesses locally, nationally or internationally. Some chambers also provide practical trade services, such as export documentation and certificates of origin.
