Broker Members 

Broker members are those companies allowed to issue LME contracts - buying and selling material on behalf of their customers. Companies can become Ring dealing or associate broker clearing members if they are also members of the clearing house. Those companies who do not wish to clear business, may decide to become associate broker members.

Trade Members

Trade members are industrial or financial companies with a key presence and interest in the metal industries. Companies with operations in these areas may decide to become associate trade members. This category of membership is sought primarily to keep abreast of LME activities, its contracts and their development and news on the Exchange itself. 

Companies that are also members of the clearing house can join as associate trade clearing members to trade and clear their own business.
