Apply for membership
Membership in the Salt Institute is restricted to salt producing companies. This is narrowly defined as companies which both produce sodium chloride and sell sodium chloride. Chemical companies with their own brine wells do not qualify; they produce sodium chloride, but don't sell it as salt. Neither do salt distributors or those who sell salt-derived products (e.g. salt lamps); they are selling salt, but they don't produce salt, they buy it from a salt producer. Don't apply for membership unless your company both produces salt and sells it as salt.
There are two classes of members, the distinguishing feature between them being their involvement in the North American salt marketplace where the Institute devotes a major share of its resources. Regular members are U.S. based companies; non-U.S. companies can be invited to become regular members if they have significant North American market presence. Other member companies are Associate members.
Dues are based on salt sales in the U.S. and Canada. Members report such sales semi-annually to the Institute's accounting firm which maintains these reports in confidence but which produces a Statistical Report of U.S. Salt Sales and which administers quarterly invoicing of dues. Dues are based on U.S. sales. For regular members, dues are about two cents per ton for bulk salt ($0.021305737 per ton) and between $0.000770769838 and $0.001037480272 per revenue dollar for various types of packaged salt. Minimum dues for regular members are $12,000. Associate member dues are also based on the number of tons sold in the U.S. Importers of 100,000 tons or less pay the minimum dues of $5,000; this is scaled upwards for companies with larger import sales.
Salt producers wishing to join the Institute should complete and submit an application form expressing their desire to join the Institute, a willingness to accept their membership and dues responsibilities, and including a description of their operations sufficient to establish that their company both produces and sells salt.
