Any company or person who manufactures a dietary ingredient or a dietary supplement—as defined in the Dietary Supplement Health and Education Act of 1994 (DSHEA)—or who distributes a dietary supplement under its own brand shall be eligible for membership in CRN as a Voting Member. Under DSHEA, a dietary supplement is defined as "any product that contains one or more dietary ingredients such as vitamins, minerals, herbs, or other botanicals, amino acids or other ingredients used to supplement the diet."
Dues for Voting Members shall be calculated on the company's previous fiscal year's sales. "Sales" is defined as net sales in the U.S. during the past year resulting from the manufacture and/or distribution of dietary supplements or ingredients in dietary supplement products, including all dietary supplement product sales of the member company and its domestic affiliates, excluding intracompany sales. "Ingredients" includes not only "dietary ingredients" as defined in DSHEA, but also excipients, colors, flavorings, and other ingredients used in the manufacture of supplements. There are four categories of Voting Members—branded finished product manufacturers, contract manufacturers, ingredient manufacturers, and ingredient representatives/distributors. Calculation instructions for Voting Member Dues are on the membership application.
Any company or person who supplies services or other support to a company or person eligible for Voting Membership. Associate Members may apply to upgrade their membership to voting status. CRN now offers a four-tiered dues structure in the Associate Member category, dependent on the size of the company making membership more affordable for single practitioners.
Any company or person that is eligible for Voting or Associate membership in CRN, but does business exclusively outside the U.S. International members may apply to upgrade their membership to voting status.
