Opening a Sigma-Aldrich Account

Accounts are generally established for a company or institution rather than for individuals. Before attempting to establish a new account, please check with your organization’s purchasing department to verify whether an account with Sigma-Aldrich already exists.

When you are ready to place your order, call our Order/Customer Service number and provide the Sigma-Aldrich service representative with your shipping and billing information. The service representative will ask your some questions about your general business, along with taking information about the products for your order. Our New Account Department will then verify this information, as well as validate your intended use of our products. You may be contacted for further clarification; however, we will take quick and suitable action to establish your new account. To further expedite our process, please have a credit card available to pre-pay your first order. For information regarding the appropriate uses of Sigma-Aldrich products, please refer to our Terms and Conditions.
