How do I join?

Sedex offers three different types of membership. Before joining Sedex, you first need to determine which membership type is best for your organisation.

If you are not sure which membership type is suitable for your company, please visit our ‘Membership options’ page, where we have put together some questions to help you with this decision. Once you know which membership type you wish to apply for you will need to complete the online registration form.

If you need further assistance please contact the Helpdesk. Support is available in English, French, Spanish, Portuguese, Turkish, Russian and German. Chinese speakers can access support by contacting the China Helpdesk.

Buyer (A) and Buyer/Supplier (AB) Members

Once you have completed the registration form, your details will be passed to our Business Development team who will contact you to discuss the next steps.

This is an essential step in the registration process as we can advise you on the most appropriate membership model for your organisation and fully explain the benefits that will be included in your service package.

Supplier (B) Members

Upon completion of the registration form you will be sent an email containing your log-in details and payment information.

Before you can start using your Sedex account you will need to pay your membership fee.


To do this you need to log in and create your invoice in order to arrange payment by credit or debit card or by bank transfer. Please click here for more information on the payment methods available.
