The USB-IF offers a Qualification by Similarity program to member companies that have USB-IF certified or EU conformity to IEC 62680 products.  The QbS program enables a new USB product to be certified or receive EU conformity to IEC 62680 status based on its similarity to a fully tested and certified USB product.  The purpose of the QbS program is to speed time-to-market and to reduce compliance testing costs.  It is not intended to eliminate the requirement that a product actually pass USB-IF compliance or EU conformity testing.  For more information regarding the USB-IF Qualification by Similarity program, please see the QbS Introduction webpage.

The USB-IF Certification Program and/or EU Conformity program only tests and certifies or issues EU conformity to IEC 62680 status to a specific name, model and revision number of a USB product.  A product with a slightly different name, model number or revision number is not considered certified or conforming to to IEC 62680 status.  In addition, the USB-IF does not allow the use of variables in the product's name, model number or revision number in order to define a family of products.  Please use the Qualification by Similarity program to obtain certification for closely related products.

The USB-IF EU Conformity to IEC 62680 Program has the same registration requirements as the USB-IF Certification program, however it allows an external power supply or portable battery powered device to achieve conformity to the USB Specifications (IEC 62680) referenced in the EU legislation for EU External Power Supply (EPS) Ecodesign legislation and the Common Charger Directive. This program is a subset of the USB-IF Certification programs for USB-C and USB Power Delivery. More information can be found on the USB - EU Conformity Compliance webpage.

The USB-IF accepts Qualification by Similarity requests via online forms.  The forms should work using modern Chrome, Internet Explorer/Edge or Firefox browsers.  The online forms have been updated to allow multiple similar products to be declared in a single submission.  Be aware your usb.org login credentials are required to access the forms. 

If your organization is a member of USB-IF and you do not have login credentials, you can register for a usernmame and password.
