System introduction

The EU REACH Registration Enquiry System is to help potential registrants to access the information of costs for thousands of phrase-in substances registrations under EU REACH, such as the cost of Letter of Access (LOA) charged by Lead Registrant (LR), administration fee charged authority or other potential costs involved. The system could not only help users to estimate the cost for REACH registration but also to get other relevant information such as lead-time and procedures for EU REACH registration.

The System is a free tool. CAS number is preferred when you fill in the substance identity form. In addition, the users shall also input registration type, tonnage band, enterprise size and email address.

According to REGULATION (EU) 2016/9 (Data sharing Regulation), the LOA cost is shared by all actual registrants and subject to change. We will try to get the most up-to-date LOA cost, but the accuracy of the cost is not guaranteed. If you have any other questions, please send email to
