TCS BIOSCIENCES LTD, CHANGE NOTICE: CCI 70A To: Customers and Distributors of StainHD product range. It is our intention to change the Manufacturing Process of the products listed below. The details of the change and the reason for it are given below. If you have any difficulties or concerns accepting the change, please contact us immediately. Product: StainHD product range (see list below) Proposed Change Date: From 1 June 2021 Details: We are discontinuing some of the products and/or pack sizes from our current catalogue of StainHD products. Reason for Change: Due to the current Covid-19 pandemic TCS Biosciences is focussing our production activities on our core products. We have reviewed our range of StainHD products and identified those products and pack sizes that are slower selling. Some products will be discontinued from the range and some other products will have fewer pack sizes available than currently. See list below Note – this list is not exhaustive and TCS Biosciences reserves the right to include further products as necessary. Considerations: This change control is issued to give three months’ advance notice prior to implementation of the change.
