To: Customers purchasing Stain HD products

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.

Please acknowledge receipt of this notification and confirm your acceptance of the change by completing the section below and emailing a copy of the form to Acceptance of the change is assumed if a response is not received within two weeks of issue of this notification.

If you have any difficulties or concerns accepting the change, please contact us immediately.

Product: Stain HD Dyes and Stains.

Product code: HD codes, HS codes, HDS codes, HK codes.

Proposed Change Date: 01 March 2022

Change Details:

Stain HD products may be provided in bottles of a larger size than usual.

Reason for Change:

Due to the Covid-19 pandemic the world-wide stocks of plastic products and the polymers used to produce these (including silica) are severely limited. Many bottle types used at TCS Biosciences are now on back[1]order with our suppliers and we anticipate our stocks of some bottles will run out before we receive our orders.


Any larger bottles used to package Stain HD products will be made of the same material as the bottle that is usually used. The volume of product contained within the bottle will be clearly indicated on the label.


We reserve the right to package our Stain HD products in bottles normally used for larger volumes to ensure we can continue to provide these products to our customers. This is a temporary action and we will revert to using the usual bottles for Stain HD products as soon as we receive stocks from our suppliers.
