Changes to Merck Life Science and Sigma-Aldrich Legal Entities: Impacts on Web Shop and Ordering

  • On July 1, 2021, the commercial business of Merck Life Science in the Poland has been restructured.
  • This business previously operated by two legal entities, Merck Sp. z o.o., and Sigma-Aldrich Sp. z o.o.
  • The commercial business was consolidated into Sigma-Aldrich Sp. z o.o., which at the same time was renamed to Merck Life Science Sp. z o.o.

You will benefit from this development since Merck will serve the customers of its Life Science business in Poland via one legal entity, as opposed to two entities, neither of which could provide customers with access to the entire Merck Life Science portfolio.

For a smooth transition, the ordering and sending of goods was limited during the transitional period, the first day for sending the order to Merck Life Science Kft. was July 5, 2021.
