The Merchandise Marks Act 1887 (50 & 51 Vict. c. 28) was an Act of the Parliament of the United Kingdom.
The Act stopped foreign manufacturers from falsely claiming that their goods were British-made and selling them in Britain and Europe on that pretence.[1] It also makes it illegal for companies to falsely claim that they have a Royal Warrant.[2]
