Yes, if a garment factory counterfeits a trademark, it is illegal for you to help do it. If found out by the industrial and commercial department, not only the manufacturer will be fined, but you will also be fined, and all labels with that trademark will be fined. All must be replaced, and all those that have been shipped must be taken back. There are regulations in the trademark law. It is best to ask the manufacturer to provide you with the trademark registration certificate, and then go to the official website of the Trademark Office to check to see if it is Not true.
