The same description in the catalog on the website of the manufacturer and suppliers of the same product. How does it affect indexing?

Question

Search Engine Optimization

Hi all!
Guys help with this question. In general, there is a gate manufacturer's website www.doors.ryterna.eu/ru and there is a supplier of these gates to another state. Duck, this supplier ordered a website and says that they say I sell their products, take all the texts, descriptions from their website to describe the products.
Well here's a question. How then will the search engines react to such acts? Maybe somehow you can explain to the search engines that this is not a duplicate?
