Guarantee when importing from China?

The following question: If I want to buy / import original brand electronics (for example an ASUS notebook) as a retailer from China as a retailer - and would like to resell it in Germany… What about the issue of warranty? Do the devices even have a valid warranty in Germany? May I resell such goods in Germany (for example via Amazon)? What else should I consider? (The usual things like customs and import sales tax are clear to me - I import for years from China - but now I want to import and sell high-quality technology for the first time).

I'm grateful for any experience and any information!

Sorry, you can't import as a dealer branded in Germany legal protection → parallel import ban.

Thanks for the feedback. Is there a gray area for no-name products or for brands that are otherwise only available in China and not in Europe?

If the brand is not protected or represented in DE it is no problem.
