Can i sell branded product in my Shopify store?

No, We do not recommend adding branded products to your store without getting a licensee to sell their products. 

To be on the safe side, you can choose not to sell products that have any kind of branding or contact these brands to be an authorised reseller of their products before you list them in your store.

Note: Zonify gives you the ability to import products to your Shopify store, but It is your responsibility to ensure you're not violating any copyright and trademark laws.
