Manisha this side,
Sir, If you are going with private label brand then it is mandatory to have trademark now.
And for a private label brand name trademark, it is mandatory to have an authorization letter from the manufacturer in some cases.
Authorization letter is a letter in which manufacturer authorize you to sell their product under your brand name on their letterhead.
Manufacturer surely gives you brand authorization, traders can’t provide authorization. In case if your manufacturer not providing brand authorization then you should look for another manufacturer. I hardly saw any such case, they happily provide authorization letter.
Best Regards. 🙂
