Well let’s see. You ask a question because, I assume, you don’t know how to do it.
Then you ask if you “really need” someone who does know how to do it.
You don’t need a broker if you know how to make a customs declaration and how to verify any phytosanitary, agricultural, and food regulations that might be in place.
However if you don’t know all of those things I’d say you need a broker.
