Shipping mesquite via UPS

My parents asked me to post this: my dad wants to ship some mesquite for grilling a brisket by UPS to my uncle in North Carolina. Are there any restrictions or things one needs to know before shipping raw wood?

Have you contacted UPS?

I read through the website, but couldn’t find any specific information.

I can buy bags of mesquite at my local Home Depot year around. Is there something special about your dad’s?
