Seeking Guide for Canada to USA Wholesale Shipping

Hello. I am a Canadian manufacturing company specializing in furniture and home décor. I'm in the process of moving from a made-to-order B2C model to a wholesale B2B model. I'm in need of someone with experience to help me understand the legal and financial obligations of shipping wholesale products from Canada to US retailers. What labeling is required? What duties will there be? How will sales taxes work? That sort of thing.
Thanks!
