My wife and I are finalizing plans to start manufacturing and shipping products from China to the US to be sold by our new company. The total value of the products will be $10-15k. We're confused about the duties and tariffs end of things. Our manufacturer says that the price they quote will contain all duties and tariffs, but I just want to make sure they know what they're talking about and want to verify it for myself. Does anyone have any experience with this? Any good resources to look into? Thanks for any info!
