Pick a single product you want to import into the US, state country of origin, country shipped from, quantity, value, etc. and be specific. State what Customs will expect of you as an importer; what documents will you have to have, what documents might you need; and explain what information each document gives US Customs. Was there information you needed to send to Customs prior to the export of your product to you? Please mention all the reference link as well. Thank you!
