For items sent to the United States, it is necessary to indicate the name, quantity, value, and origin of the item on the package. Generally speaking, if the value of an item exceeds $200, the package must indicate the origin and value of the goods. In addition, invoices or detailed forms of goods need to be provided so that US customs can clear customs based on the actual type and quantity of items in the package. If an invoice or detailed list of goods cannot be provided, customs will estimate the price of the goods based on their market value.
