An example of an invisible item of trade is shipping. Invisible items of trade refer to goods or services that cannot be seen or touched, and are not physically transported across borders. Shipping, as an invisible item of trade, refers to the movement of goods by sea, air, or land transportation. Although the ships, planes, and trucks used to transport goods can be seen, the actual transportation service itself is intangible and cannot be touched. Despite being invisible, shipping plays a vital role in international trade, as it enables the movement of physical goods between countries.
