Landed cost.

What a unit actually costs once it is in the buyer's hands: the print and the blank plus freight, duty, brokerage, insurance, and handling. It moves with the route, the Incoterm, and the HS code, not only with the product, which is why two identical shirts can land at different costs. Since the US de minimis exemption ended, duty applies to cross-border parcels of any value, so pricing off the print-and-blank figure alone leaks margin on every order that crosses a border.
