Luggage is a high-volume, low-weight product, making shipping costs a significant portion of the TCO. To optimize costs, request the factory to use 'nesting' packaging (placing a 20" cabin bag inside a 24" medium bag, which is then placed inside a 28" large bag). This drastically reduces the CBM (Cubic Meter) volume and shipping fees. For international trade, clarify Incoterms clearly—FOB (Free On Board) is generally preferred for buyers who have their own freight forwarders to control the sea freight costs.
