Direct transport requirement ensures preferential origin when goods move directly, subject to transit and trans-shipment conditions. The rule requires direct transport for originating goods to qualify for preferential origin: direct movement may pass through Signatory Parties or transit through third countries under customs surveillance provided the transit is justified by geography or transport needs, the goods are not intended for use or trade in the transit territory, and no operations occur other than unloading, reloading or preservation (including temporary warehousing or trans-shipment).
