In the event of delay in opening cases, containers or packages, any loss or damage discovered upon opening shall be deemed to have occurred during transit and shall be paid for accordingly unless conclusive proof of the contrary be established. Cases, containers or packages showing outward signs of loss and/or damage are to be opened immediately on arrival.
This agreement shall, however, only apply where such loss or damage is discovered within ninety days of arrival of goods at consignees or other final warehouse.
