In many cases the containers, cases or packages do not show signs of any visible, external damage and buyers take a clean delivery. Subsequently, damages or shortages may be discovered which insurer would refuse to pay or ask the buyer to prove that the loss or damage happened during the insured transit. This clause gives a benefit to the insured/consignee by stating that if the loss is discovered on opening the containers, cases or packages within the pre-arranged number of days after arrival the loss or damage shall be deemed to have occurred during the insured transit.
