The formal process is for the buyer to unpack and inspect the goods first, and then sign to receive the goods after confirming that they are correct. However, many express delivery methods follow "irregular" processes. From their point of view, it is nothing more than taking responsibility. It is of course best if there is no problem after opening and inspecting the goods. If there are any problems such as damage or omission, the customer will reject it and it will become a problem item. Sometimes these problems may have occurred at the previous transfer station or even earlier, but they were not discovered or were discovered but continued to transfer irresponsibly. If it is discovered by the customer when signing for receipt, the courier station responsible for delivery will spend a lot of time and energy to deal with it even if it does not compensate. Therefore, many couriers will require a signature first so that even if there is any damage, they can say that they have signed for the delivery. If there are any problems, they can contact the shipper and it has nothing to do with them.

I suggest that when signing for express delivery in the future, if the courier refuses to inspect the goods first, you can first call the seller to explain the situation and agree to receive the goods first. If there is any unexpected situation, take photos in time to keep records as evidence. When signing for the goods, ask the courier if you can ask them to sign and then inspect the goods on the spot (if that doesn't work, don't insist). First, make a rough estimate of the weight of the goods and the weight written on the express delivery note. When signing, make a note of the actual receipt. Several pieces of goods and the exact time of receipt. If there is any shortage after opening the box, immediately tell the courier and ask to replenish the missing goods on the express bill (applicable to the courier who agrees to wait to see the goods together) and immediately take photos and Seller contact instructions.
