XINU 80647 45G 1 What does it mean on the container? What does it mean to have a 5 and then a frame? I hope you can answer as soon as possible. I study trade.

As for the landlord's "80647", there should be one missing, and it should be six. This is the serial number of the container.

The "5" with an outer frame behind the six digits is the check code of the box, which is determined by the four-digit box east code and the six-digit serial number.

45G 1, 45 represents the overall dimensions of the box, that is, 40' long, 9'6' high and 8'' wide, and G 1 represents the dry goods box.
