The US security filing is the importer’s, and it has to exist before loading.
Ocean cargo bound for the United States needs an Importer Security Filing, the ISF or 10+2. US Customs and Border Protection requires it no later than 24 hours before the cargo is loaded onto the vessel destined for the US. Yihang prepares the China export on its AEO file so that filing can be made. Yihang is not the US importer, and does not become one by booking the box. The quote names who files the ISF.
