Sending fba from uk to USA Amazon

First time sending to USA fba from uk

When I select ups partner carrier I received 2 templates to download

1) packing list

2) commercial invoice

There is no barcode or anything on the template for ups delivery driver to scan , is that ok?

Do they not need anything else. Do I just stick the excel sheet packing list on the box and will the driver know what to do?

normally the shipping label had barcodes on it for ups.

Thanks
