Mail parcels to the US from September 22: who actually files the new informal entry for a small seller?

that condition isnt new though is it.

looks like its been the rule for nonresident principals for decades, long before this mail thing.

so the hoop isnt the paperwork. its finding someone willing to stand in it.

you write entries. what would you want from a seller you have never met, before you agreed to be their agent for service?

Proof you can bind the company. Signed with me direct, not through your forwarder. Duties on deposit before I file. One lid, I decline.
