it is a company that imports your products into us, you need to have one in order to clear customs, probably he is asking either to know the custom brokers adress to ship the product or to offer you the full service door to door, i would recommend the second one!

because usually they would be able to handle that for you, they’re probably just asking if you have your own customs broker, if not you can get the shipping company to do it for you they charge a small fee.

how much is the small fee normally ? my supplier told me $80 per order

Air express you don’t need a customs broker, that is handled by the carrier
