After you accept the offer for shipping, you know also to which airport we will ship. On that moment you can start looking for for a broker.

When selecting a broker, be sure to read the fine print about what fees they do and what they do not cover.
You will also want to have the broker use CBP code HS8712.00.5000, the code specific to non-eBike velomobiles. This code will get you the lowest import duty fees. Fees include: Entry fee (fee paid for the broker services) $125-160, single entry bond $50-60, courier fee (if you have the broker pay airport terminal fees), customs duty 3.7% of purchase price, merchandise processing fee, and airline terminal fee $60-120. Your broker will also need power of attorney for the shipment. If picking up from the airport, some fees can be paid directly to the airport at pickup avoiding a handling fee from the broker. We will provide you with an Airbill (essentially the plane ticket for the shipment).
