Taxes and cost to ship vehicle from USA to honing kong
The tax you will need to pay is at least the "First Registration Tax". To calculate it, please check http://www.td.gov.hk/en/public_services/licences_and_permits/vehicle_first_registration/guidelines_for_importation_and_registration_of_mot/
The shipping fee really depends on the shipping company you will use. I expect ~US$1000. Check some shipping companies and they may give you the quotations.
