Hi! I just happen to handle Customs Compliance for a very large well known world wide company.

The duty rate for a bicycle rack assuming it is an unassembled, wall mounted, steel rack used for the storage, security and/or repair of a bicycle is 3.9%.

Assuming that this rack is adjustable and can fit on the rear of Sedans, Hatchbacks, Mini-Vans and Sport Utility Vehicles the duty rate is 2.5%
