There are several things you should know before you try to import boots into the U.S.

The key to importing boots is proper classification according to their Harmonized Tariff Schedule (HS) codes. The HS Code for a product determines its duty rate, applicable free trade agreements, regulations, and more.

Classification of footwear depends on many factors with the construction and type of use: To help your broker determine the correct HTS for your boot you should fill out a footwear form which will give the broker the information they will need to classify the boot.

Using the footwear form can also help you determine the correct HTS yourself if you know how to navigate the tariff.

In addition to general and special duties, there are two fees that apply to all shipments entering US domestic ports: the Harbor Maintenance Fee (HMF) and Merchandise Processing Fee (MPF). 

It's also important to establish the legality of the material(s) the boots are made of. Under the Federal Endangered Species Act, the selling of the hide, dead body, or product thereof, of protected animals is illegal. Additionally, some individual states have their own laws about which kinds of animal products they allow to be imported. If your boots are made of leather or something similar, you’re generally in the clear. However, if the material is more exotic (like snakeskin or alligator), make sure to check the origin of the material to ensure no protected animals were harmed during its manufacture.
