The only legal requirements to opening an import business are having an importer of record number, which is usually just the business`s tax-identification number, and a surety bond to protect the U.S. government if you can`t pay your duties, taxes and other fees. Surety bonds are required for all entries where the shipment is valued at more than $2,000, but are used on smaller shipments also. They can be purchased through a surety company or a customs broker. There are single-entry bonds that cover one entry. Unless you intend to only import once or twice a year I would recommend that you buy a continuous bond. Continuous bonds cover all your import shipments for a year or longer.
