N.C. Gen. Stat. § 105-449.66
An applicant for a license as an importer must indicate on the application the type of importer license sought. The types of importers are bonded importer, occasional importer, and tank wagon importer.
A person may not be licensed as more than one type of importer. A bulk end-user that imports motor fuel from a terminal of a supplier that is not an elective or a permissive supplier must be licensed as a bonded importer. A bulk end-user that imports motor fuel from a bulk plant and is not required to be licensed as a bonded importer must be licensed as an occasional importer. A bulk end-user that imports motor fuel only from a terminal of an elective or a permissive supplier is not required to be licensed as an importer.
