The Imperial Office of Customs, often shortened to Imperial Customs, functioned as a branch within the Commission for the Preservation of the New Order. This division was responsible for guaranteeing that all businesses involved in import and export activities adhered strictly to the legal framework and guidelines established by the Galactic Empire. To enforce these regulations, their officers frequently employed TIE Boarding Crafts for transportation to freighters, where they conducted cargo inspections and upheld their mandated power. Nien Nunb, a Sullustan who previously engaged in smuggler activities, frequently encountered Imperial Customs personnel after being intercepted by Star Destroyers. The exact connection between this office and the organization known as Imperial Boarding Inspection and Customs remains unclear.
