Customs business refers to activities involving the preparation, filing, handling, or representation of customs transactions on behalf of importers or exporters. In U.S. trade, customs business can include classifying goods, preparing entry documents, submitting customs entries, paying duties and taxes, communicating with customs authorities, and advising on import compliance. Because these activities affect legal responsibility and duty payment, customs business is usually performed by a licensed customs broker or by the importer directly.
