Verification of origin certificates: importing authorities may seek additional information and demand guarantees to protect fiscal interests. Importing authorities, upon reasonable doubt as to an origin certificate's authenticity or data veracity, may request additional information from exporting authorities limited to government-held registers and issuer documents; consultations must state clear reasons and be handled by designated offices. Importation operations shall not be suspended, but authorities may demand a guarantee to protect fiscal interests, with the guarantee capped at the customs duty value applicable if the product were imported from third countries under the importing country's law.
