A written decision specifying the correct tariff code for one freely declared good. It is valid for 6 years from the date of its issuance (except when regulations are changed, interpretations of regulations or errors in the decision are shown). It is issued at the written request of the person concerned. In the event that it becomes invalid due to a change in the World Customs Organization’s interpretation of the regulations, or was issued due to an error or is contrary to law, the person to whom this information was provided may still use it for a period of 6 months from the date of publication of the changes or from the notification, if he has concluded binding purchase or sale contracts on the basis of the BTI, before the date of publication or notification. Binding tariff information is invalid if it was issued on the basis of false documents or incorrect or incomplete data submitted by the applicant.
