Member States may create, as a national component, a national binding tariff information system (‘national BTI system’) together with a national trader portal.

The EBTI system shall be used to support the monitoring by the customs authorities of the compliance with the obligations resulting from the BTI in accordance with Article 21(3) of Implementing Regulation (EU) 2015/2447.

The EBTI system shall be used by the Commission to inform the Member States, pursuant to the third subparagraph of Article 22(2) of Implementing Regulation (EU) 2015/2447, as soon as the quantities of goods that may be cleared during a period of extended use have been reached.

The authentication and access verification of economic operators and other persons for the purposes of access to the common components of the EBTI system shall be effected using the UUM&DS system referred to in Article 14.

For customs representatives to be authenticated and be able to access the common components of the EBTI system, their empowerment to act in that capacity must be registered in the UUM&DS system or in an identity and access management system set up by a Member State pursuant to Article 18.

The authentication and access verification of Member States' officials for the purposes of access to the common components of the EBTI system shall be effected using the network services provided by the Commission.

The authentication and access verification of Commission's staff for the purposes of access to the common components of the EBTI system shall be effected using the UUM&DS system or the network services provided by the Commission.

The EU trader portal shall be an entry point to the EBTI system for economic operators and other persons.

The EU trader portal shall interoperate with the central EBTI system and offer redirection to national trader portals where national BTI systems have been created by Member States.

The EU trader portal shall be used for submitting and exchanging information pertaining to applications and decisions related to BTI or to any subsequent event which may affect the original application or decision.

The central EBTI system shall be used by the customs authorities to process, exchange and store information pertaining to applications and decisions related to BTI or to any subsequent event which may affect the original application or decision for the purposes of verifying whether the conditions for the acceptance of an application, and for taking a decision, are fulfilled.

The central EBTI system shall be used by the customs authorities for the purposes of Article 16(4), Article 17 and Article 21(2)(b) and (5) of Implementing Regulation (EU) 2015/2447.

The central EBTI system shall interoperate with the EU trader portal, and with the national BTI systems, where created.

Where a Member State has created a national BTI system in accordance with Article 19(3), the national trader portal shall be the main entry point to the national BTI system for economic operators and other persons.

Economic operators and other persons shall use the national trader portal, where created, with respect to applications and decisions related to BTI or to any subsequent event which may affect the original application or decision.

The national trader portal shall interoperate with the national BTI system, where created.

The national trader portal shall facilitate processes equivalent to those facilitated by the EU trader portal.

Where a Member State creates a national trader portal, it shall inform the Commission thereof. The Commission shall ensure that the national trader portal can be accessed directly from the EU trader portal.

A national BTI system, where created, shall be used by the customs authority of the Member State which created it to process, exchange and store information pertaining to applications and decisions related to BTI or to any subsequent event which may affect the original application or decision, for the purposes of verifying whether the conditions for the acceptance of an application or for taking a decision are fulfilled.

The customs authority of a Member State shall use its national BTI system for the purposes of Article 16(4), Article 17 and Article 21(2)(b) and (5) of Implementing Regulation (EU) 2015/2447, unless it uses the central EBTI system for those purposes.

The national BTI system shall interoperate with the national trader portal and with the central EBTI system.
