Where a consignment is made up of goods falling within different tariff subheadings, and dealing with each of those goods in accordance with its tariff subheadings for the purpose of drawing-up the customs declaration would entail a burden of work and expense disproportionate to the import duties chargeable, the customs authorities may, at the request of the declarant, agree that import duties be charged on the whole consignment on the basis of the tariff subheadings of the goods which are subject to the highest rate of import or export duty.
The Commission may, in accordance with the regulatory procedure referred to in Article 184(2), adopt measures for the implementation of this Article.
