Box 36: Preference
This box contains information on the tariff treatment of the goods. Where its use is provided for in the matrix of Title I, section B, it must be used even when no tariff preferential treatment is requested. However, this box must not be used in the context of trade between parts of the customs territory of the Community in which the provisions of Directive 77/388/EEC are applicable and parts of that territory in which those provisions do not apply, or in the context of trade between the parts of that territory where those provisions do not apply. Enter the relevant Community code from Annex 38.
The Commission will publish at regular intervals in the C series of the Official Journal of the European Union the list of the combinations of codes usable together with examples and explanatory notes.
