What is the code used for?

3923 10 90 10 is a TARIC code, the most detailed, ten-digit level of the EU customs tariff. Its first eight digits, 3923 10 90, are the CN code and the first six, 3923 10, the HS subheading.

The code is the lowest level of the nomenclature and is used as it is: an import declaration takes all ten digits (3923 10 90 10), an export declaration only the first eight (3923 10 90).

Duties, VAT, import restrictions and the other measures that apply to the code are in the EU's TARIC service. The search is a guide only; Finnish Customs gives binding decisions on classification (Binding Tariff Information).
