You can check the TARIC database to get the EC duties on any good imported into the European Community: http://ec.europa.eu/taxation_customs/dds2/taric/taric_consultation.jsp?Lang=en

But keep in mind that 2 customs agents might put an ASIC in 2 different categories. So maybe they ask you XX% the first time you import an ASIC and YY% the second time... I advise you to find a cheap category (with 0% duties) and ask your supplier to indicate this TARIC code when he exports.
