In case you want to purchase and import a Single Board Computer, you should know that the correct tariff / TARIC code is as follows:
SBC (Single Board Computer): 8471.41.00 00
The extra two zeroes are normally not needed, and will usually be added automatically.
There are at least other two tariff / TARIC codes that seem to 'cover' SBCs, but they're incorrect and may cause you to pay more for the item in the end.
It's on purpose that I do not mention the incorrect codes, in order to avoid people making mistakes about it.
Advice: It's a very good idea to familiarize yourself with the import fees, duties and taxes before you place an order, and expect to pay more than you've calculated. In some countries there is a lower limit, which means items below that price are not subject to fees, duties or taxes.
