You will find information about current regulations concerning duty-free allowances/value limits on the customs website:
If you exceed the value limits, you must pay additional import duties calculated on the full value of an indivisible product (e.g. jewellery, clothing, electronics). In this case, take the exit marked in red when you go through customs and declare the products.
Note that goods for commercial trade and goods subject to prohibitions and restrictions must always be reported.
Special regulations aimed at preventing the spread of epizootics apply to the import of meat, milk and meat and dairy products. In your own interest, be sure to review the applicable import regulations before starting your journey.
