When entering the Netherlands from a non-EU country, you must declare several categories of items to ensure you comply with Dutch and EU customs laws. First, you must declare any cash or "liquid assets" (including traveler’s checks) totaling €10,000 or more. You also need to declare commercial goods or personal items that exceed a total value of €430 if you arrive by plane or ship. Specific restrictions apply to "excise goods": you can only bring in 200 cigarettes, 1 liter of spirits (over 22% alcohol), and 4 liters of still wine without paying duty; anything over these limits must be declared. Furthermore, the Netherlands has very strict rules regarding "protected species" (items made from ivory, coral, or certain skins) and cultural heritage items. Perhaps most importantly, you cannot bring in meat, dairy, or most plant products from outside the EU due to the risk of introducing diseases. If you are carrying prescription medications, you should declare them and have a "European Medical Certificate" or an official doctor's note to prove they are for personal use and contain no prohibited substances under the Opium Act.
