When entering the Netherlands, you must adhere to both EU-wide and Dutch-specific customs regulations. You are strictly prohibited from bringing in meat, milk, or dairy products from non-EU countries due to the risk of introducing animal diseases. Endangered species (protected under CITES), including certain ivory items, coral, or skins, are banned. While the Netherlands is known for its "coffeeshop" culture, it is strictly illegal to bring any form of cannabis or other narcotics into the country across the border. Weapons such as knives with multiple cutting edges, flick-knives, and pepper spray are also illegal to possess or import. If you are bringing more than €10,000 in cash, you must declare it to customs. Additionally, be careful with "look-alike" or counterfeit goods; while small amounts for personal use are often overlooked, importing large quantities of fake designer items is a crime. Finally, certain plants and soil from outside Europe are restricted to prevent the spread of agricultural pests, so always check the NVWA (Netherlands Food and Consumer Product Safety Authority) website if you plan to bring flora.
