Points for Attention

For bringing item into Germany from European Union countries, there shouldn't be a problem as long as it is portable, for personal use and it conforms to tax exemption policy. For goods from non-EU countries into Germany, as long as the value is not more than 175 euros, it is free of tariffs. But the policy is limited in certain items, such as tobacco, alcohol, and perfume.

Visitors from outside the EU countries at most shops in Germany can enjoy VAT free shopping. You can get the 19% consumption tax reimbursement from the purchase price. After shopping at the duty-free shop, keep the receipt. Before departure, please go to the tax rebate window, there you can get cash back.
