What it is
A customs guarantee (Zollbürgschaft) is the financial security you put in place under the Union Customs Code so that duties, import VAT and excise stay covered while your goods are moving, stored under a special procedure or deferred for payment. It can be a comprehensive guarantee covering several procedures, or an individual guarantee per operation, and it is the prerequisite for most of the simplifications customs authorities expect from a serious importer or exporter.
