What is the cost of a binding tariff ruling?

German customs charges no fee to apply for a vZTA, as the Customs Portal confirms. Additional costs may arise if the authority cannot classify the good from the product description alone and requires laboratory testing or external expert assessment. You typically pay these costs. For UK sellers applying for an Advance Tariff Ruling, the same principle applies: the initial review is free, but elaborate additional assessments may increase costs. Submit your product description and supporting documents as precisely as possible from the start to avoid extra review steps.
