What if my last departure point from the EU is through (transit) flight via another EU country?

Hand baggage: Goods carried as hand baggage and tax-free forms must be produced to Customs at the final transfer, the last point of departure before you leave the EU. Hold baggage: If you are leaving from one EU airport but changing flights (in transit) at another EU airport and the goods you are exporting are checked through to your final destination outside the EU, go to Customs in the country where you check in your bags; your tax-free form will be export-validated as if that were your last EU departure point. If you collect your bags in between transit, then you must go to Customs at your last point of departure in the EU, where you finally check in your bags.
