+These fees are valid from October~1, 2021. German customers pay VAT with the bill.
+Customers outside Germany pay VAT reverse charge. In exceptional cases, when the 
+actual working time on a unit under test exceeds \SI{25}{\percent} of the 
+average working time, the actual costs have to be charged. Other additional 
+costs may result from expenditures of PTB for unusual special gases, special 
+services, transportation, customs, or other duties.
