If you ship it by courier it will cost me an extra day of work for the custom clearance here in the Netherlands, because the couriers do not use the Form-A to custom clear the lenses.
This means that I have to contact them and explain that they can’t charge any import tax and the have to use the Form-A. The only problem is that the shipment is already delivered here and I got the Form-A in the office. So as you can see that this will cost more time and money then you ship it by Panalpina.
