I'm a French resident.
In 2019 I bought online a $200 laptop coming from Hong-Kong. It was sold by the merchant without VAT and sent by DHL. I remember very well I had to pay around 55 euros in VAT + custom taxes on the DHL website in order to get my shipment delivered to me.
It seems I made the mistake to delete all my emails concerning this device. I have absolutely no proof anymore that I paid the VAT and other taxes. I don't even have the invoice from the merchant anymore.
Now the thing is, I'd like to travel outside EU with this device. So the question is: When reentering EU (France) do I risk paying VAT and import taxes a second time if I'm not able to prove that I already paid them?
I want to travel with 2 laptops in total and several other electronic devices but I'm worried they ask me to pay for things I already paid for…
