No comments suggests that Longpete already answered the question in his post just above, right?
If you are no longer in the 1 year moving home grace period ---- You have a personal allowance of 430 euros each trip when arriving in France by boat or plane. There is then no need for an inventory and you should feel safe to drive straight through. (Not sure about Eurotunnel, I suspect the allowance is the lower one as if driving from e.g. Spain).
Otherwise I would strongly recommend the simple process below… Keep it all under 1000 euros fire sale value, ie still itemise things with value on an inventory, and calculate the weight if heavy to ensure the total is less than 1000kg in weight and size. You can then make a verbal declaration to the Douanes. They may well then let you go without charges since it’s a lot of paperwork for them, particularly if you make clear they are personal items, not for sale. I have done this a couple of times via Dieppe, middle of the night.
From the Q&A on the douanes website (https://www.douane.gouv.fr/sites/default/files/2021-12/27/Questions-Reponses-Dispositif-ATVAI-2022-Operateurs.pdf) it states: “In accordance with article 135(1)(b) of delegated regulation 2015/2446 of the Code of Union customs, goods of a commercial nature, provided that they do not exceed the threshold of 1000 euros in value or 1000 kg in net mass, may be declared verbally for release into free circulation. In this case, the services customs officials recover, where applicable, duties and taxes by means of a receipt (known as “receipt 155”).”
Excellent reply. Thanks.
