Customs declaration on moving to France

I’ve just bought a house in France and intend to move out here permanently (I’m a dual UK/French national). I came over to complete the purchase and brought a car load of tools etc for work I knew I would have to do while I was here. When I went through French passport control (with my French passport in an English car) she asked me if I’d done a customs declaration. I said I hadn’t and she told me off then let me through.
So my question is: what is the procedure when moving to France? I’ve got a ton more stuff to bring down and she’s made me nervous.

This is the procedure and the forms. (I’ve given it to you in English despite you saying you are dual national as not automatic that you would speak French - I’m also German and my German is that of a 7 year old child).

Good call - one of my lifetime regrets is that I’m a Frenchman who barely speaks French. Thank you so much for the help.
