Hello Ralph,
Thank you for your message and explanations, they are very helpful and make me understand more about the situation.

I'm thinking exactly the same as you, and now I'm just waiting for the French postal service to reach an agreement with the CPSC regulator. I think it will takes several weeks to get it done.

I can check what DHL or Fedex are offering, but their price for shipping to the US is not the same as I was able to offer.
At the moment price for small parcels are about 20€, medium 30€ and big 40€ (more or less), and I wont be surprised if the prices for the same stuff will double or triple.
And honestly only a couple of customers would be interested to have my products at this price... It's sad to pay 50€ worth of shipping for a 5€ product.

Well I'll be patient and I'm lucky having non US modellers ordering some of my products !

Thanks again Ralph
Ben
