costs with the new world order

As a good part of the tools and materials we use in this trade of ours come from foreign parts now i:e BM,PURDY,Zinsser that's without euro problems where do you see prices and supply problems going
Will imports be sat at the docks awaiting clearance ? Will prices go through the roof as the pound fluctuates ?
or will we all rush back to Duluk and Hamiltons etc ?
