The craft insurance policy I have limits USA sales to 20% of total sales (to a max of £10,000). I asked what happens if my very first sale is to the USA (which would make the total 100%) and the answer was they look at the overall sales over a 12 month period.

But I can’t know in advance what my total sales to the USA will be. What if 6 months down the line every sale is still only to customers in the USA?
Is there anyone here selling to the USA from the UK? If so, what kind of insurance do you have?

Thanks in advance.
