Hi, I've just got my first online order from the U.S which is exciting. BUT I need help with customs requirements. The order is small (way under the import threshold). 1. How do I find the correct customs number to put in the Royal Mail International Tracked shipping order (it's beauty products - a cleanser) 2. Do I need a separate form to fill in and if so where do I get this? Any help most appreciated. Have been searching for a while but finding HMRC less than easy to navigate.
