Each country of origin of manufacturing has different Tariff rate. For example. U.K origin will pay 10%. Please find out this rate yourself. Shipping to non-U.S. is tariff free. You do not pay anything. 
Most of my tubes were U.S. made. So, you are free of tariff if shipping to U.S. Thanks for the attention.
Due to the new 35% U.S. Tariff on all items shipped to the USA, Buyer will pay for this new burden. My prices have been lowered to the minimum, and cannot be jeopardized by this new tariff, hope buyers will understand, thank you.
