Effective December 18th 2025, all shipments to USA addresses are subject to a base 10% Tariff. Fortunately any Tubes made in the USA or Canada are exempt under the CUSMA Rules. 

If you order a non exempt product the Store will automatically charge the base 10% Tariff rate, but in many cases the final Tariff will be lower and if that’s the case we’ll promptly refund the difference.  NOTE, in some cases the Tariff rate will be higher, in which case we’ll contact you and if agreed, send you an Invoice for the difference.

Note we will not refund or charge for a Tariff difference of $10 or less.

You can verify if a product is exempt, just by looking at the first line of each listing which will say “USA Tariff Exempt”.
