I ship from Canada to the United States and am wondering if Amazon will inform buyers of potential tariffs when they buy my items?

I'm worried I could get negative feedback or claims from buyers being charged tariffs upon delivery.

Or will Amazon charge the tariffs to the buyer when they pay?

Q about tariffs: do they apply to any product that's made in China or just to ones you are importing? Say you are buying a product that says Made in China from a US based wholesaler, distributor or store, but you have not imported it from China yourself. Is this subject to tariffs when it's eventually sold and/or does it depend on the category of product?

With the new Trump tariffs of 25% on all imports to USA, is Amazon informing buyers in advance that their purchases from Canadian-based sellers will be subject to these tariffs? Do I need to worry about customers coming at me angrily with unexpected charges? I've turned off all my listings (vacation) b/c of all the uncertainty, and even with the confirmation of these tariffs, I want to know what Amazon is doing to mitigate customer frustration in the face of these, but there has been zero communication on this from them at all. Seriously disappointing.
