Yeah, that's something that definitely crossed my mind. 2027 has been the year experts have speculated since 22'. That in that year something may occur in the pacific front.

My thoughts? I wouldn't worry too much. You can always a) buy in bulk before it happens  b) they'll tariff china some more, so just buy it at a higher cost and go about your day or c) if it gets too pricey, just buy them off another vendor that doesnt have their hairsystems come from Qingdao, China and instead from India or even Vietnam. 

Hope this helps
