I switched to Aisler who are in Germany. They're certainly more expensive than China but still way less than quick turn options in the US. There will still be tariffs but they won't be nearly as high. There are also smaller PCB vendors in China other than the "big two" of JLCPCB and PCBWay that are willing to be a bit more flexible and not charge the max possible duty upfront via DDP incoterms.
