I have been through chelation therapy, avoiding heavy metals, however inconvenient it may seem sometimes, is DEFINITELY easier than going through the treatment to remove them!
It’s getting harder and harder to avoid things made in China. I have a small sewing shop and it can be darn near impossible sometimes to find affordable fabrics woven in the USA.
Except for drill and a few other fabric types, clothes made in China are not made with material made in China. Most of the material for clothes is imported from other countries.
What would be a real source of concern would be food products made in China.
Just as was happening in the U.S. back in the 80's, tanker trucks that were delivering liquid food products to U.S. food processing factories had carried an industrial chemical on their prior haul. Washing out the truck did not get all the chemical containment. China still has not dealt with that issue.
