This is now a reasonable concern for any US company selling Chinese products. I recently read an article in Inc. magazine about a company that is the US importer of Chinese replacement tires. They are a small importer and cannot possibly check each batch of tires that are shipped. Apparently, the manufacturer started to cut some corners and the tires started failing. By the time the US importer realized he had an "issue" a couple of people died in accidents caused by the tire failure. Naturally, the Chinese manufacturer denies any responsibility or accepts any fault. The importer is between a rock and a hard place.
