You're mentioning the largest American Brands, which do not represent the bulk of businesses. In fact they have different channels to setup their businesses and lobby their way around. When I made that comment I was referring to SME, which is also the bulk of let's say, Chinese sellers on Amazon US. Try to do what Chinese people do on Amazon, but on a Chinese platform as a SME, to sell products in China.
Your SME will be about as successful at operating in a Chinese market, as a Croatian SME will be successful at operating in an American market. That is to say, you'd need a pretty exceptional product, that is significantly better then local alternatives to get anywhere, because you're not going to be able to compete on price, or on brand recognition. The reason Chinese SMEs are punching above their weight in foreign…
Try buying something like a coil winder, an induction heater, a spot welder, or a heat sealer. Even in the US, you're much more likely to find Chinese equipment more competitive and more readily available. Especially for an SME.
