It doesn't matter at all. China Dupont paint is just a fake copy of DuPont.

this enterprise can't be found on Jiangmen industrial and commercial hongdun.

"American DuPont paint" is fake. Dupont did not set up a factory in China at all, nor was it authorized. It is pure paint produced by "Guangdong Jiangmen Dupont Coatings Co., Ltd." and a fake of "buying dog meat with sheep's head hanging". Dupont is a big company in America, but it has nothing to do with "Guangdong Jiangmen Dupont Coatings Company".
