Not if they're knowingly holding and shipping inventory of hazardous materials, which is the point of "Fulfilled by Amazon." I mean, how do they sell something without knowing what it is? If they're selling chemicals without a single person checking to make sure that they're properly handled then that's even worse. Obviously, the person who sent them the sulfuric acid is at fault to, but there were several failures here.
