If people are upset by so called "dumping" - can't they just let China charge more than they would have for this aluminum?<p>Aluminum has well known fixed costs in smelters, it's one of those products they use as an example where it may make economic sense to keep a smelter going (even if incurring losses / ) because the cost of shutdown.<p>Ie, a potline may take up to a week just to "turn off" and a huge amount of effort - think a month of full time work + weeks of troubleshooting as annode effect issues, alumina concentration and other bits settle down. Don't you basically have to recondition (fully, replace all anodes, dig out the crust) the pots, and even then you may be taking a bit hit on pot life with the cool down / reheat cycle?<p>I know the US has "anti dumping" rules regarding sugar as well - which I've been told contributes to a fair bit of corn syrup use.<p>I'm not that hung-up on the US blocking imports of cheap materials (if that's what the US wants to do), but how does the US get some third party country to grab this quantity of metal? Ie, China could sell to other countries that are not as concerned about dumping. For example, why would a poor country without a local smelter even care about "dumping" - it would seem the cheap prices would be a subsidy in effect.
