From back when I was working in that industry, I was told we couldn't really compete on price with China. They were trying to get glass from China because it was cheaper than what we could make in our own float plants. We were trying to compete on quality, that is to say, delivering less broken or damaged glass. That said, you're right--I don't remember too much trouble shipping raw glass. It was just coated in Lucite and the first sheet is always a write-off. We had more trouble when people had packs fall when trying to load them into the gantry every so often, though broken sheets were quite a pain to deal with sometimes more from a safety perspective, when the crane can't get suction on it to drop it and it's too big to safely handle.
