Of the four major manufacturers, only USG had impact resistance on their web site -- the other three talked about the recycled content of their products. Doesn't it seem to you that if a product is claiming a differentiator -- the impact resistance -- that they would actually put that in the product literature? Is anyone else tired of all the green information, and none of the performance information?

I can find ASTM C 1629 information for most of the major manufacturers I'm aware of, all on their websites. This will show soft body impact and hard body impact resistance. Is there something different you are looking for? But yes, I'm also tired of all the green info and none of the performance info. I don't think the recycled content of the paper facing on your gyp board is going to get me to that next point threshold for LEED. But thanks for trying to sell me a product based on that.

Few of the manufacturers' products have cross-equivalents with anyone else's product, meaning that if you want a particular performance level with two or more of the characteristics in C1629, you may find only one manufacturer that meets both. This post may not make sense unless you really read C1629 carefully.
