Is it incorrect to say " I am calling in regards to your shipment to Shanghai"?

In my opinion, it's simpler and clearer to say

"I am calling about your shipment to Shanghai".

Best wishes, Clive
It think it is fine. I would say, "I'm calling regarding...."

"in regards to" sounds wrong to me. I know people do use it, but I've always thought of it as a mistake. http://wsu.edu/~brians/errors/regards.html calls it "nonstandard". I guess people differ in their usage...

The correct usage is, "in regard to."
