Can you split the tablet in half for a smaller dose?

The tablet is quite small and not scored to be cut so you might have trouble getting a very accurate split, but it could be done.

It says packaged and tested in the USA, but what is the country of origin?

As marked on the label on the bottle: "Carefully manufactured by Carlyle Nutritionals LLC, Melville, NY 11747 USA." : )

This is not slow or sustained release, correct?

Does not seem to be a sustained release, but works nicely.

Is this melatonin USP verified?

I don’t know if it’s verified but in my opinion didn’t work well. I’ve had much better results With Sundown Brand. You can’t find the Sundown 300 mcg right now. Their liquid version does the trick though.
