Best answer , as your code authorities . But for where I live we have to use the plastic pipe that's rated for underground gas lines.

If you mean the yellow plastic coated stainless convoluted pipe, then no, that wouldn't be appropriate buried underground or for exterior use for that matter.
The gas company uses a yellow plastic pipe specifically designed and qualified for direct burial for direct burial. Sleeving a gas pipe is a bad idea because, in the event of a leak, the sleeve becomes a potentially deadly explosive chamber.

I was out looking for supplies yesterday and it appears my local HD only has black pipe and that home flex csst ****. After a little research you can run the home-flex underground but it needs to be sleeved so after the last comment it is out. Plus its expensive at like $2.25 a foot. So i need to find somewhere that sells the yellow gas pipe.
My plan is to run 4 new lines total from my house
1 1" PVC conduit as a sleeve for PEX for water
1 1 1/2" conduit for a new electric service (currently runs overhead)
1 2" conduit for misc low voltage stuff cameras network tv
1 gas line

You should call your local gas utility for requirements and as a possible source for the materials.
The yellow gas pipe (PE or polyethylene) is used for the underground portion of the line, but must be connected to a steel riser at both the garage and house end. The yellow pipe is dirt cheap, but the risers are fairly costly. Depending on the jurisdiction, the PE pipe may be connected to the steel risers using various fitting---most of which are fairly expensive either for the part and/or the tool need to install them.
When you use PE pipe, you need to bury a copper tracer wire along with the pipe so that it can be located at a later date.
In my city (Indianapolis Indiana) the gas utility is (or was the last time I needed something) about the cheapest source of materials. There are generally a few utility employees that have side businesses of installing gas lines for situations like yours.

National fuel sleeves black pipe entry lines here all the time. There is really no more explosion hazard from poly leaking inside a black pipe than there is from a leak in plain black pipe.
