If the chip label is made on a large format vinyl printer, a lot of them pre-heat the material as it goes through and as it cools it shrinks a little bit. That may be why your noticing the vinyl as being a little smaller. This is only assuming it's being done on a vinyl printer like a mimaki or something.

If you want the vinyl labels, maybe ask them to increase the size of the template of your chip by a tenth of an inch and see if that will bring it closer to an inch when it's done with the print.
