Again, that depends on the maker. The info said it's using Alpha pots which are decent, and polypropylene caps really aren't that much cost... a few pennys, which shouldn't be an issue on a guitar in that price range.
It appears that they aren't using the generic ceramic humbuckers that most Chinese manufacturers install. They're Alnico pickups. I'll bet they will be similar to what GFS sells for <$40 each.
