Manufacturing accounting is not a topic in the syllabus for Paper FA.
However the market value is of no relevance whatsoever except in the case of inventory held at the end of the accounting period which is valued at the lower of the cost of manufacturing and the net realisable value. This is all explained in my free lectures on the valuation of inventories.
The lectures are a complete free course for Paper FA and cover everything needed to be able to pass the exam well.
