By primary stage of production we refer to the harvesting or collection of fibre (the cotton harvest; wool and rawhide husbandry, shearing etc); crude oil production (extraction, refining) for synthetic fibres, plastics and similar; and mining for metals and gems.
The second stage of production includes textile production (ginning, spinning, knitting, dyeing, embroidery), leather tanning, plastic processing, and moulding.
The final stage of production considers the assembly of the final product (the facilities responsible for cut, make, and trim).
