(d) Assembling Industry which assembles different component parts to make a new product, as in the case of television, car, computer, etc.

(i) Analytical Industry :
which analyses and separates different elements from the same materials, as in the case of oil refinery.
(ii) Synthetic Industry :
which combines various ingredients into a new product, as in the case of cement.
(iii) Processing Industry :
which involves successive stages for manufacturing finished products, as in the case of sugar and paper.
