The Supreme Court examined whether polymer chips, used in the manufacture of nylon yarn, can be classified under Item 15A of the Central Excises and Salt Act, 1944, for excise duty purposes during the period 1962-1972. The Court held that these polymer chips, produced from caprolactam monomer, do not fall under the definition of 'plastics' as per the relevant entry, thus exempting them from excise duty. The judgment clarified the classification criteria for intermediate products in the context of excise duty.
