Standard Input-Output Norms govern paracetamol manufacture under PNCB route, requiring specified input proportions and import-use consistency.

Standard Input-Output Norms prescribe fixed input proportions for manufacture of paracetamol via the PNCB route, specifying required quantities of Para Nitro chloro benzene and Acetic Anhydride for production of paracetamol, and require determination and verification of input proportions so applicants must ensure imported goods match those actually used or required in the export product.
