<h1>Input-output norms require imported inputs to match declared manufacturing composition for export compliance.</h1> Input-Output norms set the required composition and proportional consumption of inputs for manufacturing Indigo Carmine (Food Blue 1), listing Indigo, Caustic Soda Flakes, and Sodium Acetate with specified proportions. The schedules mandate determination of allowable input proportions and impose on applicants a requirement that imported goods match the materials actually used in the declared export product, thereby making import authorisation conditional on compliance with the declared input mix.
