<h1>Input-output norms require imported inputs to match prescribed proportions and be actually used in the export product.</h1> Standard input-output norms prescribe permissible input proportions for manufacture of stainless steel variety 'x' via photo chemicals machining. Schedules determine proportions of various inputs for resultant products and list input and output weights. Applicants must ensure imported goods are those required or used in the declared export product and that actual imports correspond to the inputs claimed for manufacture.
