<h1>Input-output norms require imported components to match actual use in exported audio magnetic head manufacture for compliance.</h1> Standard input-output norms set allowable components, alternate materials, unit measures and quantities for manufacture of Audio Magnetic Heads (R.P. Mono Head). Applicants must determine and document the proportion of inputs used for each resultant product and ensure imported goods correspond to those actually used or required in the export product, as a condition of compliance with the Foreign Trade Policy.
