<h1>Standard Input-Output Norms require importers to strictly match imported inputs to declared export product uses.</h1> Standard Input-Output Norms specify the component items and per-unit proportions for manufacture of Gumboro D-78(1 ML), with the SION suspended. The norms require determination of allowable proportions of inputs for the resultant product and impose on applicants the obligation that goods sought for import and actually imported are those used or required in the declared export product.
