Standard Input-Output Norms require verification that imported laboratory glassware inputs are used in specified export products.

The text requires determination of the proportion of various inputs used or required in manufacture of resultant export products for laboratory equipment and glassware made of fused silica, quartz, or borosilicate. Applicants must ensure that imported goods correspond to those actually used in the export product, linking input classification and unit measures to an explicit use verification requirement.
