Input output norms for zipper sliders require pro rata input adjustments and strict verification of imported inputs used in exports.

Standard input-output norms list specific inputs and quantities for Zipper Sliders made of zinc alloy, note the norm's suspension by Public Notice, and require pro rata recalculation of input requirements if export product weight changes; applicants must ensure imported goods correspond to and are actually used in the declared export product, and the proportion of inputs must be determined where multiple resultant products exist.
