Input-output norms define permissible fabric and reflective-band use for industrial workwear, conditioning imports on actual user requirements. Standard input-output norms specify allowable per-piece consumption of high-visibility polyester/cotton blended or polyester dyed fabric and reflective bands for listed industrial workwear items; import of reflective band is subject to actual user condition. Schedules determine proportions of inputs usable in manufacture, and applicants must ensure imported goods are those used or required in the export product and that actual imports match declared usage.
