Input output norms dictate permitted input proportions and require verification that imports are used in the declared export product.

Standard input output norms for brazed wheelchair components specify constituent inputs - steel tube/section/profile, brazing wire and brazing flux - and their per unit proportions for establishing admissible import content for export manufacture. Applicants must ensure that imported goods correspond to the inputs required or used in the declared export product; authorities determine and enforce allowable input proportions and may require documentation proving consumption in the export product. The schedule entry is recorded as suspended by public notice.
