<h1>Input-output norms: imported insulation tubing must match materials actually used in the export product under FTP compliance.</h1> Standard Input-Output Norms under the Foreign Trade Policy govern permissible use of heat shrinkable insulation tubing for sleeve conductors, identify product descriptors and unit measures, note an administrative suspension of the item listing, require determination of input proportions for resultant products, and obligate applicants to ensure imported goods are those actually used or required in the export product.
