Boxes/Cartons input-output norms set component ratios and require imported inputs be used in corresponding export products. Standard Input-Output Norms specify allowable materials and numeric usage ratios for boxes/cartons exported under the FTP (kraft/paper board, metalised polyester, corrugated board, liners, parchment, polyester film, aluminium liner, polyolefin granules, varnish, and printing ink with 1% FOB valuation). A substituted Public Notice altered the kraft/paper-board content ratio. Applicants must ensure imported inputs are those used or required in the export product and that proportions conform to the prescribed norms.
