Standard Input Output Norms limit allowable inputs for printed stationery exports and set declaration and mixed consignment rules. Standard Input Output Norms prescribe allowed inputs and quantitative usage norms for exported ruled and unruled printed stationery, listing writing/printing paper, printing ink, graphic art film, binding materials, PVC/BOPP film, paper board and plasticiser paper with specified per unit or percentage allowances. Exporters must declare actual coated and uncoated paper quantities in shipping bills or ARE 2 to claim entitlements; mixed consignments face a capped entitlement for coated paper with the remainder as uncoated imports. Imports of items 4-7 are not permitted against exports of ruled sheets. Applicants must ensure imported inputs are those used in the export product.
