Standard Input-Output Norms define permissible inputs and verification obligations for forged alloy and stainless steel machined parts exports. Standard Input-Output Norms set permissible imports and input consumption for forged machined parts of alloy or stainless steel ( 90% by weight). They specify allowances for forging-quality alloy/stainless steel feedstock per kilogram of exported content, percentage allowances of FOB value for rust-preventing oils and primer paints, and percentage allowances of FOB value for miscellaneous manufacturing items. Applicants must ensure imported inputs are those used or required in the export product and authorities will determine and verify proportions of inputs used in manufacture.
