Input-output norms set component allowances for single-phase shell motors under SKD, requiring imported parts be used in exported products. Suspension of the SION for single phase shell construction motors under SKD condition lists specified engineering inputs and the permissible input quantities or units for manufacture of the export product, including materials alternatives and FOB-linked allowances for composite insulation. Applicants must ensure imported goods match the listed inputs and quantities and are actually used or required in the exported motors; proportions of inputs for different resultant products are to be determined and applied per the SION schedule for export compliance.
