Standard Input-Output norms for iron castings require imported inputs to match specified proportions actually used in manufacture.

Standard Input-Output norms prescribe permitted raw material inputs and quantities per 1000 kgs of Industrial/Sanitary Iron Castings (Blast Furnace Route), list alternatives and ash-content thresholds, and state the entry is suspended; applicants must determine input proportions used in manufacture and ensure imported goods correspond to those used or required in the export product.
