<h1>Standard input-output norms require imported components to match those used in exported dot matrix printers.</h1> Standard Input-Output norms for dot matrix printers prescribe an itemised list of permissible components with unit allowances and an engineering plastics tolerance; the SION entry is suspended by Public Notice No. 03/2024-25. Applicants must ensure imported items match the specified components and that the proportions of inputs used in manufacture correspond to the declared exported product, with compliance judged by actual use of the imported goods in the export product.
