<h1>Input-output norms require imported components to match declared use in export manufacturing under FTP policy.</h1> Standard input-output norms prescribe component types and proportional content for manufacture of fibreglass/synthetic filter bags with stainless steel fittings, listing permissible inputs (filter cloth, sewing thread, stainless steel strip AISI 301) expressed as unit or weight content per export product. The schedules require determination of input proportions and obligate applicants to ensure imported goods are those actually used or required in the export product.
