Tungsten filament exports require specified input-output ratios for tungsten wire, molybdenum wire, and tungsten rod.

Input-output norms for Tungsten Filament exports specify that Tungsten Wire (0.9 mm+ dia) is permitted at 1.12 kg per kg of exported filament (excluding mandrel weight); Molybdenum Wire (0.9 mm+ dia) at 0.85 kg/kg (excluding mandrel); and Tungsten Rod up to 33% of the number of filaments exported. Applicants must ensure imported inputs are those used or required in the export product and proportions are determinative for compliance.
