Phosphor Bronze Wire: prescribed input ratios for copper and tin and requirement that imported inputs match export use.

Standard FTP input output norms for Phosphor Bronze Wire (Tin Bronze Core Wire) set copper input ratios (1.05 kg/kg content or 1.075 kg/kg content depending on input form) and tin ingot ratio (1.05 kg/kg content); the SION is suspended and applicants must ensure imported inputs are those actually used or required in the export product, with determination of permissible input proportions for manufacture.
