<h1>Cast alloy permanent magnets: prescribed input proportions per kg and requirement that imported inputs match those used in exports.</h1> Standard Input-Output norms for cast alloy permanent magnets set per kg input proportions (aluminium ingot 0.112 kg; Armco iron 0.714 kg; cobalt 0.336 kg; copper 0.042 kg; nickel 0.196 kg) and note that magnets are normally de magnetised during transport. The norm is suspended by public notice, and applicants must ensure imported inputs correspond to those used in the exported product for export compliance and input use verification.
