Silicon carbide briquettes: 1 kg requires 0.916 kg crude; imports must match declared export inputs for compliance. The input-output norm specifies that producing 1 kg of Silicon Carbide Briquettes (90% SiC) requires 0.916 kg of Silicon Carbide Crude; this norm is suspended and applicants must ensure imported inputs correspond to the goods declared and used in the export product, conforming to the prescribed input-output determination.
