Shuttle Race Top Spring: SION suspended; input-output norms set input proportions and require imports to match export use. Suspension of the Standard Input-Output Norms for Shuttle Race Top Spring is noted; the entry records an input-output ratio (1 kg output linked with 2.00 kg MS/alloy steel bars/rods) and requires determination of input proportions and an assurance that imported goods are those used or required in the export product.
