<h1>SION entry suspended for nickel sulphate; 1 kg equals 0.225 kg nickel metal; import inputs must match exported products</h1> Standard input-output norms for nickel sulphate under chemical and allied products indicate that the SION entry is suspended by a public notice; the specified ratio lists 1 kg of nickel sulphate corresponding to 0.225 kg of nickel metal in briquette form. The schedule requires determination of input proportions usable or required to manufacture resultant products and obliges applicants to ensure imported goods match the inputs actually used or required in the declared export product.
