Input-output norms for chemical exports require imported inputs to match actual usage in the export manufacturing process.

Standard input-output norms for Tribasic Lead Sulphate (100% purity) under SION A1203 specify conversion proportions, exemplified by lead ingots at 0.89 kg per 1 kg input, and require determination of proportions of inputs usable or required in manufacture. Applicants must ensure imported goods are those actually used or required in the export product, maintaining consistency between sought imports and actual usage.
