Chlorine treated as a by-product where it lacked equal economic importance to caustic soda for costing and anti-dumping purposes.

Chlorine arising in caustic soda manufacture was held not to be of equal economic importance with caustic soda for costing and anti-dumping purposes. The costing framework under para 12 of Schedule III of the Cost Accounting Records (Caustic Soda) Rules, 1967 applies joint-cost apportionment only where multiple products of comparable economic value emerge from the same process. On the evidence, chlorine's storage and transport constraints, limited downstream integration, and consistent treatment as a by-product in the Indian context supported by cost audit material showed that it did not qualify as a joint product. The result was that chlorine remained a by-product and the challenge to the designated authority's finding and the related anti-dumping notifications failed.

Issues: Whether chlorine arising in the manufacture of caustic soda was of equal economic importance so as to be treated as a joint product, or whether it was correctly treated as a by-product for determining the non-injurious price and anti-dumping duty.

Analysis: The applicable costing framework under para 12 of Schedule III of the Cost Accounting Records (Caustic Soda) Rules, 1967 contemplates apportionment of joint costs only where more than one product of equal economic importance arises from the same process. The expression was applied in its commercial sense, requiring substantial and comparable economic return from the products. On the evidence, chlorine was found to face practical constraints of storage and transport, and the domestic industry had not achieved substantial downstream integration or captive consumption sufficient to place chlorine on the same footing as caustic soda. The cost audit material also showed that chlorine had been consistently treated as a by-product in the Indian context. The fact that chlorine may command significant value at times did not establish equal economic importance for the domestic industry.

Conclusion: Chlorine was not of equal economic importance and was rightly treated as a by-product. The challenge to the designated authority's finding and the consequent anti-dumping notifications failed.
