Facts of the present case – The present application was filed by MetTube Copper India Private Limited seeking initiation of an anti-subsidy/countervailing duty investigation into imports of the subject goods from China PR, Thailand and Viet Nam. The domestic industry alleged that the subsidized imports of the subject goods from the subject countries are materially retarding the establishment of the domestic industry in India and has furnished prima facie evidence in support thereof. The Authority has noted that the demand for the subject goods in India was met almost entirely through imports until the applicant commenced production, that the subject imports increased over the injury period and continued to account for the predominant share of the demand in India during the period of investigation, and that the domestic industry, in its first full year of production, was able to secure only a marginal share of that demand. The landed price of the subject imports remained below both the cost of sales and the net sales realisation of the domestic industry in each year in which it operated and undercut its prices. The domestic industry was unable to raise its selling price to the level of its cost of sales, its production of the subject goods remained a small proportion of the capacity installed for the grooving operation, its inventories increased, and its profits, cash profits and return on capital employed were negative in both years of its operation. The Authority, having been prima facie satisfied with the information concerning existence of countervailable subsidies on production and export of the subject goods in the subject countries, the consequential material retardation of the establishment of the domestic industry as a result of the alleged subsidized imports and the causal link between such injury and the subsidized imports, has initiated the investigation vide Notification No. 6/54/2026-DGTR.
