Standard input-output norms restrict permitted raw inputs for grey clinker exports and require import-use verification.

Standard input-output norms set permissible inputs and quantitative input-output ratios for production of grey clinker, listing alternatives such as coal or raw petroleum coke, bauxite meeting an alumina threshold, magnesite refractory or chrome bricks, and furnace oil or naphtha; the SION for Grey Clinker is suspended. Applicants must ensure imported goods are those used or required in the declared export product, and authorities will determine the proportions of inputs usable in manufacture of resultant products.
