Of cast iron

This subheading includes fittings of malleable cast iron, which is an intermediate product between lamellar graphite iron (grey iron) and cast steel. Malleable cast iron can be easily cast and becomes tough and malleable after suitable heat treatment. During the heat treatment, the carbon partly disappears or changes its make-up; it finally deposits in the form of nodules which do not impair metallic cohesion to such an extent as the graphite flakes in grey cast iron.

Where the carbon content is 2 % or less by weight, the products are regarded as being of cast steel and fall in subheading 7307 19 90 (see note 1 to this chapter).

See also the explanatory note to subheadings 7307 11 10 and 7307 11 90 , second paragraph.

This subheading also includes fittings of spheroidal graphite cast iron.’;
