For the classification of ferro-alloys in the subheadings of 7202 the following should be observed: A ferro-alloy is considered as binary and classified under the relevant subheading (if it exists) if only one of the alloy elements exceeds the minimum percentage laid down in Chapter Note 1(c); by analogy, it is considered respectively as ternary or quarternary if two or three alloy elements exceed the minimum percentage. For the application of this Note the unspecified "other elements" referred to in Chapter Note 1(c) must each exceed 10% by weight. Additional Note 1. Throughout this Schedule "high alloy steel" means alloy steels containing by weight one or more of the following elements in the proportion shown: a. 2% or more of manganese b. 2% or more of silicon c. 0.5% or more of nickel d. 1% or more of chromium e. 0.1% or more of molybdenum f. 0.1% or more of vanadium g. 0.3% or more of tungsten h. 0.3% or more of cobalt i. 0.8% or more of copper j. 0.1% or more of any other alloy element not being lead, phosphorus, sulphur, aluminium or carbon.
