1. in respect of heavy oils of heading ex2710 only, treatment with hydrogen, at a pressure of more than 20 bar and a temperature of more than 250 oC, with the use of a catalyst, other than to effect desulphurisation, when the hydrogen constitutes an active element in a chemical reaction. The further treatment, with hydrogen, of lubricating oils of heading ex2710(e.g. hydrofinishing or decolourisation), in order, more especially, to improve colour or stability shall not, however, be deemed to be a specific process;
