# The Customs (Origin of Chargeable Goods: Developing Countries Trading Scheme) Regulations 2023, Paragraph 6.2


For the purposes of headings 2710, 2711 and 2712, the “specific processes” are the following:
vacuum-distillation;
redistillation by a very thorough fractionation-process;
cracking;
reforming;
extraction by means of selective solvents;
the process comprising all of the following operations: processing with concentrated sulphuric acid, oleum or sulphuric anhydride; neutralisation with alkaline agents; decolourisation and purification with naturally-active earth, activated earth, activated charcoal or bauxite;
polymerisation;
alkylation;
isomerisation;
in respect of heavy oils of heading 2710 only, desulphurisation with hydrogen, resulting in a reduction of at least 85% of the sulphur-content of the goods processed (ASTM D 1266-59 T method);
in respect of goods of heading 2710 only, deparaffining by a process other than filtering;
in respect of heavy oils of heading 2710 only, treatment with hydrogen, at a pressure of more than 20 bar and a temperature of more than 250 °C, with the use of a catalyst, other than to effect desulphurisation, when the hydrogen constitutes an active element in a chemical reaction. However, the further treatment, with hydrogen, of lubricating oils of heading 2710 (e.g. hydrofinishing or decolourisation), in order, more especially, to improve colour or stability is not to be deemed to be a specific process;
in respect of fuel oils of heading 2710 only, atmospheric distillation, on condition that less than 30% of these goods distils, by volume, including losses, at 300 °C, by the ASTM D 86 method;
in respect of heavy oils other than gas oils and fuel oils of heading 2710 only, treatment by means of a high-frequency electrical brush-discharge;
in respect of crude goods (other than petroleum jelly, ozokerite, lignite wax or peat wax, paraffin wax containing by weight less than 0.75% of oil) of heading 2712 only, de-oiling by fractional crystallisation.
