27.11 - Petroleum gases and other gaseous hydrocarbons. - Liquefied : 2711.11 - - Naturalgas - - Propane 2711.13 - - Butanes 27 11.14 - - Ethylene, propylene, butylene and butadiene 2711.19 - - Other 2711.12 - In gaseous state : - - Natura1gas 2711.29 - - Other 2711.21 This heading covers crude gaseous h drocarbons obtained as natural gases or from petroleum, or produced chemically. Methane an propane are, however, included even when pure. 2' These hydrocarbons are gaseous at a temperature of 15 "C and under a pressure of 1,013 millibars (101.3 kPa). They may be presented under pressure as liquids in metal containers and are often treated, as a safety measure, by the addition of small quantities of highly odoriferous substances to indicate leaks. They include, in particular, the following gases, whether or not liquefied : I. Methane and propane, whether or not pure. 11. Ethane and eth lene less than 95 % pure. (Ethane and ethylene not less than 95 % pure fall in heading 29. 1.) i 111. Propene ro ylene) less than 90 % pure. (Propene not less than 90 % pure falls in heading $.Of.) IV. Butane containing less than 95 % of n-butane and less than 95 % of isobutane. (Butane containing not less than 95 % of n-butane or isobutane falls in heading 29.01.) V. Butenes utylenes) and butadienes less than 90 % pure. (Butenes and butadienes not less than 90 ?!?Pure fall in heading 29.01.) VI. Intermixtures of propane and butane. The above percentages are calculated by reference to volume for gaseous products and to weight for liquefied products. The heading does not cover : (a) Separate chemically defined hydrocarbons (other than methane and propane in a pure or commercially pure state (heading 29.01). (As re ards such h drocarbons with a ded odoriferous substances, see the General Explanatory Note to hapter 29, Jart A), fifth paragraph. For ethane, ethylene, propene, butane, butenes and butadienes, there are speci c purity criteria as indicated in paragraphs 11,111, IV and V above.) d d (b) Liquefied butane in containers of a kind used for filling or.refillingcigarette or similarlighters and of a capacity not exceeding 300 cm (other than those conshtuhng parts of cigarette or similq lighters) (heading 36.06). (c) Cigarette or other lighter parts containing liquefied butane (heading 96.13).
Notes. 1.- This Chapter does not cover : (a) Separate chemically defined organic compounds, other than pure methane and propane which are to be classified in heading 27.11; (b) Medicaments of heading 30.03 or 30.04; or (c) Mixed unsaturated hydrocarbons of heading 33.01, 33.02 or 38.05. 2.- References in heading 27.10 to “petroleum oils and oils obtained from bituminous minerals” include not only petroleum oils and oils obtained from bituminous minerals but also similar oils, as well as those consisting mainly of mixed unsaturated hydrocarbons, obtained by any process, provided that the weight of the non-aromatic constituents exceeds that of the aromatic constituents. However, the references do not include liquid synthetic polyolefins of which less than 60 % by volume distils at 300 C, after conversion to 1,013 millibars when a reduced-pressure distillation method is used (Chapter 39). 3.- For the purposes of heading 27.10, “waste oils” means waste containing mainly petroleum oils and oils obtained from bituminous minerals (as described in Note 2 to this Chapter), whether or not mixed with water. These include : (a) Such oils no longer fit for use as primary products (for example, used lubricating oils, used hydraulic oils and used transformer oils); (b) Sludge oils from the storage tanks of petroleum oils, mainly containing such oils and a high concentration of additives (for example, chemicals) used in the manufacture of the primary products; and (c) Such oils in the form of emulsions in water or mixtures with water, such as those resulting from oil spills, storage tank washings, or from the use of cutting oils for machining operations. Subheading Notes. 1.- For the purposes of subheading 2701.11, “anthracite” means coal having a volatile matter limit (on a dry, mineral-matter-free basis) not exceeding 14 %. 2.- For the purposes of subheading 2701.12, “bituminous coal” means coal having a volatile matter limit (on a dry, mineral-matter-free basis) exceeding 14 % and a calorific value limit (on a moist, mineral-matter- free basis) equal to or greater than 5,833 kcal/kg. 3.- For the purposes of subheadings 2707.10, 2707.20, 2707.30 and 2707.40 the terms “benzol (benzene)”, “toluol (toluene)”, “xylol (xylenes)” and “naphthalene” apply to products which contain more than 50 % by weight of benzene, toluene, xylenes or naphthalene, respectively. 4.- For the purposes of subheading 2710.12, “light oils and preparations” are those of which 90 % or more by volume (including losses) distil at 210 °C according to the ISO 3405 method (equivalent to the ASTM D 86 method). 5.- For the purposes of the subheadings of heading 27.10, the term “biodiesel” means mono-alkyl esters of fatty acids of a kind used as a fuel, derived from animal, vegetable or microbial fats and oils whether or not used.
