CLASSIFICAÇÃO DE MERCADORIAS

AS NOTAS EXPLICATIVAS DE UMA NOVA POSIÇÃO: 3826 Na posição 3826 só se classificam o biodiesel e suas misturas, que não contenham ou que contenham menos de 70%, em peso, de óleos de petróleo ou de óleos minerais betuminosos. As NESH dessa posição ainda não foram traduzidas para o português, mas em inglês elas elas têm o seguinte teor: Biodiesel consists of mono-alkyl esters of fatty acids of various chain lengths, immiscible with water, with a high boiling point, low vapour pressure and a viscosity similar to that of diesel oil produced from petroleum.  Biodiesel is typically made by a chemical process called transesterification, whereby the fatty acids in oils or fats react with an alcohol (usually methanol or ethanol) in the presence of a catalyst to form the desired esters. It can be obtained from vegetable oils (e.g., rapeseed, soya-bean, palm, sunflower, cotton-seed, jatropha), from animal fats (e.g., lard, tallow) or from used oils or fats (e.g., frying oils, recycled cooking grease). Biodiesel itself contains neither petroleum oils nor oils obtained from bituminous minerals but can be mixed or blended with distillate fuels obtained from petroleum or bituminous minerals (e.g., diesel, kerosene, heating oil).  Biodiesel can be used as fuel for compression-ignition internal combustion piston engines, production of thermal energy or similar uses. This heading excludes : (a)   Mixtures containing, by weight, 70 % or more of petroleum oils or of oils obtained from bituminous minerals (heading 27.10). (b)   Products derived from vegetable oils which have been fully deoxygenated and consist only of aliphatic hydrocarbon chains (heading 27.10). Cesar Olivier Dalston, http://www.daclam.com.br/.
