The article is devoted to developing a rapid control method of transported goods declaration authenticity. Currently there is increasing share of biofuels on international market and in export-import operations. Customs control of fuels gives a particular attention to correct verification of the declared code in accordance with the Commodity Nomenclature of Foreign Economic Activity of the Eurasian Economic Union (hereinafter referred to as the CN of the EAEEU). Biodiesel-containing fuels have peculiarities of classification in accordance with the CN of the EAEEU due to specific chemical composition. The standard method of determination of biodiesel fuels’ composition, according to GOST 33077-2014, using spectroscopy in the mid-infrared region has a limited measurements range for the customs purposes, does not allow preliminary verification of authenticity of goods’ declaration, and requires delivery of samples to the laboratory. A method for rapid determination of a group of petroleum fuels by combining infrared spectrometry and chemometrics methods was developed. Spectral data of petroleum fuels containing and not containing biodiesel were analyzed, and calibration models were constructed using the method of projection on the latent structures (PLS-DA). The model of discriminatory analysis using the regression on latent structures allowed to separate quite clearly fuels belonging to different classes or goods’ types according to the CN of the EAEEU. Attributing a fuel sample spectrum to a separate class indicates that the fuel belongs to a group similar to other samples of this class. The problem of classification in the fuel analysis was solved using the chemometric method. The proposed method will provide rapid verification of authenticity of the fuel declaration during customs inspection of goods.
